Library Alarm Decibel Meter

Quiet Cooperation Training Mechanism

Put decibel meters in the public library and attach alarm bells that are triggered when the noise goes above a certain level. The bells should be loud enough to make communication impossible and could be sound-designed for this purpose. Instead of piercing bells or sirens the alarms could be noise cancelers with lots of random activity in just the vocal range. This might work better in schools.

       You really think this a good idea?

       You could connect it to the sprinkler system for added confusion.

       And it releases 12 random dogs into the library...

       How are these dogs random? Are they chosen at random from examples of every known breed which the library keep in a storage room or is the library assigned 12 random dogs from a large pool of dogs so that every time you contravene noise ordinances at your local library it's always the same 12 dogs that come and savage you?

       I dunno, [hip], I hadn't really thought it through, I think 12 different breeds picked at random would cause the most chaotic effect. The dogs could be selected using the Dewidecimal system.

       Very good! Most louder people do not notice their own noisyness, but might if it is played back to them.

       No.

       This seems rather draconian, and also a little all-or- nothing.   

       Sound travels less well as air density is reduced. Therefore, all that's needed is a massive air pump and a hermetically sealed library. Internal air pressure could then be adjusted to keep the perceived noise below some pre-set threshold.   

       In the library, no-one can hear you scream.

       A fire alarm that works by preemptively burning down the house?
