FYI - Acoustics 101 for Architecture & Interiors Series

[Cellcbern]

Interesting articles (link below) from DHDI's Hanson Hsu which provide more insightful and elegant explanations of acoustical concepts that have been debated in some WBF threads, and a clear comparison and contrast between traditional and "quantum" acoustics:

Haven't seen this explanation of how the ZR ( Zero Reflection) panels work before:

"....Air is forced to stop being a medium for the sound energy by forcing air molecules to behave as individual particles and not in groups as a wave. Hence, sound ceases to exist because it has no medium to travel on. Wherever applied, quantization is an acoustical cloak which removes the ability of the material surface beneath it to affect sound....."

My skepticism of all things marketed with a variation of the term “quantum“ persists.

For the above quote, what exactly are the forces applied? How are they applied? Forcing something requires energy, where/what is the energy derived from? How much is needed?

I posted this as an FYI - not making the effort to explain or answer questions, which I did extensively in my WBF thread "Trying the ZR Acoustics Panels". If you are interested, read the articles to see what is explained. Or don't, if you are too put off by the use of the word "quantum".
