This app is free and no Ads. It can testing the both ear hearing level by variable pure tone sound and then the result is analyzed by protocol.
Also it suggest the suspicious condition of your hearing status.
This test have some limitation - this test can not calculate absolute sound level caused by
1. Noisy environment
2. Maximum volume of device
3. Quality of earphone.
So I use the comparison of the relative output - The difference between right and left
results and also low and high tone of each ear. If your result is abnormal, I recommend that you visit ENT clinic.
Please use this app for screening test of hearing.
