## What is Noise Meter?

Noise Meter measures the sound around you in real time, with a precision instrument dial that shows the current decibel level at a glance.

Track maximum, minimum and average levels along with a live graph of how the noise changes over time.

■ Features
• Real-time decibel (dB) measurement using your device microphone
• Instrument-style dial with a 0-140 dB color-coded scale
• Max / Min / Average statistics
• Live noise-over-time graph
• Save measurements and review them later
• Noise level guide — compare everyday sounds (library, conversation, traffic, concert)
• 85 dB hearing-safety warning line
• Share your results

■ Great for
• Logging noise from neighbors or daily life
• Checking the sound environment of an office, cafe or study room
• Inspecting workplace noise levels
• Measuring how quiet your sleep or focus space is

Audio captured by the microphone is analyzed in real time only — it is never recorded or saved.

Note: This app is for reference and does not replace medical or professional-grade sound measurement. Readings vary with your device's microphone.
