Building Acoustics

Measurement of acoustic insulation

The SV 977 sound meter can be used to calculate RT60 results, which measure the time it takes for the sound level in a room to decay by 60 decibels after the sound source has stopped. With the support of a mobile application called Assistant, the SV 977 helps the user calculate insulation in accordance with BS EN ISO 16283. During the measurement, the Assistant application allows the user to create a project containing measurements from the source and receiving rooms for different sound source positions. The project and measurement files are saved in the memory of the sound meter for easy reference and analysis.

Environmental noise

Upgrade to a monitoring station

For outdoor noise measurements, the SV 977 can be used inside an IP 65-rated case. The light-weight microphone protection kit can be easily installed on a mast with standard mounting threads, allowing for easy and flexible setup. The case-type monitoring station is equipped with a 4G modem that enables remote communication with the internet. This means you can use your mobile phone or tablet to check the status of the noise monitoring station at any time, thanks to the SvanNET connectivity service.
