## What is Impulse Noise Decibel Meter?

Firearm Noise Testing | Sound Level Meter helps you monitor sound levels (dB) in real time. It’s designed for very loud environments such as workshops, concerts, and outdoor ranges, so you can make better hearing-safety decisions.

The app uses your phone’s microphone to estimate sound pressure level and shows current, minimum, average, and maximum readings with clear visual feedback.

Key features
	•	Real-time decibel meter (dB)
	•	Min / Avg / Max tracking
	•	A-weighting (dBA) for everyday noise (closest to human hearing)
	•	C-weighting (dBC) for very loud environments and peak levels
	•	Linear mode for raw/technical readings (no filtering)
	•	Sensitivity calibration (+/−) to compensate for device microphone differences
	•	Clean, readable interface for quick checks

Important notes
	•	This app is not a certified or laboratory-grade sound level meter. Readings vary by device model, microphone hardware, phone case, distance, and environment.
	•	For general information and personal awareness only. Not intended for legal, regulatory, medical, or workplace compliance measurements.
	•	Very loud sounds can damage hearing quickly. Always use appropriate hearing protection in loud environments.

Privacy
	•	Microphone input is used only to calculate sound level.
	•	We do not sell personal data.
