This editorial produces an outline regarding several crucial measures which you'll find primarily outlined in microphone specification reports: frequency response, sensitivity, impedance, self noise level, and signal to noise ratio. Awareness of those specifications does help every time struggling to choose the best microphones to order regarding a distinct use.
Frequency response measures how a microphone responds to distinctive audio frequencies. An ideal "flat" response (equal sensitivity) microphone would likely respond equally to all frequencies inside the hearable range. This results in a a whole lot more complete reproduction of sound plus supplies the purest audio.
The fact is that even microphones which have been advertised as having a "flat response" may well deviate a bit at various wavelengths. Sometimes, specification sheets likely will report frequency response as a setting like "20Hz to 20kHz", meaning that the microphone could possibly replicate sounds that end up within that scope. Exactly what this fails to indicate is just how appropriately the numerous individual wavelengths are going to be reproduced.
A bunch of mics can be purposely produced to behave in different ways to certain wavelengths. As an example, musical instrument mics intended for bass percussion will be engineered to be much more sensitive to reduced wavelengths when singing mics would definitely be far more sensitive to the frequency of a singer's tone of voice.
As a typical rule of thumb, condenser mics come with flatter frequency responses compared to dynamic. This will mean that a condenser would regularly be the more suitable solution when accuracy of audio reproduction will be the primary aim.
Self noise is the electrical hiss that a microphone lets out. Generally the self noise specification is "A weighted", which means that the lowest and highest wavelengths actually are flattened within the response curve, to better imitate the signal response of the human ear. As a general rule, an A Weighted self noise specification of 18dB SPL and less is incredible (totally quiet), 28dB SPL is useful, and anything over 35db SPL isn't good for quality sound recordings.
