**Specifically, we have taken into account recommendations provided on-line by knowbrainer and emicrophones In significantly quieter environments the differences between microphones can be expected to be somewhat less. *Our true "proving ground" for the quality of a microphone is our experience on a busy and noisy hospital ward. We will provide relative rating of microphones using a scale of 1-5, shown visually as follows: Fair ratings provided by other microphone dealers**.comments and evaluations posted on on-line forums.our own experience in using these microphones*.
What we have used to develop our rating for each microphone is admittedly somewhat subjective and is based on a series of factors, including: Further complicating matters is the likely variability of microphones based on dictation environment, user voice qualities, dictation style, and computer. Microphone Selection Guide: Our Rating SystemĬomparing microphones is a difficult task as objective criteria for such comparisons are difficult if not impossible to develop.
You can read more about these devices near the bottom of this guide. If you purchase a standard analog microphone without an integrated USB sound adapter, we recommend purchasing an external USB sound adapter and interfacing your microphone to your computer with this adapter.
Several microphones include built in USB devices, including the VXI Talk Pro USB 100 & 200, the Andrea NC 181 an 185 VM USB mics, the Speechware 6-in-1 microphone, the Samson Q1U, the Dictaphone PowerMic II, the Philips SpeechMic, and several of the wireless microphones such as the Sennheiser DW Office and Jabra 9470. The bottom line is that use of an external sound conversion device (adapter) is not essential but is highly recommended.
Generally such microphones include a very small "pre-amplifier" to boost this signal and which requires application of a small external voltage. Virtually all of the commonly used microphones employed with personal computers are termed electret microphones and operate by using a permanently electrically charged material which alters its voltage when deflected by sound waves.
