Abstract
An audio signal received at a mobile device is processed using a first set of equalization parameters in an acoustic coupling mode of operation, and is processed using a second set of equalization parameters in an inductive coupling mode of operation. The processed audio signal is transmitted to a speaker associated with the mobile device for acoustic coupling to a human ear and/or a hearing aid microphone, or for inductive coupling to a hearing aid telecoil.
