Hi All,
I have to be near grinding machines which produces low frequency sounds around 80-90 DB. .When i wear plugs it doesnt seem loud at all, but i was near machines yesterday and today i have spike.
I know some of you might say sound travels through skulls, but bones proves 40db attenuation and most of what we hear is through ear canal and 90 DB is not too loud
I am thinking if i dont think its loud since i am wearing 32 db plugs..why would i get spike?
Any idea?
Thanks
