We understand that to most people, it can be difficult to try and understand what results acoustical treatments can achieve. For example, although it may be understood that a piece of machinery is "loud" and the desire is to make it "quieter," most people cannot put into acoustical terms what result (or decibel reduction) is desired.
Below are several audio examples that demonstrate how different decibel levels are perceived and how they sound to the human ear.
We recommend you start with the pink noise button. This will give you a starting point, allowing you to hear an example of a randomized static pink noise.
From there, you can click on and hear 3dB, 6dB, 10dB and 20dB drops to experience how each example compares to the original static pink noise.
