print, they only cut 17 dB, which is 10 or 15 less dB than the reduction
available from decent earplugs! Probably comparable to passive ear
muffs. I'm sure the Bose unit is another matter. But Murphy says it will
fall in the water.

• Loudness increases approximately three times for every 10 decibels. So 30 decibels is three times as loud as 20 decibels. 40 decibels is three times as loud

"Loudness increases approximately three times for every 10 decibels. So 30 decibels is three times as loud as 20 decibels. 40 decibels is three times as loud as 30 decibels. This makes 40 decibels nine times as loud as 20 decibels. "

This is a quote from my hearing aide Users guide booklet. Oops, I guess now the group knows of my quiet world. :>)

A 3 DB change would in fact be about a 33% decrease/increase in loudness.

they didn't answer so far. Also I don't know how much noise (in dbs)
could cut such Quiet Muffler.

I still have acuity hearing loss from my years of working with small
2 and 4 stroke engines - chainsaws being the worst. Stupidly I never
took advantage of a government program to provide custom earplugs
while I was in the trade. But I do have a pair of semi-custom ones
now that I use, if I remember. These aren't that expensive and allow
me to hear normal speech while keeping the higher and lower pitches
out of my hearing range. Easy to insert and very comfortable. I got
mine at a "safety" shop but I think you can get them at a decent drug
store or where power equipment is sold.

I agree that in noisy situations everyone should use good hearing
protection. Good quality, modern disposable earplugs cut something like
30db, which ought to be good enough for almost anything this side of a
jet engine. Crappy, ripoff headphones won't be used after the first few
times, tho the budget crunch might prevent attending one heavy metal
concert and provide some protection. Seems to me 17db from active
