Measurement microphones are also omnidirectional and hence are better suited to capturing reflections at all angles equally well. Measurement microphones often have much lower sensitivity (allowing for higher inputs exceeding 100dBSPL) and lower self-noise characteristics. Note that while there are some recording microphones that may appear to have suitably flat response curves for measurement, that only tells part of the story. This often means a small-diaphragm condenser (or electret) microphone, and you can obtain these microphones for as little as $70. In general we suggest that you use a microphone that is specified for test and/or measurement use. F to 176 deg.Acoustic measurements require the use of a suitable microphone, but not necessarily an expensive one.
