TN201A-weighting Digital Sound Level Meter

 動作原理

The working principle of the AUTOOL TN201 A-weighting digital sound level meter involves capturing surrounding sound waves with a built-in high-sensitivity microphone and converting the sound signal into an electrical signal. The device uses an A-weighting filter to process the sound signal, simulating the human ear’s response to different frequencies, thus accurately measuring the noise level. The decibel (dB) value is displayed in real-time on the screen, allowing users to easily monitor the intensity of environmental noise, making it suitable for a wide range of noise monitoring applications.
