A calibrated scale of sound-pressure-level used to measure the degree of ambient noise inside a library. Named after the infamous Thomas E. Dewey and his thunderously-cacophonous presidential campaign against Harry Truman.
The noise-level that's acceptable for inside a library is no more than 35dB on the Dewey Decibel System .
