Noise Level Sensors for Industrial And Environmental Noise Monitoring
A noise sensor is a device used for detecting and monitoring noise. It realizes the monitoring and control of noise by converting the vibration of sound waves into electrical signals. The core component of the noise sensor is a highly sensitive electret condenser microphone.
The noise sensor is equipped with a capacitive electret microphone that is sensitive to sound. When sound waves cause the electret film to vibrate, it will lead to a change in capacitance, thereby generating a corresponding tiny voltage. This voltage variation realizes the conversion from sound signals to electrical signals.
