This information includes a summary regarding several important options which may be frequently outlined in microphone spec pages: frequency response, sensitivity, impedance, self noise level, as well as signal to noise ratio. Getting a grip on those specs could help each time attempting to select the ideal condenser microphones to order designed for a selected application.
Frequency response calculates how a microphone reacts to various sound frequencies. A superb "flat" response (identical sensitivity) microphone would undoubtedly behave equally to all frequencies in the audible spectrum. This results in a a great deal more authentic reproduction of sound plus provides the best audio.
The honest truth is that even microphones that are marketed as owning a "flat response" may possibly deviate to some degree at specific frequencies. Typically, specification documents may specify frequency response as a range like "20Hz to 20kHz", meaning that the microphone would duplicate sounds which slide within that array. Something that this does not reveal is how specifically the different individual wavelengths are going to be reproduced.
A handful of mics are specially developed to behave in a different way to specific frequencies. Here is an example, musical instrument mics meant for bass percussion may be designed to be significantly more responsive to reduced frequencies while vocal mics will be a great deal more sensitive to the frequency of a guy's pitch.
As a typical rule of thumb, condenser microphones contain flatter frequency responses versus dynamic. This suggests that a condenser will tend to be the more likely solution whenever detail of sound reproduction is most likely the absolute goal.
Self noise is the electrical hiss which a microphone emits. Normally the self noise spec is "A weighted", which means that the lowest and maximum wavelengths are really flattened inside the response curve, to better mimic the signal response of the human ear. For a common principle, an A Weighted self noise specification of 18dB SPL or lower is fantastic (absolutely quiet), 28dB SPL is okay, and everything over 35db SPL isn't good for quality audio recordings.
