DR-SoundMeter

DR-SoundMeter is a compact sound level meter for measuring environmental noise in decibels. The app provides real-time numeric readings with a clear on-screen gauge and straightforward controls suitable for casual and field use.

Overview

With DR-SoundMeter you can view instantaneous, peak and average sound levels. The app offers A-weighting and C-weighting options to approximate human hearing and includes manual calibration to compensate for differences in device microphones.

Features

Real-time decibel (dB) measurements appear as a numeric readout alongside a visual gauge, with tracking for peak and average levels. A-weighting and C-weighting are available, and manual calibration helps improve relative accuracy across devices. An on-screen graph shows short-term trends and you can save measurement snapshots for later review.

How to use

Allow microphone access, place the device near the sound source, and read the live measurement on the display. Use the calibration option with a known reference if greater accuracy is required. For formal assessments or regulatory compliance, consult a qualified expert. DR-SoundMeter is intended for general measurement and comparison rather than certified laboratory testing.
