Noise detection is simply measuring the volume of ambient sound. The measurement results are expressed in "decibels (dB)," which is not a linear unit: for every 10-decibel increase, the sound energy multiplies by 10. The quietest sound the human ear can hear is about 0 decibels, a whisper is around 20-30 decibels, and normal conversation is about 60 decibels.
Our tool requires no additional hardware. As long as your device has a microphone and browser permissions are granted, it captures sound snippets and uses algorithms to calculate the instantaneous decibel value. It also continuously tracks the highest and average values during the measurement. You will see three numbers on the screen: Current Decibels, Maximum Decibels, and Average Decibels. Together, they help you determine whether your environment is quiet, noisy, or approaching a level that could damage your hearing.
