MagyarYamaha develops automotive sound system utilizing Music:AI leveraging its deep musical instrument and sound system experience to optimize sound quality
Yamaha has developed Music:AI, an artificial intelligence technology that leverages the company’s extensive musical instrument and sound system development experience to automatically optimize its automobile sound system.
Automobiles are acoustically challenging spaces for audio systems. Noises intrude from outside (e.g. other nearby vehicles, alarms and honks, tire noise, etc.) as well as from the vehicle itself (e.g. air conditioner, fans, wipers, engine, motors, etc.). The complex shape of the interior using hard and soft surfaces reflect and absorb sound from speakers.
Traditionally, automobile sound system designers place microphones in the position of each passenger, then manually tune the speaker outputs to create the best sound. This works best when the car is turned off and stationary, but the moment the car is driven, ever changing noises corrupt the tuning.
The hearing ability and sound tuning preference also varies among individuals. For example, older listeners often cannot hear the highest frequencies due to aging or long-term damage from listening to excessively loud music.
Yamaha targets these challenges with Music:AI for Cabin, Music, and Person. Music:AI for Cabin quickly optimizes the sound system for each car cabin, automatically finding the best tuning parameters. Music:AI for Music monitors the cabin in real-time to automatically optimize the reproduction and volume of music. Music:AI for Person allows each individual to tell the system what sounds best to their ears, automatically compensating for subjective preferences.
The company recently entered the automotive market, and its current, non-AI system is installed in Japan’s most prestigious model, the Toyota Crown. Music:AI will be available in its high-end car amplifiers for integration by automakers in 2025.
Drivers enjoying their non-AI sound systems might want to clean their cabin air with an air purifier (like this at Amazon) to protect their ear and brain health.

Yamaha Corporation (hereinafter referred to as "Yamaha") has developed "Music:AI®," a technology that uses AI to optimize cabin acoustics and provide a new music experience. This technology will be installed in high-end amplifiers under development for the start of mass production in 2025 and will be sold to automakers in Japan and overseas.
Against the backdrop of technological innovation, the interior space of automobiles is evolving into a "second living" where you can enjoy a variety of acoustic entertainment. As a result, there is a need for advanced optimizations that cannot be handled by conventional tuning technologies, such as rapid adjustment of increasingly complex sound systems, application of acoustic characteristics suitable for each type of content such as music and movies, and realization of personalized sound quality. We propose an unprecedented music experience with "Music:AI®" that has learned the skills and sensibilities of outstanding tuning engineers.
Music: The three technologies that make up AI® for Cabin
Acoustic tuning is essential to adapt to the acoustic characteristics of the cabin space for each vehicle model. By utilizing AI, we can derive the optimal solution from a myriad of acoustic parameter sets in a short time, and pursue further sound quality that has not been possible until now.
for Music
In order to express the charm of the song to the fullest, it is necessary to have the optimal acoustic parameters for each song. By utilizing AI, the sound you are listening to is optimized in real time. It also contributes to safe driving by eliminating the need for the driver to adjust the sound quality.
for Person
When it comes to balancing between high and low tones, listeners have a wide variety of preferences. Through dialogue, AI provides optimal acoustic parameters for each individual. It's a new approach to discovering your favorite sounds that you haven't noticed before.
