NOISE MAPPING OF MOTOR RACING NOISE FROM ALTERNATIVE TRACK LAYOUTS AT DONINGTON PARK

In the autumn of 2000, Donington Park Motor Racing Circuit was preparing plans to upgrade the circuit to comply with modem international standards. The planned upgrade would involve substantial alterations to the track layout and to the ancillary buildings around the track. This paper describes the methods used to prepare maps of the noise impact of track use upon surrounding communities. Noise maps were prepared for the existing track layout and for the proposed new track layout for different types of vehicle races. A differential map comparing the two track layouts revealed that the noise impact on most noise sensitive location would remain unchanged as a result of the new track layout. The noise prediction programme was also used to model the pass-by noise levels at distant locations and to model possible changes in pit lane noise arising from relocation of the pit and paddock.
