📊 HOW IT WORKS

Sound Meter uses your device's microphone to capture ambient audio and calculates the sound pressure level in decibels (dB). The smooth, animated gauge gives you an instant visual representation of the noise around you.

🔊 NOISE LEVEL REFERENCE

• 0-20 dB: Almost silent (empty room, rustling leaves)
• 20-40 dB: Quiet room (whisper, library)
• 40-60 dB: Normal conversation (office, moderate rain)
• 60-70 dB: Busy street (restaurant, TV at normal volume)
• 70-85 dB: Heavy traffic (vacuum cleaner, busy highway)
• 85-100 dB: Very loud (lawn mower, motorcycle)
• 100+ dB: Dangerously loud (concert, chainsaw — hearing protection recommended)

🛡️ PRIVACY FIRST

Sound Meter processes all audio locally on your device. No audio is recorded, stored, or transmitted. We only access the microphone to calculate decibel levels in real-time.

⚠️ DISCLAIMER

Sound Meter is designed for informational and reference purposes only. It is not a calibrated scientific instrument and should not be used for professional noise measurements, occupational safety compliance, or medical purposes. Results may vary depending on your device's microphone hardware.

Perfect for checking noise levels at home, in the office, at events, or anywhere you're curious about how loud your environment really is. Download Sound Meter now and start measuring!
