Abstract
Different hearing impairment compensation parameters are stored in a searchable attribute database indexed by the telephone numbers of hearing impaired users. Calls made to or from the stored telephone numbers have incoming voice samples redirected to signal processing resources that perform customized hearing compensation. The compensation parameters are downloaded from the attribute database to the chosen signal processing resource at call setup time. The signal processing resource then compensates the audio signals of the telephone call for specific user hearing impairment using the downloaded compensation parameters.
