About this app
NoisePro is built for people who need a fast, credible noise pre-check before the formal assessment: HSE managers, safety officers, construction leads, maintenance teams, HVAC technicians and facility managers. Turn your iPhone into a field noise inspection assistant: • Measure ambient sound levels in real time • Select OSHA, NIOSH and other international workplace noise standards • See action levels, exposure limits and recommended maximum exposure time • Name inspections by site, machine, room or client • Track peaks, threshold breaches and sustained noisy periods • Add calibration offset when you have a reference meter • Export professional PDF reports and CSV event data For US teams, NoisePro is designed around occupational noise language that safety professionals already use: OSHA 29 CFR 1910.95, NIOSH REL, TWA, action level, PEL, exposure time and hearing conservation. Use it on construction sites, workshops, manufacturing floors, plant rooms, HVAC commissioning visits, offices and maintenance inspections. NoisePro is not a toy sound meter. It is a practical screening tool to help you document what you heard, where it happened, which standard you checked, and whether the situation deserves follow-up with certified equipment. Important disclaimer: NoisePro uses the built-in microphone of your device. Measurements are indicative only and do not replace an IEC 61672 Class 1 or Class 2 certified sound level meter, a calibrated dosimeter, or a qualified occupational noise assessment. For legal compliance decisions, always use certified equipment and competent professional judgement.
