• This app does not provide medical advice, diagnosis, or treatment. Consult a physician if symptoms persist or worsen.

# Main features

# White Noise Player

Use the White Noise Player to create a steady sound environment for focus, relaxation, or rest.

What you can do:

• Choose a preset noise profile.
• Adjust the frequency equalizer (multi-band).
• Control master volume and per-ear volume (left/right/all).
• Save your settings as custom presets.
• Use background playback when needed.

Tips:

• Start with low volume and increase gradually.
• If left and right ear settings differ, adjusting the "All" target may overwrite both ears.

# Tinnitus Matching

Tinnitus Matching lets you play a test tone to find a frequency that is close to what you hear.

What you can do:

• Adjust frequency and volume.
• Try different tone types (waveforms) to find the closest match.
• Once you confirm a frequency, you can apply it to generate or tune your white noise settings.

Tips:

• Try in a quiet environment.
• Many tinnitus frequencies are commonly in the 2–8 kHz range, but results vary.

# Background playback (iOS)

Soothing Sound supports background audio so playback can continue when you leave the app or lock the screen.

How to stop playback:

• In the app: pause/stop playback from the controls.
• From iOS: open Control Center and stop audio from the Now Playing controls.
