Exhaust sound testing

A few years ago they added the abilty to do stationary tests, I don't know if they ever do them.

Why can't you guys just get the noise under the limit? One of the reasons we have a speed limit, is because too many of these boats are too loud.

270:37-a Stationary Sound Level Testing Authorized. –
I. The director or the director's agent may use stationary sound level testing to determine marine engine noise levels for boats. Such testing shall be conducted while boats are stationary on the water according to test SAE J2005.
II. Noise levels in decibels for stationary sound level testing shall be established for a specific distance between the boat tested and the testing device, at levels which correlate with noise levels in decibels, as set forth in RSA 270:37.
III. Testing procedures for stationary sound level testing shall be measured according to procedures established pursuant to rules adopted under RSA 270:39.
IV. Any test conducted pursuant to this section shall be sufficient to establish a violation of RSA 270:37.
