This page features an overview on the subject of a few important measures that will be in general outlined in microphone specification documents: frequency response, sensitivity, impedance, self noise level, and signal to noise ratio. Being aware of those specifications might help the moment struggling to figure out the finest dynamic microphones to order suitable for a specific application.
Frequency response calculates how a microphone takes action to distinctive noise wavelengths. An optimal "flat" response (equivalent sensitivity) microphone would certainly respond equally to all frequencies within the hearable spectrum. This triggers a way more detailed reproduction of sound and yields the purest sound.
The idea is that even microphones which might be announced as owning a "flat response" could deviate a little at specific frequencies. In general, specification reports will definitely list frequency response as a setting like "20Hz to 20kHz", meaning that the microphone most likely will duplicate sounds which drop among that scale. Everything that this will not express is how specifically the many individual wavelengths will be reproduced.
A quantity of mics happen to be intentionally created to respond in a different way to specific wavelengths. One example is, instrument microphones for bass percussion are normally constructed to be significantly more reactive to reduced wavelengths though vocal microphones would definitely be considerably more reactive to the pitch of a human tone of voice.
As a traditional rule of thumb, condenser microphones have got flatter frequency responses as compared to dynamic. This signifies that a condenser will tend to be the greater option in the instance that preciseness of audio reproduction is going to be main goal.
Self noise is the electrical hiss which the microphone yields. Routinely the self noise spec is "A weighted", meaning that the lowest and maximum wavelengths will be flattened in the response curve, to better imitate the signal response of the human ear. As a common rule, an A Weighted self noise spec of 18dB SPL or lower is fantastic (totally quiet), 28dB SPL is useful, and something over 35db SPL is not great for quality audio recordings.
