Why It Matters:
Noise-induced hearing loss is permanent. It builds gradually from exposure you may not notice. Decibel Meter tracks what your ears cannot — cumulative exposure over time — and tells you when to act.
Please note: Decibel Meter uses your device microphone to provide estimates. It is not a certified sound level meter or dosimeter, and it is not intended for hearing-protection, medical, or regulatory decisions.
