Decibel
Volume Measurement
Decibels quantify sound volume, with higher values indicating louder sounds.
Whispers are around 30 decibels.
Threshold of Pain
Pain threshold begins at around 120 decibels for humans, so anything above can be harmful.
A rock concert can hit 120 decibels, requiring ear protection.
Logarithmic Scale
Decibels are measured on a logarithmic scale, so each 10-decibel increase represents a tenfold increase in intensity.
60 decibels is ten times louder than 50 decibels.
