Claim Text:
1. A method for monitoring or testing the hearing of a user, the method comprising: presenting a plurality of test frequencies for selection by a user through a display or acoustically; receiving indications of respective selections of test frequencies by the user, including indications of a right ear or a left ear that is to be tested at the respective selected test frequencies; causing an audio test unit to output one or more test sounds at respective ones of the selected test frequencies to the indicated ear, the one or more test sounds being output at one or more stimulus levels; receiving an indication of whether the test sound was heard by the indicated ear at the selected test frequencies and, for instances where the test sound was heard, storing the stimulus level for which the test sound was heard; storing the highest set of test frequencies for which an indication was received that the test sound was heard by the indicated ear, the highest set of test frequencies for each ear being the sensitive range for ototoxicity for that respective ear; storing a baseline value for each frequency in the sensitive range for ototoxicity for each ear, the baseline value being based on the stimulus level at which the indication that the test sound was heard was received; monitoring the sensitive range for ototoxicity for each ear by performing one or more subsequent hearing tests and comparing the baseline values for the respective sensitive range for ototoxicity with stimulus levels obtained from additional hearing tests; and calculating whether a change in the baseline values has occurred in the one or more subsequent hearing tests.
