For many years politicians have stated that motorcycle noise is the subject that they receive the most letters about, despite the fact that in the last noise pollution survey did not even mention motorcycles. Unfortunately, this leads to a continuing push for even lower noise limits, although not necessarily lower noise levels.

The current limits for motorcycles are based on the cc of the machine and are as follows:-


ITEM  DATE OF FIRST ISSUE MOPEDS MOTORCYCLES REFERENCE
          
1) Pre 1st April 1983 No Requirement No Requirement  
    
2)  1st April 1983 74dB(A) <80cc = 79dB(A) C&U Schedule to 81 - 125cc = 81dB(A) 7A & directive 31st March 1991 126 - 350cc = 84dB(A) 78/1015/EEC 351 - 500cc = 86dB(A) >500cc = 87dB(A)  
  
3) 3) 1st April 1991 75dB(A) <80 = 78dB(A) C&U Schedule to 81 - 175cc = 80dB(A) 7A and directive present* > 175cc = 83dB(A) 87/56/EEC

Loud pipes announce the presence of a bike, and alert the stupid absent minded pedestrian to look before crossing the road....something a heavily silenced bike/scooter can't do  

Also alert a careless motorist about to turn right across the path of a filtering/overtaking bike, of the presence of the bike.

they also have a slight tendency to make the rider go deaf.

....
I've been riding LOUD bikes for over 35 years, and no ear plugs to cut out the namby pamby "helmet wind noise". I ain't a deaf.
.....

Does the converse hold true that a rider with loud pipes is not aware of approaching traffic because he can't hear it, therefore making them dangerous?

No

Loud pipes save lives!

IMO, Loud pipes are heard by the four wheeled motorists, making them a bit more aware of the MC's presence, therefore less likely to commit lane changes into/onto me or similar undesirable acts.

I also have been riding bikes with straight pipes or megas, for many years and am not deaf yet.
