Customized audio modification tool
A method and system for providing a customized configuration of settings for an audio processor. The customized configuration is determined for a user based on results of a hearing test. The test may be provided by the system or another system. The customized configuration includes an increase or decrease to an intensity level of one or more frequency bands of one or more channels (e.g., a left and right) to compensate for a decreased hearing threshold level experienced by the user (e.g., as indicated by the hearing test results). The settings may be further adjusted based on an application of one or more equal-loudness contours representing varying sensitivity of the human ear to different frequencies. When audio is played by an application including or in communication with the audio processor, the audio is adjusted based on the customized configuration and the user is provided with an improved listening experience.
