Simulate room reverberation with 3PASS reverb
HEAD acoustics launches world´s first acoustic environment for realistic measurements
Users of mobile phones, voice-operated smart home devices or hands-free terminals have to deal with different background noises and room reverberation that impair their user experience. Therefore, realistic performance tests of communication devices do not only need to consider background noise but also reverberation. HEAD acoustics launches 3PASS reverb for this purpose, a software option for its background noise simulation systems 3PASS lab and 3PASS flex. 3PASS reverb is capable of simulating realistic room reverberation.
Realistic reproduction in the laboratory
With 3PASS reverb, the audio experts of HEAD acoustics have developed a methodology that enables developers and manufacturers to reproduce different room characteristics like realistic reverberation in the laboratory. The software simulates the reverberation of the room by applying the previously recorded impulse responses to any audio signal in real time. While an artificial head measurement system plays back the direct sound signal, the background noise system covers playback of the reverberation components based on the impulse response from the original room. Exemplary impulse responses from various rooms are included as standard in 3PASS reverb.
The methodology invented by HEAD acoustics has been successfully approved as ETSI standard TS 103 557 in December 2018.
