Decibel Measurement Instrument

A decibel meter receives sound waves through its built-in microphone, converts sound pressure into an electrical signal, and then displays the decibel value after logarithmic calculation. It is used in areas such as environmental noise monitoring, industrial equipment sound level inspection, and hearing protection assessment.
Selection
When selecting, focus on the measurement range covering the application scenarios, accuracy meeting detection standards, and the availability of frequency weighting and time weighting functions. Consider the validity of calibration certificates, environmental adaptability, data storage requirements, and ensure the interface type is compatible with subsequent analysis tools.
