Title: Active airborne noise reduction
Inventor: BRIAN C BECKMAN
IPC: G06N20/00
Filed: 2020-02-06
Abstract: To actively reduce airborne noise including but not limited to noise generated by an aircraft during flight operation.SOLUTION: Noise that is to be emitted by an aircraft 1210 may be predicted by using one or more machine learning systems, algorithms, or techniques. Anti-noise having equal or similar intensity and equal but out-of-phase frequency may be identified and generated based on the predicted noise, thereby reducing or eliminating net effect of the noise. The machine learning systems, algorithm, or technique used to predict such noise may be trained by using emitted sound pressure level observed during operation of the aircraft, and environmental conditions, operational characteristics of the aircraft, or locations of the aircraft during such prior operation. The anti-noise may be identified and generated based on an overall sound profile of the aircraft, or on individual sound emitted by the aircraft by discrete sources.SELECTED DRAWING: Figure 12A
