NEW Quiet record  54 dB!

Today the Lamprey River school in Raymond set a new quiet record of 54 decibels.

The custodian shut down the heating and ventilation system and a big fan which gained back about 10 dB of noise.  On their second attempt they tied the McAuliffe School in Concord at 55.  Then on their final attempt I shut of all my equipment  (pa system, speakers, and the projector)  and they hit a new low of 54!

Congrats!  LRES
