Computation Method (Formula)<br />
Noise levels generated by rail transport + corresponding unit cost<br />
Noise generate by a link in Watt/ Exposure to over a specific noise level in dB<br />
COMMUTE<br />
· sound intensity = sound power per metre/(p x d)<br />
· sound pressure = square root (sound intensity x 415)<br />
· sound pressure level = 20 x log(sound pressure/0.00002)<br />
· link sound power= number of vehicles*corrected source sound power<br />
· corrected sound power= reference sound power per vehicle per hour*tread break correction factor* disc brake correction factor<br />
+ Corresponding unit cost from UNITE?<br />
