Re. Noisy Buses on Dulwich Grove. Found this forum following a search on noisy buses. It may be of interest to those concerned that bus noise ( specifically concerning the cooling fan ) is a national problem. We live on what was a quiet residential road in Nottinghamshire.We now have upto 7 buses an hour passing within a few feet of our house, most of which are empty. The worst noise levels ( 95+ decibels) are from Optare Tempo vehicles. The EU directive states that the noise level of a normal single decker vehicle should not exceed 85 decibels. However, as stated elsewhere in the forum when the bus is tested the cooling fan is not taken into consideration. So, consequently many people have to suffer a noise comparable to a jet liner on take off. As we have discovered during the last few years, one must not critiscise buses as they are deemed to be "green". If it was a motor cycle or Heavy Goods Vehicle responsible for this noise level those reponsible would be prosecuted and the vehicle impounded. But in our experience bus companies appear to be a law unto themselves. Good Luck to the residents of East Dulwich Grove ( PS We have been suffering for 5 years )
