A Noise Decibel Meter or Noise Level Sensor is a device used to measure the sound pressure level of an acoustic wave. It measures the intensity of sound and the sound pressure level in decibels (dB) and is commonly used to measure environmental noise levels, occupational noise levels, and general acoustic analysis.
These meters are typically portable and have a microphone that is placed in the vicinity of the sound source to measure the sound levels. They can measure the sound pressure level in real time, and some models also have the capability to store the data for later analysis.
Noise decibel meters are used in a variety of applications, including environmental noise monitoring, noise mapping, building acoustics, and occupational noise exposure assessment. They are also commonly used in the music and entertainment industry to monitor sound levels during concerts and events.
Some noise decibel meters are designed to be integrated with other systems, such as building automation systems or industrial process control systems, to provide real-time monitoring and control of noise levels.
Noise decibel meters are available in a variety of models and specifications, with features such as frequency weighting, time weighting, and data logging capabilities. The choice of meter depends on the application and the specific requirements of the user.
