Portable sound meters, also known as sound level meters or decibel meters, are handheld electronic devices designed to measure sound pressure levels in various environments.
1 These devices utilize a microphone to capture sound waves, which are then converted into electrical signals and processed to display a decibel (dB) reading. 2 They are used for a wide range of applications, including occupational safety, environmental noise monitoring, and acoustic analysis, allowing users to assess and control noise levels to ensure compliance with regulations and protect hearing health. Modern portable sound meters often feature digital displays, data logging capabilities, and connectivity options for easy data transfer and analysis.
