Abstract:
Method and apparatus are disclosed for active sound desensitization to tonal noise in a vehicle. An example vehicle includes an electric motor, a microphone, speakers, and an active sound desensitizer. The active sound desensitizer (a) randomizes channels of the speakers based on multiple uncorrelated broadband sound profiles, (b) determine upper and lower frequency band limits for a band-limited filter, (c) generate a desensitizing sound based on the upper and lower frequency band limits and the randomized channels, and (d) broadcast the desensitizing sound via the speakers.
