While loud sounds can be pleasing to some of us, we have to remain respectful of those around us. This is for two reasons, there may be times when they make loud noises that you don't like. It's easier to ask your neighbor to respect you, if you respect him.
The second reason that has plagued motorcycling for generations is those that don't like the noises that we feel are acceptable, can and have in desperation made a stand to convince politicians and others to limit our rights to ride. This has resulted in the closure of riding areas and race tracks all over the world.
If we don't police ourselves we will be regulated out of existence.
Another thing is to gain an understanding the nature of sound measurement. Every person on this board is intelligent enough and surely understands the nature of sound being a logarithmic unit of measurement. Which means that a 10 db increase DOUBLES the volume of the sound!
Please take a look at this Decibel Comparison Chart. It contains a chart with the OSHA Daily Permissable Noise Level Exposure. Using the 130db measurement listed as acceptable in Moto GP racing, it doesn't even list a sound pressure level that high, so moving down the scale to the next loudest sound on the chart which is 115db. The recommended amount of exposure at 115db is 15 minutes per DAY !
http://www.gcaudio.com/resources/howtos/loudness.htmlWhat level would be acceptable for an entire days exposure? 90db for 8 hours of exposure or 92db for 6 hours of exposure.
Would it be a smart move to set one of these as the legal limit for motorcycle racing? I believe so.
Or would you rather that tracks close down at a more alarming rate than in the past?
Easy choice in my book!
