A measurement microphone is a specialized type of microphone that is designed to capture sound with precision and accuracy. It is an essential tool in the field of acoustics, as it allows for the measurement and analysis of sound waves and their behavior in different environments. Measurement microphones are used in a wide range of applications, from testing and calibration of audio equipment to acoustic measurements in spaces such as concert halls, recording studios, and industrial settings. They are designed to have a flat frequency response, meaning that they accurately reproduce the sound without introducing any coloration or distortion.
With the use of measurement microphones, acousticians can evaluate the performance of loudspeakers, room acoustics, and other sound systems. The data collected from these measurements can be used to optimize the acoustic environment for a particular application or to identify and correct acoustic problems.
GRAS is a worldwide leader in the sound and vibration industry. They develop and manufacture state-of-the-art measurement microphones and related equipment for industries where acoustic measuring accuracy and repeatability are of utmost importance.
GRAS measurement microphones can divide into Free-field measurement microphone, Pressure measurement microphone, and Random-incidence measurement microphone covering various frequency ranges, dynamic ranges and application situations. The differences between measurement microphones from group to group are at the higher frequencies, where the measurement microphone size becomes comparable with the wavelengths of the sound being measured. Pick your choice of measurement microphone set or get guidance from the measurement microphone guide.
With this guide, you can find help to select the right measurement microphone for your applications. Get introduced to selecting externally polarized or prepolarized measurement microphones, free-field measurement microphone, pressure or random incidence measurement microphones as well as learning about the dynamic range of a measurement microphone and the frequency range of a measurement microphone.
