Patent abstract
A method of detecting a change in hearing of a user includes providing a sound generating device for providing both a content audio signal and a hearing test audio signal. The sound generating device is used to provide hearing test audio sounds of different loudnesses around a threshold of hearing of the user. None of these sounds is calibrated to a pre-specified decibel level. A first threshold of hearing is determined at a first time and a second threshold of hearing is determined at a second time. The first threshold of hearing is compared with the second threshold of hearing.
