US 9,792,892 B2 · Noise cancellation system

Abstract

Active noise cancellation may be provided by a variety of systems, methods and techniques. General aspects, for example, include an active noise cancellation system, a controller for an active noise cancellation system, and/or a method of generating an anti-noise signal. In one example aspect, an active noise cancellation system for an aircraft In-flight entertainment system may include at least one input device, a processing means, and an output. The input device may be associated with a seat on the aircraft and adapted to receive an input representative of an ambient noise in the vicinity of the seat. The processing means may be adapted to process the input to produce an output signal adapted to reduce the ambient noise in volume associated with the seat. The output may be adapted to transmit an output signal to at least one driver, which is adapted to transmit the output signal to a user.

Dependent claims

An active noise cancellation system for an aircraft In-flight entertainment (IFE) system, the active noise cancellation system comprising:

At least one transducer, on or in a seat on the aircraft, to receive an input representative of an ambient noise at the transducer input;
At least one driver, the driver located on, or part of, a headset and adapted to transmit an output signal to a user;
An output for transmitting an output signal to the driver, and
A processor adapted to process the input to produce an anti-noise signal adapted to reduce the ambient noise at the at least one driver location, the processor further adapted to produce the output signal by superimposing the anti-noise signal and a signal received from the IFE system.
