"Threshold of Pain"

[iceteebone 5,000+ posts]

I learned in American Popular Music Class about sound and shit. He told me the Decibals thats the "threshold" of pain, but I forget what it is. I wanna learn about sound. How not to turn it up to loud to blow my ears out, etc. I just wanna learn the basic shit. Like how to know how loud subs/speakers can go, and how loud you should listen to them etc.

any subwoofer system can cause hearing damage. i believe it's something like over 100 db's can cause hearing damage.

My girlfriends dad has a book about that. it starts at about 125 db's.

i was taught 120db is the threshold.

120dB @ a specific frequency does not equal 120dBA...the weighted "A" scale is generally used for determining OSHA hearing thresholds.

And I believe it's around 85 or 90dBA that begins to get regulated by OSHA as prolonged exposure will result in hearing loss, but that's just IIRC...someone who works in industry probably could get a better number.

It's 85dbA.

It's 85dbA.

Indeed it is, but that is for exposure for 8hrs in a day. In Europe they consider it 80dbA for the same thing.

On the same note for every increase of 3dBA (ISO - Europe) or 5dBA (OSHA - US) you need to reduce the time exposure by half.

The threshold of pain is 130dBA and is at the extreme of what the ear can distinguish in loudness. Of course the A weighting greatly reduces the low frequencies in a logarithmic pattern (as does our ear) and for loud volumes we should talk about C weighting which is a better approximation. Anyway my point here is 130dBA is going to read WAY higher on a non-A weighted RTA.

my mom printed out a bunch of stuff on "damage to the body from loud music" and it said that listening to a 150db system is the equivilant of standing behind a jet as it takes off... don't know if that's true or not. it also said most conversations with others reach 60db or more!! thats more than my type-r's did on the tl. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

150db is indeed really friggin loud and depending on the jet true.

60db is normal conversation. Your type R's should do more than 60db with 1 watt.

x2.

The actual threshold of pain (the average anyways, which varies by person), where you start to immediately feel pain is something like 140dB, though as stated, much lower levels can cause hearling loss from extended exposure.

i was joking about the type-r thing, lol.

Well, according to Bruel & Kjaer it is 130dBA which of course could be 140dB unweighted but it will always be specified as an A weighting. And you are correct that much, much lower levels can cause damage.

wow Im screwed. But hey, life's too short to not enjoy the pleasure of face raping bass.
