Background Noise

For Topic of the Month

This project detects the background noise, using your microphone. Please be quiet when measuring. If the background noise is over -24 dB, it is considered loud. If the background noise is too high, you will experience poor recording quality. It's recommended to not exceed -48 dB in the background noise for good recording quality.

dB stands for decibels. 0 decibel is the highest possible amplitude without clipping (clipping occurs when the amplitude exceeds the highest possible signal strength in audio samples). -6 decibel is half of the full amplitude. -12 decibel is one quarter of the full amplitude.
