SV 971A

Class 1 Sound Level Meter

About

The new SV971A Sound Level Meter has been designed for both occupational noise and building acoustics measurements. The Class 1 meter has been equipped with a new measuring microphone offering a LAeq linear measurement range from 27 to 137 dB (140 dB Peak) in a single range! The microphone’s improved design ensures even better long-term stability of microphone sensitivity. The SV 971A uses the new low-power Bluetooth® interface allowing current results to be previewed on a smartphone or tablet as well as controlling measurement Start / Stop. The Assistant application also signals an alarm when set noise limits are exceeded. Along with the new hardware additions, the SV971A Sound Level Meter has been equipped with a new internal program that supports the reverberation time RT 60 measurement and STIPA speech intelligibility measurements, both supported by a mobile application.
