## Description

**Sound Meter** is a practical Chrome extension that functions as a Sound Pressure Level meter (SPL meter), decibel meter (dB meter), or noise level meter. Using your device's microphone, it measures ambient noise levels in decibels to help you monitor environmental sound and avoid noise pollution that could damage your hearing.

This extension features real-time updates with a chart graph, displaying minimum, maximum, and average decibel readings during recording sessions. It also provides measuring time, with convenient play, pause, and reset controls. While the measurements may vary compared to professional equipment due to microphone limitations, it offers a useful, accessible tool for everyday noise testing and hearing protection.
