Field Sound Transmission Loss Testing of Building Elements using Sound intensity

SINUS Soundbook + SABURAI Software + Sound Map Option + Sound Intensity Probe

 

Sound transmission loss values may be determined in-situ using a Soundbook/Apollo Data Acquisition System, basic SAMURAI Software Sound Map Option, power amplifier, sound source and a sound intensity probe, in accordance with ISO 717/1

R´w may be determined from sound intensity measurements for airborne sound insulation rating. The airborne insulation value, in decibels, is specified from the reference curve at 500 Hz after shifting it according to the ISO 717/1.

The SoundMap Software Option may also be used to detect sound leakage locations.

Typical results displays are shown below for both applications:
