1. The rule 3.8.(1) Motorsport rule book that the clubs are required to follow is totally inadequate and in fact would not be policable without hiding behind the Judge of Fact scenario. There are other guidelines i.e. the race organisers hand book but these are not rules that can be applied. It fails in the following areas:
No meter height requirement
No meter angle requirement
No windsock requirement
No maximum wind speed requirement
No clear area requirement
All these are critical to getting accurate readings.
Because the measurement of noise has so many var
iables I believe that the only possible solution is that the sport employ the services of an Acoustic Consultant who could write the rule properly and noise test and set an individual noise level at each circuit measuring point. Then if say the level at the Manfeild measuring point was 95dba and perhaps Levels with its measuring point confines was 98dba then a car running at 95dba at Manfeild would also comply at Levels with no changes. This could only happen with expert advice and at considerable cost. Also Resource Consent requirements would have to be taken into consideration.
