mittausmikrofon

A mittausmikrofon, often translated as a measurement microphone, is a specialized microphone designed for accurate and calibrated sound level measurements. Unlike standard microphones used for music recording or public address systems, measurement microphones are engineered to have a very flat and consistent frequency response across the audible spectrum. This flat response is crucial for ensuring that the microphone accurately captures the sound pressure levels without introducing its own coloration or distortion.

The primary purpose of a measurement microphone is to serve as a precise transducer in acoustic measurement equipment. They are used in a variety of applications, including environmental noise monitoring, architectural acoustics, audio system calibration, and research and development in acoustics and audio engineering. The calibration of a measurement microphone is essential, and its sensitivity is typically specified in millivolts per Pascal (mV/Pa) or decibels relative to 1 Volt per Pascal (dB re 1V/Pa). This calibration allows for the conversion of the microphone's electrical output signal into precise sound pressure level readings in decibels.

Measurement microphones are often designed with a small diaphragm to minimize sound diffraction effects, which can alter the sound field being measured. They are also built to withstand various environmental conditions and are typically omnidirectional, meaning they pick up sound equally from all directions, which is often desirable for general sound level measurements. The accuracy and reliability of acoustic measurements heavily depend on the quality and proper use of the measurement microphone.
