HearGuard: Decibel Meter dB

HearGuard turns your iPhone into a simple, honest sound level meter. Measure the noise around you in real time, track your daily noise dose, and stay aware of your hearing health - all on-device.

PROTECT YOUR HEARING BEFORE IT'S TOO LATE

The World Health Organization estimates that over 1 billion young people are at risk of noise-induced hearing loss. It's permanent, painless at first, and largely preventable. HearGuard gives you the awareness you need to act before the damage is done.

• Approximate readings for everyday awareness (not a professional instrument)

DAILY NOISE DOSE

• Noise dose tracking based on the NIOSH 85 dB / 8-hour guideline (3 dB exchange rate)
• Time-at-level breakdown shows how long you spent at each level today
• Health insights tailored to where you spend your time, with cited sources (WHO, NIOSH, CDC)

PREMIUM FEATURES (HearGuard Pro)

YOUR PRIVACY MATTERS

HearGuard processes all audio entirely on your device. We never record, store, or transmit your audio - only sound levels are measured.

HearGuard is not a medical device and does not diagnose, treat, or prevent hearing loss. Sound levels are approximate and can vary between devices. For concerns about your hearing, consult a qualified professional.
