Safe & Comfortable Cabin

Automobiles are not only a means of transportation, but also a living space where people spend their time.
To ensure that this space is comfortable and safe at all times, Asahi Kasei Microdevices (AKM) has provided unique audio & voice processor products and software for more than 15 years.
Here, we introduce the backgrounds and reasons for the popularity of our products in this demanding automotive field.

Solutions

Road Noise Cancellation technology is reducing the noise that is generated from road induced vibrations. This is performed by composied a secondary sound field using acceleration signals as inputs and processing these signals in real-time with low-latency computational efforts. AKM  provides  low-latency  ADCs  that  enables  fast  signal  transmission  to  the  AKM  DSPs  that  host  the  Silentium  Road  Noise  Cancellation  libraries. As a result, the total combined SW/HW system becomes a unique solution for low-latency automotive ANC (Active Noise Cancellation) applications.
