It
should come as no surprise to learn that we live in a noisy world. From the din
of amplified music coming forth from ancient Hondas to power tools, none of us
escapes the sounds of modern times. But high sound levels are nothing new and
many of us have been around long enough to remember be-finned convertibles
running around with AM radios set to Nuclear Destruct levels.
You and I enter the picture, as we happen to enjoy an activity, hobby to
some obsession to others, where high sound levels are more than a by-product,
theyre an integral part of the experience. Who among us doesnt love
the rumble of the big-bore V-8s, whether it be domestic Chevy or exotic
Maserati, the edgy bite of the old Minis, the authoritative drone of the BMW
inline six, or the banshee wail of almost any Italian engine ever made anytime,
anywhere.
Great stuff, except exposure to high intensity sound levels can lead to
permanent hearing loss and its often malevolent partner, tinnitus (subjective
head noises, usually ringing, buzzing, or cricket-like sounds). The
relationship between high sound levels and hearing loss has been known for
hundreds of years, even being referred to as Boilermakers
Disease although it has nothing to do with staying at your favorite
tavern for that extra drink or two
Loud sounds can also make us unwanted as neighbors. The SCCA knowing the
latter has had an official interest in sound control since 1981, when Charles
Kulmann served as the first sound control manager. Since then SCCA has
established its own standards and proscribed methods of sound measurement.
The result today is an objective, replicable, measure of sound output with a
currently stated, maximum allowable, per vehicle limit of 103 decibels (A). We
of the Glen Region take our sound control seriously. Our goal is not to
restrict fun or even to set our own standards. The former is counter to our
avowed purpose as track junkies and the latter would require more time, money,
and human beings than our region has.
Our goals are to help enforce the SCCA mandated maximum and gather data we
hope will help us learn about the sound levels to which were exposed in
this most glorious pastime of ours.
