nicksneddon I think it gauges how much protection you may need ( there are different grades ) – and I did it for my own curiosity as well
Fair enough.
It’s just that looking at the acs website for instance the description for the 17db ones is:
“The standard for amplified musicians, DJ’s, vocalists, sound engineers, clubbers and gig-goers.”
while for 15db it’s:
“Suitable for unplugged musicians including vocalists, wood and brass musicians, and orchestras.”
My last pair were the acs 17s, and I just assumed they always pushed club-goers to them. Elacin have similar with suggesting the 15db ones for club-goers.
I have at times thought the acs 17s felt a bit overkill though. If I ever get round to buying another pair I might switch to the 15s of either, maybe even enquire about the 10s for occasional use - depending on the frequency reponses of them.
