The type 1 noise meter uses a microphone offering a linear measurement from 27 to 140 dB in a single range. For ease of use the sound level meter uses dedicated mobile applications, that support sound measurements as well as RT60 and STIPA.

SV 977 Class 1 Sound and Vibration Level Meter

The SV 977 is a Class 1 Sound and Vibration meter designed for building acoustics, occupational noise and environmental noise measurements. A unique feature of the SV 977 is ultrasound measurement band up to 40 kHz. The ultrasound band is normally considered as the frequency range above 20 kHz. Ultrasound is used in a number of industrial processes such as cleaning, drilling or welding as well as hospitals for medical procedures.
