Vicky, I think your claim is perfectly just.
There are limits in Sweden for how loud a motor bike can be and the
Swedish police has the proper equipment to measure and the training
how to use it.
Still, when i Harley owner (! only) wants his bike to be loud, the
police cannot do anything. 1/ The driver claims that the bike is
broken and that he is heading for the nearest garage to fix it, 2/
the driver demands to have the decibel meter calibrated on the spot,
3/ the driver claims that the policeman holds the measuring equipment
in a wrong way... e.t.c.
The laws don't work.
Another way is to measure as we measure neighbors partying: How OFTEN
and for how LONG.
If a person has too long parties, too often, it doesn't need to be
very loud. The landlord will give him a few warnings, after that he
will be forced to move.
My own case is the parachute jumpers. They have a strip about 20
miles from here and I can hear the plane just after take off. They
have two planes.
Every fine day between end of march till end of October, is filled
with sounds from one of these airplanes about 70% of the time between
8 am and 8 pm, weekdays and Sundays. The 30% off is when the pilots
are having lunch and coffee.
It's not very loud! Also, they claim that they have bought low noise
turbojets and run them only to 70%. Which is true. But it doesn't
help. The sound is there, all the time, more or less, unless it is
windy or rainy and nobody want to relax in the garden anyway.
Before the parachute club, this was an area which was about 90%
intermittently quiet, that means, you could hear a distant train for
30 seconds, then quiet for seven minutes, then a distant truck for 10
sec, e.t.c.
So what can be done? Nothing, as far as I see it. "We" don't have the
arguments and the awareness needed.
If there is interest to start a movement focusing on "time and how
often" please get in touch.
If you need a decibel meter, Vicky, I would be happy to lend you
mine, but I doubt that it is "properly calibrated" or something.
Klas.
