Store description excerpt
Decibel is a fast, accurate, and beautifully designed sound level meter that turns your phone into a professional-grade noise measurement tool. REAL-TIME SOUND MEASUREMENT Open the app and instantly see the current noise level in decibels. The always-live meter starts measuring as soon as you grant microphone access — no buttons to press. A stunning circular gauge with color-coded levels makes readings easy to understand at a glance. PROTECT YOUR HEARING Know when sound levels become dangerous. Decibel uses NIOSH occupational noise exposure guidelines to calculate how long you can safely stay in your current environment. Get vibration alerts when noise exceeds your custom threshold, so you can protect your hearing before damage occurs. RECORD & EXPORT SESSIONS Tap Record to capture a measurement session. Save readings with min, avg, and max values. Export any session as CSV and share it with colleagues, doctors, or building inspectors. Perfect for workplace safety audits, noise complaints, and hearing health monitoring. LIVE WAVEFORM GRAPH Watch sound levels change in real time with a smooth, animated waveform that displays the last 12 seconds of measurements. Easily spot noise spikes and patterns. PROFESSIONAL FEATURES A-weighting (dBA) and C-weighting (dBC) filters Fast, Slow, and Impulse response times Adjustable calibration offset to match reference meters Decimal or whole-number precision display MIN / AVG / MAX statistics for every session NOISE LEVEL CONTEXT For every reading, see what common sound source matches your current level — from a quiet library to a jet engine. Color-coded safety indicators tell you if your environment is safe (green) or dangerous (red). BEAUTIFUL DARK THEMES Choose from three dark themes designed for easy reading in any environment: Midnight Blue, Pure Dark, or AMOLED Black for maximum battery savings on OLED screens. PRIVACY FIRST Your microphone data never leaves your device. All audio processing happens locally on your phone. No audio is ever recorded, stored, or transmitted. We take your privacy seriously. LIGHTWEIGHT Under 4 MB. No bloat, no unnecessary permissions, no background battery drain. Perfect for musicians, audio engineers, workplace safety officers, teachers, parents, apartment dwellers, construction workers, event planners, and anyone who cares about their hearing health.
