Again another article i thought was interesting around the business of headset’s, what would you do if i didn’t post this ehh? you would have to find the initial content, the chances you found it could be slim, so think yourself lucky that i’ve shared this wonderful article with you.

Audio surveillance is the act of listening to third-party conversations and recording them. This technique is frequently used by law enforcement, private detectives and government spy agencies. Most audio surveillance consists of either bugging a room, wearing a wire, tapping a phone or distance listening. Each provides distinct advantages and disadvantages, depending on the situation.

Wiretapping is one of the most common and simple form of audio surveillance. This is preferred because it is highly inconspicuous and allows for two sides of a conversation to be clearly recorded. Small audio devices, commonly called bugs, are attached to the internal circuitry of a telephone to pick up a conversation. A signal is wirelessly transmitted to another device that records the conversation. The drawback of this method is getting access to a subject’s telephone to properly wiretap it.

audio surveillanceA room microphone is another audio surveillance technique that often is utilized. This involves planting a wireless microphone in a room to pick up conversations. Disguised room microphones are available to look like pens, clocks, stuffed animals and a variety of other covert forms. This microphone sends a signal to a receiver, just like a wiretap does, and the signal can be directly recorded. The disadvantage here is access to some rooms and getting only one side of a phone conversation if it takes place in that room.

Concealable transmitters known as body wires are well-known devices that have been featured in many television shows and movies. A small microphone and transmitting device are worn under the clothes of a person in order to send a signal back to a receiver and record a conversation. This allows the person wearing the wire to ask questions and get specific details that simply listening to other people’s conversations could not provide. The disadvantage of this method is getting access to the person needed to be recorded and also concealing the microphone in a way that hides it but allows for clear recording.

Long-distance microphones are another covert means of audio surveillance. A parabolic microphone, often called a shotgun microphone because of its long shape, has a powerful ability to pick up conversations up to 300 feet (91.4 m) away. Its main disadvantage is its high sensitivity. It can pick up other noises and cannot function if obstructions, such as trees and automobiles, are between the microphone and the conversation.

03. August 2014 · Comments Off on Effective Communication, What is it? · Categories: Telecommunications · Tags:

Effective communication is a somewhat esoteric concept that is frequently applied to business management. It can, however, easily apply to our personal lives as well.

Put simply, effective communication aims at improving our understanding of the emotional content (*taps head and does a bad Bruce Lee impersonation) behind any given information. Theoretically, this understanding makes us more empathic and thus better able to relate to our spouses, co-workers, employers and friends.

effective communicationsEffective communication, then, aims at fostering a deeper understanding between communicators, by creating a stronger emotional resonance.

Experts in the subject maintain that the first step towards becoming a more effective communicator (should you wish to, of course) is to become a better listener. You can do this by fully focusing on the speaker (as opposed to being distracted, or deliberately distracting yourself), not interrupting them and openly demonstrating an interest in what the speaker has to say.

The next step, maintains that the use of open body language (e.g. not crossing your arms) and emphasizing a point via your body (such as tapping your head to indicate thinking ahead) is also very important to effective communication.

Step three is to focus on and thus better manage, your stress. A stressed person, even if their outward demeanour seems pleasant enough, gives off a lot of anxiety, from body language to posture, so it is best to deal with your anxieties privately before dealing with others (where possible).

Of course, effective communication is largely emotion-centric as a concept and so the final point brought up by the article is to improve your own emotional awareness. Essentially, this is the understanding of yourself and what makes you tick. It sounds obvious, even easy, but the truth is that most of us don’t have a clue. If you find yourself entrenched in petty squabbles or constant bickering with your friends, spouse, family or colleagues, then there is a good chance that there is something deeper that is bothering you. With a greater emotional understanding of yourself, not only will you be able to avoid potentially stress-inducing situations, but you should also be able to recognize patterns in others that you have seen in yourself, allowing you to become more empathic and, ultimately, a better communicator.

Essentially, effective communication is all about communicating effectively. It is about improving your understanding of yourself and others around you, in order to live and work with other in a more harmonious way.

