Rules Corner: Possible Rules Changes for 2015 - Noise Test

Most of you have probably noticed the following part in the "Possible Future Rules Changes" part of the rules:

T15.8  Noise Test – To improve the sound quality of single cylinder engines for track workers the sound measuring units may be changed to dBC. This is more consistent with human hearing at the higher volumes called out in the rules. Cheap, commercially available sound meters are generally able to display dBC. The committee is also considering a reduction in the noise level.
