KOVACS v. COOPER 336 U.S. 77 (1949)
After earlier suggesting that a ban on sound trucks would be invalid, the Supreme Court held that "loud and raucous" loudspeakers could be prohibited as a reasonable regulation of time, place, and manner of speech. The opinion by Justice stanley reed noted interests in residential tranquillity, and it is cited as a privacy decision. Justice felix frankfurter, concurring, delivered a major attack on the preferred freedom doctrine.
