~ Hurt problem ~

No idea what size "small" sleeves like http://www.amazon.com/Comply-T-500-Isolation-Earphone-Platinum/dp and those that come with isolation earphones are, but the foam ones hurt my ear.

Not sure what size "slim" is http://www.amazon.com/Comply-P-Series-Slim-Foam-Tips/dp/B001F0RPHU

made have to get custom-made

best place to start looking?

good links are good!

~ Evil noise problem ~

The highest the Shure brand gives seems to be ~37 db http://en.wikipedia.org/wiki/Decibel#Acoustics

Not sure what's the best db chart/scale but I need one that is likely 80-120 or higher

db are logarithmic

umm.. 80-120+ looks doable on the charts

You want 80-120dB isolation?,  As you know, decibels are not linear, a 10dB increase is roughly twice the volume, generally 30db and below is considered relatively inaudible. Most cheap in ears will isolate around 10-15, which you will immediately notice. The most isolating universals are probably the Etymotic er4p`s as they have long, slim housings and elongated stems, with foam tips they are said to isolate around 42dB, with silicone tips around 36 (thats 8x more than cheap in ears), so about the same as Shures with foam olives, not sure why foam tips hurt your ears, they are often considered comfier than silicone tips, especially comply ones.

"not sure why foam tips hurt your ears"

-- uhh i don't know, small ear canel probaly?

"around 42dB"

-- ....that's not what was asked for.... that's pretty much the same as shure....

"is considered relatively inaudible"

-- uhh..... by who.... it's based on the charts/scale

i think this needs a custom-made approach.

anyone experienced with good advice on that?

Keep in mind your body can also hear and there's no such thing as dead silent isolation (80db). What you're looking for is unachievable and unrealistic.

Instead of posting links, describe better your situation, but again: no headphones/IEM/CIEM/protection hearing/panel mounted will save you from external noise no matter what you do.

don't need 'dead silent' (never wrote that)

the range in db above is fine

anyone know about custom made? or anything?

and nope, your body doesn't 'feel' it.

body doesn't feel it at ~37 db

good links are good.

be sure to post good links.

also, "unachievable and unrealistic" is wrong and a mistake

that's what they said about computers and everything else

also people from the medivial age and past said all kinds of things

you're like them.

everything is possible.

You're right dude.

5 db is a lot in terms of sound, its a 50% increase in volume, the difference between 37 and 42 is considerable, the reason i said the ety`s where better was because they isolate the same amount with silisons as the shures isolate with foams and foam tips hurt your ears, if you have small canals, buy the small comfort comply tips, they have a slightly shallower fit and are much more ergonomic, ask your gp to look in your ears with an otoscope, you may have a blockage or infection if you say it hurts?
