SV 971A Class 1 Sound Level Meter

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 with Start/Stop functionality. The Building Acoustics Assistant Application also signals an alarm when set noise limits are exceeded. Along with the new hardware additions, the SV 971A 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.
