## What is Sound Oasis BST?

Sound Oasis® is the world leader in sound therapy systems. We take tinnitus therapy seriously and it is our hope that this application will provide relief for your tinnitus symptoms. This app was designed to complement our BST-400 Stereo Sound Therapy System to provide our military service men and women with even greater tinnitus relief at home or while traveling.

This app provides the following features:
- 25 free “made for tinnitus therapy” sounds, with 10 of them being stereo sounds for greater sound realism.
- A 12-band audio equalizer which allows you to tune the frequency of each sound on this app. This will allow you to customize the sound to better suit your particular tinnitus frequency with the goal of greater hearing comfort as you sleep and relax.
- A white noise overlay sound that you can add to any sound track on this APP.
- Information on how Sound Oasis and other resources can help you manage tinnitus more effectively.

How Does This APP Work?
The sounds in this app can be an effective tool to manage your tinnitus using sound therapy and sound masking to make tinnitus symptoms less noticeable. This masking effect can be particularly effective at night when the surrounding environment is quieter. By listening to pleasant sounds, particularly sounds close to the frequency level of your tinnitus symptoms, your brain will predominantly hear the pleasant sound instead of the annoying tinnitus noise.
