Dynamic Microphones – Recording Your Voice

This study gives you an overview on the subject of a few beneficial measures that are ordinarily listed in microphone spec reports: frequency response, sensitivity, impedance, self noise level, and also signal to noise ratio. Mastering these technical specs will help the moment trying to select the perfect dynamic microphones to buy regarding a detailed use.

Frequency response calculates how a microphone responds to varied sound frequencies. An excellent “flat” response (identical sensitivity) microphone normally would behave equally to all frequencies inside the audible spectrum. This produces a much more genuine reproduction of sound and also provides the best audio.

The inescapable fact is that even microphones that are presented as having a “flat response” can possibly deviate somewhat at specific frequencies. Customarily, specification pages may report frequency response as a range like “20Hz to 20kHz”, which means that the microphone should be able to replicate sounds that slide among that spectrum. Everything that this doesn’t explain is just how adequately the many individual frequencies will probably be reproduced.

Lots of mics happen to be deliberately built to react in a different way to particular frequencies. One example is, instrument microphones intended for bass drums are actually built for being much more receptive to reduced wavelengths while vocal microphones will probably be far more responsive to the pitch of a girl’s tone of voice.

As a common rule of thumb, condenser microphones possess flatter frequency responses in comparison with dynamic. This implies that a condenser will tend to be the greater choice if accuracy of sound reproduction is definitely the main aim.

Self noise is the electrical hiss that a microphone releases. In most cases the self noise specification is “A weighted”, meaning that the minimum and highest wavelengths are flattened within the response curve, to better duplicate the signal response of the human ear. As a typical guideline, an A Weighted self noise spec of 18dB SPL or less is fabulous (tremendously quiet), 28dB SPL is okay, and anything beyond 35db SPL is not well suited for quality music recordings.
