What makes AKM different ?
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.
