Article: Experts tackle motorsport noise - MAS Environmental

is the "thorny question" faced by noise professionals when asked to assist in motorsport issues, said Dr Mike Fillery of Fillery Acoustics in his paper.
says Fillery. "I can subscribe to that - it is exciting. But he wonders how quiet it can be while still retaining the excitement. The level close to the traffic at the start of a race might be, say, 100dB. "If you drop if to 95dB, will that make a difference? Does it stop your enjoyment? For somebody some distance away, dropping it by 5dB might be the difference between hearing it and not. "As far as I know, no-one has tested how annoying motor racing noise actually is," says Fillery. The static test does not adequately measure the potential for noise emissions when the vehicle is moving, said Fillery in his paper. "Many have tried to correlate the static test with the noise emission from a moving vehicle without success". He too secs it as open to cheating - for example, the test can be invalidated by modern engine management systems that allow the static vehicles to be run at the required rpm but at a much reduced power output resulting in much lower noise emissions. Fillery says that LAmax has been used successfully to control noise levels on quiet use days at Donington Park. The LAmax limit for sensitive locations was set as at 5dB above the ambient LAcq. r trackside drive-by LA s., was derived for any individual vehicle. Continuous monitoring ensures that any transgressors can be immediately removed from the track. "This provides both circuit operator and the community with an instant response to overly loud vehicles, unlike the delayed response resulting from a daily LAeq,T limit," said Fillery.

Institute of Acoustics - Cars Don't Get Noisier as they get Faster

Especially when, for supporters, the noise may be an essential part of the experience, "adding a frisson of elemental thunder to the whole drama", said Dr Mike Fillery, managing director of Fillery Acoustics, Milford.
Mike was one of nine experts discussing such issues at the Institute Of Acoustics Motorsport Noise meeting at Silverstone Circuit on March 18. However, a problem "with static testing is that it is difficult to police properly and is open to cheating by competitors," said Mike. • Consistent testing of vehicles requires regular training and proper equipping of noise officers. Yet, "no matter how correct or how fair the testing, there can be considerable pressure upon race officers to turn a blind eye if a significant number of competitors fail their noise test". • Cars don't get noisier as they get faster: Mike referred to the M Sc project of student Robin Lyons, who investigated the variation in noise levels of cars as they travelled along the straight at different race circuits. In 1996, Mike carried out a survey for the Association of Motor Racing Circuit Owner (AMRCO) on the practice of noise control on their circuits throughout England. This enabled Mike to take many noise readings. • "One interesting finding was that for most events not involving major sponsorship, that means most club and amateur events, the noise level from cars increased with the finishing position. That is, the faster a competitor was, then the quieter was his car. This can be explained by the observation that the faster cars would be the better prepared with higher budgets and so their exhaust systems would be newer and in good order." Mike suggested further investigation was needed on whether it was the level or frequencies of motorsports noise that "really bugs noise complainants". He also pondered the best way to set up "effective means of dialogue between noise complainants and motorsports".

Article: Court sets WHO precedent? - MAS Environmental

Consultant Mike Fillery has had a long interest in motorsport noise: "The case does bring into sharp focus the lack of any credible guidance or research findings on the noise impact of motorised leisure activities.
Fillery continued: "The judge did dismiss Stigwood's approach to a balanced solution which would allow a mix of noisy events and quiet periods in favour of his own idea of fixed limits with no idea of how the limits would be monitored.
