Following complaints to the local Authority's Environmental Health Dept, we have been obliged to start sound testing (ie noise testing) at our Aintree Track Days this year.
Starting with the May 2011 track day , all cars will have to pass a noise test and must not exceed 105dBa at 0.5m from the exhaust at 75% max revs. Any car that fails this test will not be allowed to take part, and no refund will be given. The onus is on the driver to ensure that his or her car complies.
Note that this test is 105dBa conducted at three quarters of max revs, not 108dBa at two thirds of max revs as permitted in sprinting.
