This is an accuracy instrument used to measure the level of sound. Its ability to give more accurate results depends on its sound sensitive microphone that picks up the pressure in the sound and translates it into decibel (dB) readings, and calibration ensures that such metres will give reliable standardised measurements, ideally acceptable for professional usage in acoustics, construction, and environmental monitoring, among others. The calibration of decibel meters can be considered as either compact and lightweight or especially calibrated. They are typically provided with adjustable frequency weighting, for example, A, C or Z to evaluate different sound profiles, and are fitted with logging data or real-time analysis.
Calibrated decibel meter are indispensable tools that guarantee compliance with noise regulations and workplace safety for maintenance in a number of environments.
