MWC 2019: HEAD acoustics exhibits its next generation measurement technology for mobile phones, IoT devices and headphones
From 25 to 28 February 2019, HEAD acoustics will be exhibiting its comprehensive solutions for optimizing voice and audio quality at the Mobile World Congress (MWC) in Barcelona. The company, which is headquartered in Herzogenrath, Germany, will introduce 3PASS reverb, the new option for simulating room reverberation, to a large audience for the first time in Hall 7, Stand 7J65. The experts on-site show next generation measurement technology, in order to test super-wideband- and fullband-capable mobile phones, voice-controlled IoT devices and ANC headphones.
World's first acoustic environment for realistic measurements
3PASS reverb is the new software option for the background noise simulation systems 3PASS lab and 3PASS flex. It enables manufacturers of mobile phones and other modern communication devices to conduct realistic performance tests and to reproduce acoustic room characteristics like reverberation in the laboratory. 3PASS reverb simulates the reverberation of the room by applying the previously recorded impulse responses to any audio signal in real time. While an artificial head measuring 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.
Evaluate communication quality of voice-controlled IoT devices
HEAD acoustics will also present HQS-SmartHome, the latest database for the ACQUA analysis system. HQS-SmartHome offers efficient test series to evaluate the communication and audio quality of voice-controlled IoT devices like smart speakers. The implemented tests take realistic background noise and reverberation, multiple talkers and directivity measurements into account. In addition, HQS-SmartHome contains common electroacoustic tests like echo, frequency response, delay and distortion.
Testing ANC performance of headphones
Another highlight at MWC are live measurements of ANC headphones. For this purpose, HEAD acoustics has developed the HQS-Audio database. Among electroacoustic measurements like signal-to-noise ratio, total harmonic distortion including noise, and various test signals (e.g. realistic speech signals, logarithmic sine sweeps) the fully automated ACQUA test sequences provide performance tests of passive noise isolation and active noise cancellation. HQS-Audio allows headphone manufacturers comprehensive and targeted tests of the audio performance of their devices.
