1. A method, comprising: outputting, by a device including a processor, a tone corresponding to a currently selected frequency band to a currently selected ear at a signal level of a first predetermined value; adjusting, by the device, the signal level of the outputted tone in a first direction at a granularity level until receiving a first input, wherein the first direction is one of increasing or decreasing, wherein the first input indicates hearing of the outputted tone by a user if the first direction is increasing or the first input indicates not hearing of the outputted tone by the user if the first direction is decreasing, and receiving, by the device, the first inputs adjusting, by the device, the signal level of the outputted tone in a second direction at a finer granularity level than the granularity level in the first direction until receiving a second input, wherein the second direction is opposite the first direction, wherein the second input indicates hearing of the outputted tone by the user if the second direction is increasing or the second input indicates not hearing of the outputted tone by the user if the second direction is decreasing, and receiving, by the device, the second input; repeating, by the device, at least one of the adjusting the signal level of the outputted tone in the first direction and the receiving the first input or the adjusting the signal level of the outputted tone in the second direction and the receiving the second input until a predetermined number of changes in direction has occurred, wherein at each change in direction the granularity level is made finer than an immediately preceding direction; and recording, by the device, a current signal level of the outputted tone for the currently selected frequency band and the currently selected ear in a hearing sensitivity testing results record. |
