In-car personal sound zones

A new in-cabin technology lets drivers and passengers listen to what they want when travelling together, according to an audio-device company.

The technology, Individual Sound Zones (ISZ), developed by Harman, intends to reduce noise clutter from a shared vehicle be it hands-free calling, music, audio books or games on mobile devices, allowing people to be selective with what they hear.

“Individual Sound Zones and the HALOsonic technology suite enable automakers to offer enhanced experiences to passengers, as well as imagine new possibilities as the car itself continues to evolve in use beyond the traditional ‘people mover’,” said Michael Mauser, president of Lifestyle Division at Harman.

ISZ creates sonic zones that maximise the direction of the sound coming from the speaker and minimise crosstalk in and between the zones in a vehicle. Other sounds won’t be eliminated completely, but optimised for the current mode of listening.

“With HARMAN’s science-based architecture and acoustic precision, we’re pushing the barriers of sound and creating the ultimate personalised experience throughout the vehicle cabin,” Mauser said.

ISZ uses a vehicle’s existing audio system speakers, which incorporates headrest speakers equipped with micro-speaker technology along with thin and flat Electro Dynamic Planar Loudspeakers in the vehicle ceiling.

The technology can be integrated into any HARMAN in-car audio system and is available to all automakers.
