Sound Meter: Decibel, dB, SPL is a simple and practical noise detector app that measures ambient sound levels in decibels (dB) using your device’s microphone. It’s ideal for checking noise in your environment — from traffic to home noise and even floor-impact sounds in apartments.

📲 Main Features
📏 Measure noise in decibel (dB)
📊 Visualize with real-time SPL (Sound Pressure Level) graphs
📡 Easy-to-read live meter display
🏠 Optimized for interfloor (neighbor) noise detection
📉 Show average, peak (max), and real-time values

🔊 Sample Noise Levels
Level Example
140dB Gunshot

⚠️ Disclaimer
Smartphone microphones are designed for human voice and may not measure dB levels as accurately as professional sound level meters.
For best accuracy, calibrate using a real sound meter or set your baseline to 20–30dB in a quiet environment.
