Decibel Examples

When trying to enclose a piece a machinery, most people will know they want it "quieter," but can't put into acoustical terms the end result (or decibel reduction) they want to achieve. With our audio examples, you can actually hear the decibel differences compared to static pink noise.

Decibel Icon

Pink Noise

An example of a randomized static pink noise. Pink noise uses deeper sounds and lower sound waves.

Decibel Icon

3 dB

Just perceptible. 3dB reduction has a 18% reduction in the perceived volume and yet is just barely perceptible to the human ear.

Decibel Icon

6 dB

Noticeable. 6dB reduction has a 34% reduction in the perceived volume and is very noticeable to the human ear.

Decibel Icon

10 dB

Double/Halving. 10dB reduction has a 50% reduction in the perceived volume and sounds half as loud to the human ear.

Decibel Icon

20 dB

Much more/less. 20dB reduction has a 75% reduction in the perceived volume and most noticeable to the human ear.
