noise meterA noise meter, also known as a sound level meter, noise detector, decibel meter, etc., was the most basic noise measurement instrument. It was an electronic instrument, but it was different from objective electronic instruments such as a voltage meter. When converting sound signals into electrical signals, it could simulate the time characteristics of the human ear's response speed to sound waves. It had the characteristics of different sensitivity and the intensity characteristics of different loudness. It was a subjective electronic instrument. It measures the sound level and frequency of environmental noise to assess the impact of noise on human health and the environment. Common noise meters such as the VC824 digital noise meter have a measurement range of 30 - 130dBA, 35 - 130 dCC, a storage environment humidity of 10 - 80%RH,and a use environment humidity of 10 - 70%RH.1
