How to Position a Microphone


The golden rule of microphone placement is get the distance right. In general, place the microphone as close as practical to the sound source without getting so close that you introduce unwanted effects (see below).

The aim is to achieve a good balance between the subject sound and the ambient noise. In most cases you want the subject sound to be the clear focus, filled out with a moderate or low level of ambient noise. The desired balance will vary depending on the situation and the required effect. For example, interviews usually work best with very low ambient noise. However if you want to point out to your audience that the surroundings are very noisy you could hold the mic slightly further away from the subject.

It is possible to get too close. Some examples:

Phase Problems

When using more than one microphone you need to be wary of phasing, or cancellation. Due to the way sound waves interfere with each other, problems can occur when the same sound source is picked up from different mics placed at slightly different distances. A common example is an interview situation in which two people each have a hand-held mic - when one person talks they are picked up by both mics and the resulting interference creates a phasing effect.

Think Laterally

You don't always have to conform to standard ways of doing things. As long as you're not placing a microphone in danger there's no reason not to use them in unusual positions. For example, lavalier mics can be very versatile due to their small size - they can be placed in positions which would be unrealistic for larger mics.


Snare Drum Microphone
Guitar amps are miced very closely. This helps keep the sound isolated from the rest of the stage noise. Theoretically the amp will not create any level burst strong enough to distort the microphone.

Snare drum mics need to be close to the skin without getting in the way of the drummer or risking damage.
