Class 1 Noise Monitoring Station
SV307A Noise monitoring station is the newest version of the all-in-one noise monitoring station based on a patented MEMS microphones technology covered by the life-time warranty. The SV307A Noise monitoring station has been designed for the permanent noise monitoring in all weather conditions – it uses smart solutions to control the internal temperature and to detect any hardware failures. The new housing is made of strengthen material that protects internal electronics: class 1 sound level meter with 4G and GPS modems. The SV307A Noise monitoring station measures noise levels, statistics and spectra together with audio files that can be triggered on level or time. The advanced triggering provides also possibility of the noise prediction to alarm the user before certain noise levels are reached. Moreover, with the SvanNET Service it is possible to connect to SV 307A to listen the live noise from the microphone!
Noise Monitor with MEMS microphone Approved by PTB
In 2022, the Physikalisch-Technische Bundesanstalt (PTB) has granted the world’s first Class 1 Sound Level Meter with MEMS microphone approval to SV 307A Noise Monitor. It is an important turning point in the history of MEMS microphones in environmental sound monitoring.