Asked by Hiromi in Osaka

Hi Hiromi, How’s life in Japan? I’d love to visit one day, but until then, here’s your answer…

It all depends on how much you sweat. Yes, I know that’s a little bit indelicate of me, but unfortunately it happens to be true. I’ve read many, many customer reviews of otherwise fine and good headsets that claim to be designed for joggers, but that conk out the first time they get significantly wet…

Headsets designed for jogging are often created so that they won’t fall out of your ears as you run, with almost no concern placed on how much you may sweat during the run. Some people sweat a lot and some sweat very little. In either instance, your sweat level needs to be a factor in your purchasing decision (and there’s no nicer way to say it than that!)

Then, another factor to consider is how much the headset will isolate you from your surroundings as you run. Noise cancellation headsets might do a superlative job if you’re running past a noisy construction site, but they aren’t going to be much help in the wake of oncoming traffic. Again, it comes down to individual choice. Some runners subscribe to the Linford Christie ‘bullet from a gun’ mentality, whilst others simply enjoy a bit of exercise, but also like to stay aware of what’s going on around them.

It is also misleading to assume that a branded headset from a sportswear manufacturer is in any way superior to one designed by a trusted electronics firm. In many/most instances, the opposite is actually true.

Sadly, even so called ‘sweat resistant’ headsets are often anything but and there isn’t a lot you can actually do to get your money back. Your best bet, if you ask me, is to buy a mid-range headset, use it specifically for jogging/going to the gym and don’t expect it to last for very long. If it performs badly, chalk it up to experience and buy a different headset, if it lasts for a decent period of time, then replace it with a similar model, or else the same one again.

I’ll be honest; every so often I get one of these questions that I find hard to answer, as no amount of research will really help. Type in the name of any ‘Bluetooth Headset for Jogging’ into Amazon (or whatever the Japanese equivalent of Amazon may be) and you’ll read just as many complaints in the reviews as praises.

Due to this, I’m reluctant to name specific models, because they may not actually work for you. I’d hate to say, “Oh, this headset works really well”, only to have you write back “Does it b*llocks!”. I have personally reviewed several pairs of headphones online (which you can view by clicking HERE), but not any Bluetooth headsets (to the best of my recollection), so I’m afraid that’s all the advice I can give you on this one!

26. June 2014 · Comments Off on How did people communicate with each other 100 years ago? · Categories: Telecommunications · Tags:

Asked by Barbara from Basingstoke

 

Hi Barbara from Basingstoke (I like that, it has a nice ring to it), 

I presume you mean to ask me how people communicated over long distances, because otherwise the answer would simply be ‘they talked to each other, just as they do today’. I’ll give you the benefit of the doubt, but please be more specific in future! (Kidding!)

OK, so 100 years ago, in 1914, the telephone was still in its infancy, relatively speaking. 99 years ago, Thomas Watson made the first coast-to-coast phone call in America, so that should give you some idea of where the telephone was, development wise.

However, the invention had been patented since 1876 and 1877 had seen the first long-distance phone call placed. But by and large, telephones were not an overly common part of people’s lives the way they are now.

More common was the telegraph, which had been knocking around for a while by then. People in official positions tended to use that, but it wouldn’t have been a fixture of regular people’s houses.

Far more common than telephone or telegraph was the postal service. In 1914, if you wanted to contact a friend, relative, or loved one, you wrote to them. The working classes were better educated than at any other time in history (up to that point) and literacy was improving (although it certainly wasn’t at the near-ubiquitous level of today). Letters took a long time to arrive by today’s standards, so they tended to be longer and more absorbing than, say, a Facebook chat is today. In fact, intellectuals, authors and politicians would often engage themselves in long-winded and exhaustive intellectual contests via thorough, essay-length correspondences.

Another option would have been to speak via mutual acquaintances. Literature of the period frequently involves friends using a mutual friend in order to carry on a long-distance discussion and it is my understanding that this was quite a common practice. Interestingly, this may very well have shaped the development of certain customs in society (such as ‘good manners’ vs. ‘bad manners’ regarding correspondence etiquette). With our communication methods of today being so vastly different, it remains to be seen how our society will come to reflect this. 

07. May 2014 · Comments Off on Keeping Up With Current Events – Two Way Radios in Events Management · Categories: Telecommunications · Tags:

From cultural events celebrating the diverse mosaic of British identity, to barnstorming rock n roll gigs, events management is a huge area to be involved in.

