This article has a review on the subject of five imperative standards which are typically identified in microphone spec pages: frequency response, sensitivity, impedance, self noise level, as well as signal to noise ratio. Getting a grip on those specs will help the moment attempting to choose the very best condenser microphones to obtain needed for a specialized application.
Frequency response calculates how a microphone behaves to a range of sound wavelengths. An ideal "flat" response (equal sensitivity) microphone would probably react equally to all frequencies within the audible spectrum. This results in a much more genuine reproduction of sound plus delivers the purest audio.
The honest truth is that even microphones which are promoted as possessing a "flat response" can easily deviate to some degree at various frequencies. Generally speaking, spec pages would certainly list frequency response as a range like "20Hz to 20kHz", meaning that the microphone might reproduce sounds that end up inside that span. What this isn't going to identify is how completely the many individual wavelengths would be reproduced.
A couple of microphones can be specially created to respond distinctly to specific frequencies. As one example, musical instrument microphones meant for bass drums are actually engineered to be a whole lot more receptive to reduced frequencies though vocal microphones would be considerably more receptive to the pitch of a performer's voice.
As a traditional rule of thumb, condenser mics come with flatter frequency responses in comparison with dynamic. This signifies that a condenser would typically be the more likely option when preciseness of audio reproduction is considered the main goal.
Self noise is the electrical hiss which a microphone releases. Primarily the self noise spec is "A weighted", which means that the lowest and maximum frequencies are flattened inside the response curve, to better duplicate the signal response of the human ear. As a typical rule, an A Weighted self noise spec of 18dB SPL and less is superb (absolutely quiet), 28dB SPL is good, and anything beyond 35db SPL will not be appropriate for quality sound recordings.
