Spatial Noise Cancelling
By reducing road noise caused by tire friction and surface vibrations, in-car conversations become clearer and entertainment such as music can be enjoyed more comfortably.
Our noise-canceling system uses speakers built into each seat, ensuring effective performance for every passenger.
By generating sound waves with reverse phase to the in-cabin noise based on the vehicle’s driving conditions and playing them through the seat speakers, road noise is effectively reduced.
Personalized Sonic Environment
360 Auto Acoustics Personal enhances the realism of music and delivers clearer audio directly to your ears by creating a personalized sound field around each occupant using seat speakers embedded in the headrest or backrest.
Furthermore, by integrating Sony’s signal processing technology, 360 Spatial Sound Technologies—widely used across its audio product lineup—into in-car audio systems, it enables a variety of unprecedented acoustic experiences.
Sound Experience Realized by Seat Speakers
Conventional System
360 Auto Acoustics Personal
Traditional vehicle audio has typically provided a sound field centered around a single seat, such as the driver or front passenger. However, with 360 Auto Acoustics Personal, speakers embedded in each seat make it possible to create a sound field centered around each occupant, allowing everyone on board to equally enjoy music in the best possible acoustic environment.
Various Features of 360 Auto Acoustics Personal
Thanks to independently controlled speaker systems in each seat, passengers can enjoy shared experiences together—or choose different content individually—offering new ways to spend time in the car and flexibly responding to a variety of needs.
Make Everyone’s Wishes Come True
Enjoy your favorite content with your preferred settings in a sound environment tailored just for you.
Lightweight, Efficient, and Space-Saving Solution
Enables multi-channel playback with a more compact speaker setup than conventional solutions.
Driver-exclusive All-directional Assistive Audio
Based on information from the vehicle, directional alerts such as warning sounds or navigation steering instructions can be delivered exclusively to the driver, while minimizing any impact on the entertainment experience of other passengers.
Versatile Sound Field Reproduction
Native playback of various audio formats, from 2-channel stereo to multi-channel surround, is supported using just a single pair of left and right speakers (availability of features may vary depending on region and service). In addition, stereo sources can also be upmixed for 3D playback.
Immersive 3D Sound
360 Auto Acoustics Cabin is a technology that creates a three-dimensional sound field within the vehicle cabin, powered by Sony’s proprietary deep neural network-based sound source separation and spatial synthesis technology (Monopole Synthesis). Whether the content comes from stereo sources or immersive formats such as 360 Reality Audio or Dolby Atmos®, it delivers a high-quality 3D audio experience with exceptional realism and immersion.
Dolby Atmos is a registered trademark of Dolby Laboratories Licensing Corporation.
Sound Field That Transcends Cabin Size
By creating virtual speakers outside the cabin, it forms a large-scale surround sound field.
Uniform Sweet Spot Across All Seats
A wide and stable listening sweet spot that covers the entire cabin delivers a high-quality 3D audio experience to all occupants.
3D Experience with Stereo Sources
By upmixing 2-channel stereo audio into 3D, it creates a spatial sound environment with enhanced realism and immersion.
360 Reality Audio and Dolby Atmos Playback Support
Native playback of 360 Reality Audio and Dolby Atmos content is supported (availability of features may vary depending on region and service).
Expertly Crafted Audio Performance
In addition to incorporating a range of advanced audio technologies, experienced sound engineers are involved in the acoustic design from the early stages of vehicle development. By tuning the sound to suit the unique cabin environment—including structural layout, interior materials, and seat fabrics—we achieve an ideal acoustic design.
Our speakers, which serve as the final output for sound, are not only custom-designed for their installation locations and frequency ranges, but many also feature Sony’s proprietary diaphragm materials. This enables faithful reproduction of all audio sources, including high-resolution content.
Sony’s Proprietary High-quality Speaker Diaphragms
Multilayer Carbon Reinforced Diaphragm, Cast-fiber Carbon Composite Diaphragm, and Lightweight Rigid Cellular Diaphragm are all thin and lightweight, combining two essential properties for speaker diaphragms—high rigidity and high internal loss. This enables a wider frequency response with minimal distortion.
Multilayer Carbon Reinforced Diaphragm
The Multilayer Carbon Reinforced Diaphragm adopts a sandwich structure, in which upper and lower layers of carbon fiber reinforced thermoplastic material enclose a middle layer of closed-cell foam core. This design achieves the rare combination of light weight, high rigidity, and high internal loss—properties that are typically contradictory in nature. As a result, it delivers flat frequency response across broad spectral coverage, faithfully reproducing the full richness of the original audio content.
Cast-fiber Carbon Composite Diaphragm
The Cast-fiber Carbon Composite Diaphragm, produced through a precision papermaking (=pulping) process using high-elasticity carbon fiber and polypropylene fiber, offers greater rigidity compared to conventional diaphragm materials. This enables a wider frequency response and smooth, natural sound reproduction.
Lightweight Rigid Cellular Diaphragm
The Lightweight Rigid Cellular Diaphragm , featured across our range of audio products, combines low mass, high rigidity, and optimal internal loss—delivering powerful, clear sound across a wide frequency range.
High-Resolution Audio Compatible Class-D Amplifier
Built on Sony’s decades of expertise in digital amplifier technology, this compact yet uncompromising multi-channel amplifier delivers exceptional audio fidelity. Every detail of the music is reproduced with stunning clarity, thanks to carefully selected components and optimized circuit design. The result is a powerful, lifelike sound experience—just like having the artist perform right in front of you.
