Walking into Huawei’s Shanghai Acoustics R&D Centre, I expected a standard facility tour. What I encountered instead was a comprehensive automotive sound engineering operation that challenges the established order of in-car audio systems.
The facility, which Huawei has developed since beginning serious audio research investments in 2012, houses three distinct testing environments: a fully anechoic chamber measuring 4.8x4x4 metres, a larger semi-anechoic room spanning 14x12x5 metres with a reflective floor, and a dedicated listening room configured in a 9.1.6 layout. Photography wasn’t permitted due to proprietary technology concerns, but the technical specifications tell their own story.
The challenge of in-car audio
Goller, whose background includes positions at Gamut Audio, Bang & Olufsen, and Harman International, oversees what Huawei calls “master-tuning methodology” – a process that begins with objective acoustic measurements but relies heavily on psychoacoustic principles for final voicing.
Speaking in the listening room during the first agenda of the tour, Goller outlined Huawei’s development philosophy: the aim is to faithfully reproduce recordings as artists intended them to be heard, creating what he described as a “phantom effect” that transports listeners to the original recording environment. This requires combining scientific acoustic measurement with artistic tuning expertise and purpose-built hardware.
The technical process, he explained, starts with objective measurements – frequency response curves, phase relationships, timing behaviour, and distortion characteristics. These establish the performance boundaries. From there, extensive subjective listening sessions refine the voicing using psychoacoustic principles to compensate for the cabin’s inherent acoustic challenges: asymmetry, close-range reflections, and bass loading.
The goal is to work within these constraints while remaining faithful to the source material.
The HUAWEI SOUND ULTIMATE Series
The tangible result of this research is the HUAWEI SOUND ULTIMATE Series, the tech giant’s most luxurious audio system to date, currently deployed in the Maextro S800 luxury electric sedan. The system comprises 43 speakers driven by dual amplifiers delivering 2,920 watts total power.
What Huawei terms an “industry-first seat-specific 4D immersive surround sound experience” includes rear 4D exciters that synchronise with music and video content, adding tactile feedback to the auditory experience.
The hardware innovations are specific rather than generic. The Tangential Force Woofer rotates conventional door-woofer geometry by 90 degrees, reducing panel resonance while extending bass response. A patented dual-diaphragm subwoofer leverages the cabin volume itself rather than being constrained by traditional enclosure…
