Harman, the audio and infotainment systems company, has created a new in-cabin technology that enables drivers and passengers to create sonic zones so that all occupants in the car can hear only what they want to hear.

Harman calls this new technology ‘Individual Sound Zones’. The company says that navigation prompts and phone calls maybe important for drivers, but they could cause nothing more than disturbance for the passengers. Games, audio books and digital videos for one passenger can ruin the in-car experience for the others. Enjoyable sound for one passenger can be ‘sonic clutter’ for the other.

The new technology can help reduce this clutter and ensure that all occupants in the car hear only what they want to. The technology utilizes a car’s existing audio system speakers with addition of headrest speakers equipped with ‘micro speaker technology’ and thin and flat ‘Electro Dynamic Planar Loudspeakers’ in the vehicle ceiling.

ISZ is an acoustic design and digital signal processing that has been specifically adjusted to the cabin and speakers such that it will temper the signals from other sound zones. The signals from other zones are tempered, regardless of whether they are voice, music or other noises. The passengers can activate and control their own sound zone.

HARMAN’s Individual Sound Zones (ISZ) is a new in-cabin technology that enables drivers and passengers to create sonic zones, ensuring that all occupants only hear what matters to them

While there are many different sounds generated in-vehicle, not all of these sounds are relevant to all passengers. Today’s explosion of portable electronics and in-vehicle technologies like navigation, hands free calling and Bluetooth connections have dramatically altered our driving habits and in-cabin experience. Navigation prompts and phone calls are important for drivers, but interrupt the music for passengers. Games, audio books and digital videos for one passenger result in a cabin filled with sonic clutter for all. Harman’s new ISZ technology can help reduce that clutter, ensuring that all occupants in the vehicle hear only what matters to them.

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

ISZ is an innovative acoustic design and complementary digital signal processing that maximizes speaker directivity and minimizes crosstalk in and between the zones in a vehicle for a more personalized in-cabin experience. ISZ does not eliminate all sound signals, but tunes the vehicle to ensure passengers audio experience is optimized for their location in the vehicle and current mode of listening.

ISZ utilizes a vehicle’s existing audio system speakers with the addition of headrest speakers equipped with micro speaker technology, along with thin and flat Electro Dynamic Planar Loudspeakers in the vehicle ceiling. The digital signal processing has been specifically adjusted to the vehicle cabin and speakers such that it will temper the signals from other zones, regardless of whether they are music, voice or other noises. Each passenger can activate and control their “zone.” Passengers can still hear other sounds in the cabin, but those sounds are controlled in a way that limits the interruptions and distractions to each passenger’s own sound experience. The configuration can be customized based on the cabin design and layout of vehicles, as well as type of vehicle (i.e. sedan vs. minivan).

Individual Sound Zones can be integrated into any HARMAN in-car audio system via the amplifier, providing automakers limitless possibilities to further enhance in-car listening experiences. It is available now to all automakers.
