The Sound Insulation Option extends the XL3 for building acoustic applications. The instrument measures the sound pressure level in the sending and receiving room and the reverberation time. All data is aggregated in accordance with the standard and the sound insulation results prompted on the display on-site. This forms the XL3 into a Building Acoustics Analyzer designed for professionals.
