Is the noise around you actually dangerous? SoundGuard turns your phone's microphone into a real-time hearing-health monitor — so you know when to turn it down, step back, or grab hearing protection, before the damage is done. LIVE DECIBEL METER See your ambient sound level update in real time on a clear, color-coded gauge — from Safe (green) all the way to Instant Injury Risk (deep purple). No more guessing whether a concert, a job site, or your neighbor's power tools are actually harmful. KNOW YOUR SAFE EXPOSURE TIME Every reading comes with plain-language context: what the level is comparable to, and how long you can safely stay in it based on established occupational hearing-health guidance (OSHA-style exchange rate). At 100 dB, that might be 2 hours. At 120 dB, it's seconds. TRACK YOUR NOISE DOSE SoundGuard doesn't just look at the instant reading — it accumulates your exposure over the session, the same way professional noise dosimeters do. Watch your daily "noise dose" build up, with clear warnings at 50%, 80%, 100%, and beyond. SESSION HISTORY & CHARTS Every session is saved locally, with peak dB, average dB, duration, and a dB-over-time chart so you can review exactly how loud your day really was. YOUR PRIVACY, PROTECTED SoundGuard never records or uploads audio. All analysis happens on your device in real time — only the calculated decibel value is ever stored. No accounts, no cloud, no ads. WHO IT'S FOR • Concertgoers and musicians protecting their hearing • Parents checking if a nursery, toy, or event is too loud for kids • Workers and hobbyists around power tools or machinery • Anyone curious (or concerned) about noise in daily life Please note: phone microphones aren't calibrated sound level meters. Sound dB detector readings are estimates that vary by device and should be used as a general guide, not a precise measurement — consult a professional audiologist for medical concerns. SoundGuard — because your hearing doesn't come back.
