The HS5670A Integral Average Sound Level Meter is a precision acoustic measurement instrument independently developed through innovation. It features a streamlined design, a large measurement dynamic range, a large screen LCD digital display, and automatic measurement and storage of various data. The built-in filter can automatically perform 1/3 and 1/1 spectral analysis, meeting the requirements of the new national noise measurement standards. Through the RS232C serial port, the matching printer can automatically print out the measurement results and spectra. The measurement data can be output and transmitted to the computer through the interface communication cable, achieving real-time communication output of sound pressure level Lp and effective measurement and calculation of aircraft noise level Lepn. The HS5670A integral average sound level meter is easy to operate, convenient to use, and highly reliable. It can be widely used for measuring industrial noise and environmental noise in various machines, vehicles, ships, electrical appliances, etc. It is suitable for sound testing fields in factories, enterprises, environmental protection, labor health, transportation, teaching, scientific research and other departments.
