A mobile station () that includes a processor () that selectively disables at least one station component to reduce electromagnetic noise generated by the station in the frequency range below 20 kHz when the mobile station is operated in the hearing aid compatible mode. The component can be, for example, a display (), a light () or a wireless interface (). The processor also can optimize characteristics of audio signals transmitted from the mobile station to the hearing aid for reproduction by the hearing aid. For instance, the processor can selectively adjust filter parameters () and/or a signal gain () applied to audio signals. A user interface () having a soft-key can be provided to cycle through various HAC options.
