The advent of communication technology created great attention for a computer peripheral that was once not thought to be a necessary part of computers – the microphone. With the emergence of Voice over Internet Protocol telephones, microphones gained great importance in the IP communication field. Several microphones became available to the general market in the recent years for the main purpose of using them in web communication. There are many kinds of microphones that can be used with VoIP phones, here are the popular ones: Boom or Desktop Microphones – Also known as omni directional microphones (which pick up sounds from every direction), these ones are situated on a positional boom and are usually installed on top of the desk or the monitor. The good thing about them is that they can be used hands free because of their great sensitivity. This kind of microphone allow several people to speak at the same time, which can be very handy for conferences among groups of people in different places. One possible disadvantage is that it may pick up background noises and other unwanted voices, or get feedbacks with the PC speakers. Built-in Microphones – They are typically omni directional microphones that came together with the computer and are incorporated into the monitor. This is a popular feature with laptop computers. Compact and conveniently positioned, these microphones can be used hands-free too, and can pick up several people’s voices, useful for conferences. Like other omni directional microphones, built-in microphones can pick up unwanted background voices. Moreover, such microphones are inflexible and cannot be positioned without moving the entire system. Handset Microphones – these are quite common for VoIP applications. These are unidirectional and seem like a regular telephone handset with an earpiece and a mouthpiece. Such microphones give a familiar feel of traditional phones. Audio quality is usually good for speech, allowing the most consistent feel with Voice over IP calls. However, like the telephone handset, this can be quite inconvenient for long conversations. Being unidirectional, only one person can speak at a time, though it is easy to pass it to another person should the need arise. Wireless Microphones– these are cable-free microphones, operating usually through Bluetooh ports. Such microphones can be incorporated with headsets and can either be unidirectional or omni directional. These are definitely hands free since there are no wires used and they can be attached to the head or the ear of the speaker. The sound quality is excellent for speech especially when coupled with noise canceling features. However, compatibility is not always guaranteed as not all computers are equipped with Bluetooth or infra-red ports. Handheld Microphones – these are comparable to those used by public speakers and pop singers. These may be either unidirectional or omni directional. One may have the option to use a microphone stand to make this one hands free. But without the stand, it could be quite inconvenient to use. Lapel microphones – normally omni directional, these microphones can be attached onto the clothes or clipped somewhere else. These microphones work just like desktop microphones with the added option of being near the speaker. Communication has greatly changed with the emergence of VoIP. Now people have many choices and they can use different types of microphones to reach people the way they want to.
