What if a cheap, simple, and safe method existed for preventing permanent hearing loss in tens of millions of Americans?

America’s doctors should be singing its praises and recommending it to their patients. American doctor organizations should be doing the same, as well as vigorously supporting the Hearing Protection Act (H.R. 367 and its companion bill S. 59) or the newly introduced Silencers Helping Us Save Hearing Act, or SHUSH (S. 1505 in the Senate and H.R. 3139 in the House). But they are doing neither. Why not?
