This posting includes a review on 5 critical measures that are routinely displayed in microphone spec documents: frequency response, sensitivity, impedance, self noise level, along with signal to noise ratio. Learning these specs will help if attempting to go for the very best microphones to get hold of with regard to a unique use.
Frequency response measures how a microphone takes action to distinctive noise wavelengths. A superb "flat" response (equivalent sensitivity) microphone would undoubtedly behave the same to all frequencies in the perceptible range. This will cause a way more authentic reproduction of sound plus produces the purest audio.
The real truth is that even microphones which are usually announced as having a "flat response" can possibly deviate just a bit at particular wavelengths. Usually, specification documents are likely to report frequency response as a range like "20Hz to 20kHz", which means that the microphone definitely will recreate sounds that end up within that limit. What precisely this does not identify is how completely the many individual frequencies shall be reproduced.
Numerous microphones are deliberately designed to react in different ways to specific wavelengths. One example is, musical instrument mics designed for bass percussion happen to be made for being a good deal more responsive to reduced frequencies though voice mics will probably be a great deal more sensitive to the frequency of a girl's pitch.
As a traditional rule of thumb, condenser microphones contain flatter frequency responses than dynamic. This means that a condenser would typically be the more appropriate choice in the event that detail of sound reproduction is the definitive goal.
Self noise is the electrical hiss which a microphone lets out. Almost always the self noise spec is "A weighted", meaning that the minimum and highest frequencies will be flattened within the response curve, to better recreate the signal response of the human ear. For a general rule, an A Weighted self noise spec of 18dB SPL or less is wonderful (extremely quiet), 28dB SPL is useful, while everything beyond 35db SPL is not good for quality music recordings.
