Sony patents noise cancellation that adjusts when sudden sounds hit

Sony describes a system that uses two different sensors to monitor vibrations and sounds. If one sensor detects a sudden loud noise, the system automatically lowers the power sent to the noise-canceling component to prevent interference.

Why it mattersThis approach could help headphones or car seats stay stable and comfortable when unexpected loud noises occur, rather than reacting too strongly.

In the filing’s own words

The present disclosure relates to a noise suppressing apparatus, a noise suppression method, and a program that make it possible to appropriately reduce noise. When a sudden sound is sensed on the basis of a sensor signal of a sensor in an FF-scheme NC apparatus, a drive signal to be supplied to an actuator in an FB-scheme NC apparatus is reduced. This can be applied to an NC apparatus.

What exactly they claim (claim 1)

1. A noise suppressing apparatus comprising: a first processing section that executes a process to reduce noise at a control point by generating and outputting a sound to cancel the noise or a vibration to excite a noise-source vibrating object, on a basis of a first sensor signal including an acceleration of the object; and a second processing section that executes a process to reduce noise at a control point by generating and outputting a sound to cancel the noise or a vibration to excite a noise-source vibrating object, on a basis of a second sensor signal that is different from the first sensor signal and includes an acceleration of the object, wherein, when a sudden sound is sensed on the basis of the first sensor signal, a drive signal at the second processing section is adjusted.
