The perception of noise is quite complicated. But as a rule of thumb: when some noise changes by -10dB, then you hear it about “half as loud”.

Source: I have a university degree in acoustics.

So for the reduction of -12dB here, it will be perceived as “nearly half as loud”. Very different than the “94%” is suggesting.

It’s also only 2db overall, the one frequency they dropped that much.

We agree that the -12dB is what’s important for human hearing … Now, you may agree that the 94% reduction is what counts regarding engineering // fabrication // design.

  -2db* and 37%*
  
  Why are you perpetuating the wrong information?
