HEAD acoustics Launches Acoustic Environment for Realistic Noise and Reverberation 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.
