Claim Text:
1. A hearing monitoring system for monitoring hearing loss over a plurality of tests, comprising: an audio test unit configured to output one or more test sounds to an ear of a user during a respective hearing test, the audio test unit being configured to deliver the one or more test sounds at a plurality of test frequencies and at a plurality of stimulus levels; and a hearing test control system configured to display the plurality of test frequencies on a display screen and receive indications of a selection of respective ones of the plurality of test frequencies, the control system, upon receipt of an indication of a selected test frequency, causing the audio test unit to output one or more test sounds at the selected test frequency to an ear at one or more stimulus levels during the respective hearing test, wherein the control system is configured to receive an indication of whether the test sound was heard by the indicated ear at the selected test frequency and, for instances where the test sound was heard, storing the stimulus level for which the test sound was heard for respective hearing tests, wherein the control system is configured to store the highest set of test frequencies for which an indication was received that the test sound was heard by the indicated ear along with a baseline value related to the stimulus level at which the test sound was heard, the highest set of test frequencies for each ear being the sensitive range for ototoxicity for that respective ear for respective hearing tests, wherein the control system is configured to compare baseline values for the sensitive range for ototoxicity obtained during at least one prior hearing tests with those obtained from one or more subsequent hearing tests, and display on a display screen an indication of a change, if any, between prior baseline values and current baseline values for the sensitive range for ototoxicity and/or between a prior sensitive range for ototoxicity and the current sensitive range for ototoxicity.
