Techniques for providing a hearing aid compatible mode of transmission for a mobile station in a radio communication system are described. By adjusting a transmission envelope of a mobile station which transmits information in a burst fashion, harmonics which would normally be introduced into a hearing aid placed in close proximity with the mobile station are avoided. The modified transmission envelope provides a more gradual up and down-ramping of power to the transmitter to avoid introducing harmonics in the audio frequencies. This service can be provided at a system level in a manner which will avoid unnecessarily reducing system capacity by, for example, authenticating a user's identity, his or her subscription to this mode of operation, the mobile station's ability to modify the transmission envelope according to the present invention, and the user's desire to actually implement the hearing aid compatible mode of operation.
