Noise has long been accepted as a
form of pollution. It actually does not have to be that extreme to have many negative health implications.
As an audio engineer, I disagree completely with OSHA because they are not based in science. OSHA is about minimizing monetary risk, not protecting hearing health. The CDC, EPA, NIOSH, WHO, etc. all have MUCH more conservative acceptable numbers.
Harvard Medicine: Noise pollution is more than a nuisance. It's a health risk
"Noise is a relevant problem to the public and to individuals. Noise pollution in Europe is regarded as a serious environmental problem [
1], in Austria it is even the prior-ranked problem concerning environment conditions [
2]. Noise has important health-related consequences such as ischemic heart disease, cognitive impairment in children, sleep disturbance, tinnitus and annoyance [
3]. The effects of annoyance are particularly high in connection with traffic noise"
I think we can agree that motorcycles in many ways are a better alternative to cars, but noise is a serious externality that will not be fixed until electrification. The e-motorcycle field is unfortunately not very mature compared to electric cars.
