Abstract
A system for providing audio output. The system includes a device, e.g. a mobile phone connectable to one or more earphones. The device includes a computing platform having a processor; an audio unit configured to generate one or more output signals of arbitrary amplitude to the earphone(s); and at least one microphone configured to record the ambient power level during signal output. The user indicates his/her hearing of the output signals whereby a proportionality constant is recorded for each frequency of the output signals. The processor is configured to: analyze the proportionality constant for each frequency of one or more feedback signals from the earphone(s) to yield calibration data; adjust the amplitude or frequency based on the calibration data; generate one or more audiograms resulting from a hearing test; and adjust the device power level according to the received one or more audiograms.