The term ‘event’ can be somewhat misleading, because technically everything is an event. Actually, when you look at it like that, maybe it isn’t so misleading after all…

When we use the term event, we could be talking about an indoor conference just as easily as a political rally. Athletic contests, art exhibitions, magic shows; if people attend it, it’s an event, and if it’s an event; it needs a manager.

With such events proving to be a booming industry in modern Britain, there’s never been a better time to be an event manager. However, no matter how good your management skills may be, there is one little device that you simply can’t do without.

Rugged, strong and reliable, the humble two-way radio is a staple of so many activities that it beggars belief. In order for a concert to go as planned, or that installation to be ‘just so’, a manager needs to be in constant contact with the staff who are working under her/him.

A key concern at any event is health and safety and, after that, security. With so many people attending, say, a conference, paramedics need to be on standby in case of any emergency. In addition, fire safety regulations need to be adhered to, as do any building laws that may be in effect.

As for security, in today’s troubled world, the sad truth is that there are a lot of disgruntled people out there, people who will stop at nothing to make their statement. Without dwelling on this terrible fact, we must merely make a solemn mental note that, without radios, it would be far harder for security teams to effectively police such large gatherings of Humanity.

People working backstage at music gigs, from venue staff to roadies, need to be kept abreast of things like weather issues, changes to schedule and ongoing security concerns; only radios have the power to achieve this with any degree of effectiveness.

Events management, then, is a constant challenge, but the smiling faces of the patrons make it all worthwhile.

Everybody from cleaners and vendors, to front office staff and fire marshals, needs to be within easy reach of management; two-way radios not only make this possible, they actually make it easy. More reliable than a phone, more practical than a middleman and far faster than a pager, the two-way radio is absolutely crucial to the success of any big event. 

05. April 2014 · Comments Off on Truly Communication? The Modern Communication : A Normative Critique. · Categories: Telecommunications · Tags:

