Store description excerpt
NoiseGuard is a sound level meter that keeps a running total of the noise you take in. Most dB meter apps show you the level right now and nothing else. NoiseGuard also adds up today's exposure, so you can see how much of your day's quiet you have already spent. HOW THE DOSE WORKS The daily dose follows the widely used 85 dB for 8 hours reference with a 3 dB exchange rate: every extra 3 dB halves the time you can spend there. 85 dB for 8 hours, 88 dB for 4 hours, 91 dB for 2 hours, and so on. While you are measuring, time spent at or above 85 dB piles up as a percentage of that daily allowance, and the card changes color as you climb: Safe, Caution, and Over the daily guide. FEATURES - Live dB readout with a scrolling bar meter - Session minimum, average and maximum - Today's noise dose as a percentage, with a progress bar and a 50 percent mark - Three bands: Safe, Caution, Over the daily guide, each with a short piece of advice - Time spent above 85 dB, counted to the second - Home Screen widget showing today's dose at a glance - An About sheet that explains the calculation and the limits in plain words - No account and no sign-in needed WHO IT'S FOR - Band and orchestra players, and anyone who rehearses in a loud room - Live venues, clubs and the people who work in them - Building sites, workshops and factory floors - Parents wondering how loud a place really is - Anyone who wants to look after their hearing PRIVACY Audio is analyzed on your device and is never recorded, stored or sent anywhere. Your dose percentage is saved on this device so the widget can show it. PLEASE READ NoiseGuard is not a calibrated measuring instrument. The iPhone microphone has no certified sensitivity, and the reading changes with your case, the direction you point the phone and the wind, so every number is a rough guide. It is not a medical device and not an occupational-safety instrument, and it makes no claim of compliance with any regulation or standard. The counter only runs while the app is open and measuring, so it always under-reports the noise in your whole day. If you are worried about your hearing, please see a specialist. Open NoiseGuard and see how loud your day really is.
