#Sound decibels scale plus

To work with this web application, simply load this page and wait for the app to initializes. Please note that reloading the app will reload the AudioContext engine and you will need to wait for the engine to completely loads before seeing the sound level data. If you decrease this value, the current sound level will be closer to the quit area (blue zone), and if you increase, it will move closer to the danger area (red zone). There is also a calibration number on the right side which can be adjusted to calibrate the current sound level.

On the top toolbar, you can see min and max values for sound level, plus normalized and average level values.

The graph is colored from blue to red zones where blue corresponds to the lowest sound level and red is for the highest sound and noise level. The X-axis shows the active time frame for the last 30 seconds. Within the graph, the left side is for sound level and the right side shows the noise level in the dB unit. Once the engine is fully loaded, you can see the realtime noise and sound in a colored graph. Then wait for the app to initialize the underlying engine. Please wait for this web app to completely load, then accept the microphone permission to allow the app to capture real-time audio. The app uses the AudioContext API which is supported in all modern browsers to compute the real-time noise and sound level in the decibel unit (dB). This web application is designed to measure the surrounding sound and noise with HTML5 tools.
