Overview

: A sound level meter is a basic noise measurement instrument. It is an electronic instrument, but different from electronic instruments such as voltmeters. When converting sound signals into electrical signals, the time characteristics of the human ear's response speed to sound waves can be simulated; The frequency characteristics with different sensitivities to high and low frequencies, as well as the intensity characteristics that change the frequency characteristics at different loudness levels. A sound level meter is a specialized electronic instrument.

产品特点

A sound level meter is a basic noise measurement instrument, which is an electronic instrument but different from electronic instruments such as voltmeters. When converting sound signals into electrical signals, the time characteristics of the human ear's response speed to sound waves can be simulated; The frequency characteristics with different sensitivities to high and low frequencies, as well as the intensity characteristics that change the frequency characteristics at different loudness levels. Sound level meter is a special electronic instrument.Has three major characteristics:

one

Low power consumption, can be used for a long time with one battery change

two

Accurate measurement and fast detection speed

three

Compact in size, portable and can be used anytime, anywhere
