Estimated measurements

Sound-level readings are estimates and may vary by hardware, browser, environment, placement, software processing, and calibration. Do not use these readings as legal, occupational, clinical, safety-certification, or compliance measurements. Use an appropriately calibrated professional meter and qualified guidance when a decision depends on verified sound levels.
