A wide soundstage emanating from the dashboard and a dedicated audio program for each seat. With these two concepts, Sennheiser Mobility will introduce two software modules for future in-car audio systems on November 10, 2026. Scenico uses AMBEO technology for spatial audio reproduction. Polifonia is designed to better separate the audio content for each individual seat using headrest speakers.
Scenico with AMBEO for a wide soundstage
The patented Scenico module processes the signals for a group of speakers in the dashboard. According to Sennheiser, this compact array is designed to create a soundstage that subjectively extends beyond the interior. At the same time, the center of the soundstage is intended to be reproduced with stability.
The compact layout gives automakers more flexibility in designing the interior. Depending on the configuration, they can eliminate the need for speakers in the doors. Sennheiser also sees advantages in this approach when it comes to dismantling and recycling the components. The manufacturer cites mid-size vehicles in particular as the primary application area, where space and design requirements play an important role. In larger cars, Scenico is also a viable option for the entertainment system in the second row of seats.
Polifonia separates the listening zones at each seat
Polifonia processes the audio signals for the speakers in the headrests. The module uses noise cancellation to reduce acoustic crosstalk between seats. This allows different audio programs to play simultaneously. For example, the driver can hear navigation prompts and warning messages, while passengers listen to music, make phone calls, or watch a movie.
Both modules are designed for integration by vehicle manufacturers. Sennheiser did not specify a timeline for the first production implementation in its announcement.
