Which Microphone Should I Use?
Free Field - Designed to be used when the field of measurement is open and not filled with hard, reflective surfaces (in other words, when the measurement is being taken in an open area). There are two ways of using a free field microphone:
Pointed directly at the sound source of interest, for example when getting a sound profile for a piece of equipment or making sound power measurements
Placed in the center of all sound sources and pointed 90 degrees away (up) – for example in many environmental studies, National Park studies, traffic studies, or construction noise studies when the surrounding environment is wide open.
Random Incidence - Designed to measure a sound field with multiple sources in multiple directions. Used in reflective areas, random incidence microphones react equally to pressure waves from every direction. Typical applications include
Indoor crowd noise
Building acoustics (classroom, theater, sanctuary)
Sound chambers
Pressure Field - Designed to measure the sound pressure in front of the diaphragm. Pressure microphones typically allow for a greater dynamic range, and have a very flat response across the full frequency spectrum. The pressure microphones offered by TMS for rent feature low sensitivity that allows the noise monitoring system to measure higher dB levels without overloading.
*Microphone range varies with meter used, preamplifier, etc. Contact our rental team for more details.
