Java/Android application for detecting hearing loss

Sammanfattning: An Android mobile application has been created with a standard audiometry test and a specific psychoacoustic (temporal masking) test to measure the user’s hearing profile and the hidden hearing loss. The application performs these tests over Bluetooth communication with a specific headphone (Sony WH-1000X M3). The audiometry test is following the standards. The audiometry will be playing tones in different frequencies (1KHz, 2KHz, 3KHz, 4KHz, 6KHz, 8KHz, 500Hz, 250Hz). The user is responding to the tone by pressing or releasing a touch button on the phone screen. The temporal masking plays a noise and a ftm (Functional tone management) tone in three different frequencies (500Hz, 2KHz, 4KHz). The noise will have the same intensity through the test on 80dB but the ftm (Functional tone management) tone will change the intensity depending on the input from the user. The user should respond to the ftm (Functional tone management) tone by pressing or releasing a touch button on the phone screen. The application is then sending the results over Bluetooth to the specific headphones over serial communication (SPP profile). The test result will then be used for tuning the sound coding parameters in the connected headphones according to the user’s individual hearing profile. The design of the headphone is not part of this thesis work but will be done in the future.
