I had to put 5 panels in my new living room just to live comfortably there, not even talking about the music. There was so much echo coming from the brick walls and concrete ceiling, like in the cave.
Or you could investigate Limp Mass Membranes if you are trying to address a specific low frequency. They work best up against the wall so take up less room. Resonant absorbers, like Helmholtz and Limp Mass, are best for targeting problem frequencies. Porous absorbers are for broadband coverage.What do you guys think about Helmholtz resonators? Could it be more effective and more eco-friendly compared to the bass traps? You probably need much less absorber there, right?
Sorry, cotton couch and Hempcrete panels
I would be happy to build an entire house out of hemp blocks, but you'll probably need a steam isolation on the inside and will close the cells of that hempcrete walls anyway
Known as forever chemicals because they take a long time to break down, PFAS substances were used for decades in carpeting, clothing, food packaging, firefighting foam, cosmetics and other consumer and industrial products. Hundreds of firefighters and others have also alleged in lawsuits that their exposure to PFAS caused cancers, and other health problems are part of some 3,000 PFAS cases consolidated in federal court in South Carolina.Nearly everyone in the U.S. is believed to have some level of PFAS in their blood, according to the Centers for Disease Control and Prevention
Scientists have found links between PFAS and a handful of health problems, including:PFAS might pass to food from packaging, or produce and dairy could have PFAS from PFAS-tainted sludge used as a fertilizer.
Evidence so far suggests that ingested PFAS is absorbed from the intestine, and can travel to the liver, pass into bile and get stored in the gallbladder,...
When bile enters the small intestine during digestion, the PFAS gets re- absorbed into the bloodstream... [said an environmental toxicologist at East Carolina University]
The U.S. lacks comprehensive national testing of PFAS in blood, which makes it difficult to know who is most exposed... [per environmental epidemiologist at North Carolina U]
Thanks! Could you please share the link? I can't find itI think it is Amazon that has designed their own sound absorbing material for use in their office complexes (cube-farms).
I had attempted to get some details on the material referenced as "the Cube" but I only got as far as '20dB absorption'... from un-trusted sources.
Microsoft decided that my legit 'Office' product was worthy of 'de-activation', so the little data that I had on the material was on my Office/OneNote and currently resides in software purgatory... until resolved to my favor.
Few screen captures (thank you SnagIt) for "the Cube":

Material is not obnoxious looking (nor probably noxious-sniffing).
imho: If designed by Amazon; *the price should be quite reasonable, *ethically/organically grown and *will improve your complexion...
