About this app

Sound Lab is your pocket speaker toolkit — use calibrated sound and vibration to help push water out of the speaker, loosen dust from the grille, and test how clearly your phone or earbuds actually play.

Trapped water after a splash? Muffled, crackly audio? Open Sound Lab, pick a mode, and let real, tuned frequencies do the work — then score your speaker's clarity and fine-tune any tone you like.

KEY FEATURES

Clean
- Water Eject: a 165 Hz drainage wave designed to help force trapped water out of the speaker.
- Dust Blast: a 400 Hz pulsing burst that helps shake dust and lint loose from the grille.
- Earbud Clean: a gentler wave tuned specifically for earbuds.
- Vibration Shake: motor vibration plus a low tone to help dislodge grime.
- Air Blast: a powerful white-noise gust for a deep clean.

Test & score
- Speaker Health Check: play a reference tone and score your speaker's clarity.
- Sound Check: quick clarity test with a clean reference tone.
- Stereo Test: play a tone on the left or right channel to check each side.

Tone Studio
- Dial any frequency and pick a waveform (sine, square, triangle, sawtooth).
- Handy presets for water, dust, deep, high and ultrasonic tones.

Noise machine
- White, Pink and Brown noise beds for focus, sleep or relaxation.
- Optional sleep timer to auto-stop playback.

More sound tools
- Hearing Test: find the highest frequency you can still hear (for fun, not a medical test).
- Anti-Mosquito: a high-frequency ultrasonic tone.

WHO IT'S FOR
Anyone who got water in a speaker, hears muffled audio, or just likes testing and tuning sound on their phone, tablet or earbuds.

IMPORTANT
Sound Lab uses audio frequencies and vibration to help expel water and dust. It works with your device's own speaker — it does not open, physically repair or guarantee repair of hardware, and results vary by device. For heavy water damage, seek professional service.
The Hearing Test and Anti-Mosquito tones are for entertainment only and are not medical or diagnostic tools. Keep the volume moderate to protect your hearing.

FREE & PREMIUM
- Free to download and use, supported by ads.
- Optional Premium removes ads. Weekly and monthly plans auto-renew unless canceled at least 24 hours before the period ends; a Lifetime option is a one-time purchase. Manage or cancel anytime in your Google Play account settings.
