Support for the creation and setup of an emergency sound system in compliance with European standards
For the designer and the installer - before installation
Electroacoustic study - Using the EASE software, the 3D environment is rebuilt and the system performance is simulated in terms of sound pressure level and speech intelligibility in order to verify compliance with rules.
For the installer or maintenance technician
Acoustic performance measurements - The speech intelligibility (STIPA and / or STI indices) and sound pressure are measured over the listening area. Then a technical report is prepared containing the results of the measurements and any recommendations if the system shows non-compliances from an electroacoustic point of view. In case the performance of the system is strongly conditioned by environmental acoustics, reverberation times can be measured.
