It is very important to be in a quiet place during the hearing test so that the ambient sounds do not disturb your test. Before the test begins, you will be prompted to allow the app to access your microphone so that the background noise can be properly evaluated. If you have already turned off the use of the device microphone, you can grant microphone permission at any time by finding the permissions menu in your device settings. Here you need to find the microphone and make sure that the application is allowed to access the microphone.
