What exactly is a Decibel Scale?
The human ear is capable of adjusting to a wide range of sound intensities. Therefore, rather than a linear scale, a logarithmic scale is used to represent sound levels using more flexible numbers. This scale is known as the decibel scale or dB scale.
- The decibel scale’s smallest audible sound is 0 dB.
- A sound that is 10 times louder is 10 decibels, and a sound that is 100 times louder than near silence is 20 decibels.
- A sound that is 1,000 times louder than near silence is 30 decibels (dB).
