A method for feedforward noise cancellation in an enclosed space within a structure is provided. The method comprises placing a microphone array inside an inner surface of the enclosed space and conducting modal testing on an outside surface of the enclosed space, wherein the modal testing comprises multiple incoherent noise sources corresponding to locations of microphones in the microphone array. Noise generated by the modal testing is processed to create a number of acoustic mathematical models of the enclosed space. In response to incoherent noise within the enclosed space, a noise canceling signal is generated according to an output of the mathematical models.

20230012052 · 2023-01-12 ·

A device and a method for detecting voice of a user of an intra-aural device. The intra-aural device has an in-ear microphone adapted to be in fluid communication with an outer-ear ear canal of the user occluded from an environment outside the ear. A signal provided by the in-ear microphone is obtained to determine an acquired voice indicator signal, and a voice produced by the user is detecting by comparing the acquired voice indicator signal with a corresponding threshold value, upon the acquired voice indicator signal being larger than the corresponding threshold value. Although the method also reduces any voice interference coming from a non-user, the results are improved when the non-user voice is captured from an outer-ear microphone of the intra-aural device.
