Overview

Features & Capabilities

OpeNoise is a real-time noise level meter designed for users who want to measure ambient sound quickly and effectively. It provides A-weighted sound pressure level measurements including minimum and maximum levels, with advanced features such as third octave and FFT analysis. Users can save measurement data in text files and calibrate the app for more accurate readings. The extension also allows displaying noise measurements on a map and compiling relevant metadata.

Though it's not intended for professional use and accuracy may vary across devices, OpeNoise encourages users to share calibration and measurements with the OpeNoise community for statistical purposes. Developed by Arpa Piemonte, this open source tool is ideal for sound enthusiasts and anyone interested in environmental noise monitoring.

User Reviews

OpeNoise is praised for its ad-free, privacy-focused, and open source nature, offering detailed data with calibration options that enhance measurement accuracy. Users value its versatility, especially displaying dB(A) levels, and straightforward interface. However, many highlight the necessity for professional calibration to ensure accuracy, limiting usability for casual users. Background data recording and saving features have room for improvement. Despite minor challenges, it is considered one of the best free ambient noise measuring apps available.
Pros
  • No ads and no data collection, providing a clean and private user experience.
  • Open source (FOSS), appreciated by users for transparency and trustworthiness.
  • Highly functional with calibration capability to improve measurement accuracy.
  • Versatile with various display options including dB(A) measurements.
  • Easy to use with an intuitive interface and useful graphing features.
Cons
  • Requires professional microphone calibration for accurate readings, which some users find inconvenient or limiting.
  • Inability to continue data recording in the background or when device times out.
  • Some users experienced usability issues such as difficulty saving recorded data or long data rows causing display problems.
  • Inconsistent readings compared to professional sound meters, leading to mistrust in absolute accuracy.
