Abstract:
A sound control module is configured to, based on a type of road over which a vehicle is traveling and a smoothness of the road, at least one of: determine a first frequency and a first increase at which to increase a first magnitude of a microphone signal; and determine a second frequency and a first decrease at which to decrease a second magnitude of the microphone signal. An audio driver module is configured to: receive the microphone signal from a microphone of the vehicle; generate an adjusted microphone signal by at least one of: increasing the first magnitude of the microphone signal at the first frequency based on the first increase; and decreasing the second magnitude of the microphone signal at the second frequency based on the first decrease; and apply power to a speaker of the vehicle based on the adjusted microphone signal.