Communication is the activity of conveying information through the exchange of thoughts, messages, or information, as by speech, visuals, signals, writing, or behavior. It is the meaningful exchange of information between two or more living creatures.
One definition of communication is “any act by which one person gives to or receives from another person information about that person’s needs, desires, perceptions, knowledge, or affective states. Communication may be intentional or unintentional, may involve conventional or unconventional signals, may take linguistic or non-linguistic forms, and may occur through spoken or other modes.”
Communication requires a sender, a message, and a recipient, although the receiver doesn’t have to be present or aware of the sender’s intent to communicate at the time of communication; thus communication can occur across vast distances in time and space. Communication requires that the communicating parties share an area of communicative commonality. The communication process is complete once the receiver understands the sender’s message.
Communicating with others involves three primary steps:
Thought: First, information exists in the mind of the sender. This can be a concept, idea, information, or feelings.
Encoding: Next, a message is sent to a receiver in words or other symbols.
Decoding: Lastly, the receiver translates the words or symbols into a concept or information that a person can understand.
There are a variety of verbal and non-verbal forms of communication. These include body language, eye contact, sign language, haptic communication,and chronemics. Other examples are media content such as pictures, graphics, sound, and writing. The Convention on the Rights of Persons with Disabilities also defines the communication to include the display of text, Braille, tactile communication, large print, accessible multimedia, as well as written and plain language, human-reader, augmentative and alternative modes, means and formats of communication, including accessible information and communication technology. Feedback is a critical component of effective communication.
Verbal communication
Human spoken and pictorial languages can be described as a system of symbols and the grammars by which the symbols are manipulated. The word “language” also refers to common properties of languages. Language learning normally occurs most intensively during human childhood. Most of the thousands of human languages use patterns of sound or gesture for symbols which enable communication with others around them. Languages seem to share certain properties although many of these include exceptions. There is no defined line between a language and a dialect. Constructed languages such as Esperanto, programming languages, and various mathematical formalisms are not necessarily restricted to the properties shared by human languages. Communication is the flow or exchange of information within people or a group of people.
Nonverbal communication
Nonverbal communication describes the process of conveying meaning in the form of non-word messages. Some forms of non verbal communication include chronemics, haptics, gesture, body language or posture, facial expression and eye contact, object communication such as clothing, hairstyles, architecture, symbols, infographics, and tone of voice, as well as through an aggregate of the above. Speech also contains nonverbal elements known as paralanguage. These include voice lesson quality, emotion and speaking style as well as prosodic features such as rhythm, intonation and stress. Research has shown that up to 55% of human communication may occur through non verbal facial expressions, and a further 38% through paralanguage. Likewise, written texts include nonverbal elements such as handwriting style, spatial arrangement of words and the use of emoticons to convey emotional expressions in pictorial form.
Oral communication
Oral communication, while primarily referring to spoken verbal communication, can also employ visual aids and non-verbal elements to support the conveyance of meaning. Oral communication includes speeches, presentations, discussions, and aspects of interpersonal communication. As a type of face-to-face communication, body language and choice tonality play a significant role, and may have a greater impact upon the listener than informational content. This type of communication also garners immediate feedback.
Business communication
A business can flourish only when all objectives of the organization are achieved effectively. For efficiency in an organization, all the people of the organization must be able to convey their message properly.
Written communication and its historical development
Over time the forms of and ideas about communication have evolved through the continuing progression of technology. Advances include communications psychology and media psychology, an emerging field of study.
The progression of written communication can be divided into three “information communication revolutions”:
# Written communication first emerged through the use of pictographs. The pictograms were made in stone, hence written communication was not yet mobile.
# The next step occurred when writing began to appear on paper, papyrus, clay, wax, etc. with common alphabets. Communication became mobile.
# The final stage is characterized by the transfer of information through controlled waves of electromagnetic radiation and other electronic signals.
Communication is thus a process by which meaning is assigned and conveyed in an attempt to create shared understanding. This process, which requires a vast repertoire of skills in interpersonal processing, listening, observing, speaking, questioning, analyzing, gestures, and evaluating enables collaboration and cooperation.
Misunderstandings can be anticipated and solved through formulations, questions and answers, paraphrasing, examples, and stories of strategic talk. Written communication can be clarified by planning follow-up talks on critical written communication as part of the every-day way of doing business. A few minutes spent talking in the present will save valuable time later by avoiding misunderstandings in advance. A frequent method for this purpose is reiterating what one heard in one’s own words and asking the other person if that really was what was meant.
Effective communication
Effective communication occurs when a desired effect is the result of intentional or unintentional information sharing, which is interpreted between multiple entities and acted on in a desired way. This effect also ensures the messages are not distorted during the communication process. Effective communication should generate the desired effect and maintain the effect, with the potential to increase the effect of the message. Therefore, effective communication serves the purpose for which it was planned or designed. Possible purposes might be to elicit change, generate action, create understanding, inform or communicate a certain idea or point of view. When the desired effect is not achieved, factors such as barriers to communication are explored, with the intention being to discover how the communication has been ineffective.
Barriers to effective human communication
Barriers to effective communication can retard or distort the message and intention of the message being conveyed which may result in failure of the communication process or an effect that is undesirable. These include filtering, selective perception, information overload, emotions, language, silence, communication apprehension, gender differences and political correctness
This also includes a lack of expressing “knowledge-appropriate” communication, which occurs when a person uses ambiguous or complex legal words, medical jargon, or descriptions of a situation or environment that is not understood by the recipient. More »

17. December 2013 · Comments Off on Storage Spaces, 2 way Radios used in Warehouse Operations · Categories: Telecommunications · Tags: ,

Most of us don’t really think about it, but warehouses play an important part in our lives. When we shop at a supermarket, visit an electronics store, or order online from a major retailer, we are buying items that, at one time or another, have to be stored somewhere.

Its not just completed products, either. Once an item has been manufactured, it must then be stored before transit, meaning that most factories incorporate a considerable amount of space to the storage of completed products, ready for shipping. More »

16. November 2013 · Comments Off on Why do secret service guys wear those earpieces with the coiled wires instead of something less conspicuous? · Categories: Telecommunications · Tags:

That’s actually a pretty good question. Good quality wireless earpieces are available, affordable and would be far more inconspicuous than the classic ‘wired’ models. So why don’t the secret service make their presence a little more, well, secret?

The main reason is largely psychological in nature (though there will be a technical component later on). You see, if a potential troublemaker looks into a crowd and sees nobody there that he/she identifies with as a threat, then said troublemaker will be far more likely to start making trouble. However, if they notice secret service guys using their trademark earpieces, then they might think twice about it and a lot of unpleasantness can actually be avoided. More »
