This is a most excellent place for technology news and articles.
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?
The snippet quoted in the original comments and referenced in subsequent comments refers specifically to the decibel reduction of the frequencies being targeted by the invention, not the volume of the overall sound.
Is it? Because the next sentence in the paragraph (and the only sentence missing in the quote) is the overall sound reduction. Which is far more important and far less misleading than saying 12db and 94% quieter.
Its intentionally misleading to deceive people, and than the general public incorrectly defends it, this is you.
