how loud is 90db???

[jinx20001]

i ask this question because i pulled my psp earphones out of the box today and there was a tag on them saying 90db max, i plugged them into my 5.5g ipod and couldnt hear a thing, so i turned the volume all the way up and i was astonished at how quiet these earphones were.

im used to listening mainly to shures se530 and ultimate ears 10 pro's and they are obviously no contest for those high end iem's but can anybody confirm the psp earphones are topping out at 90db and that volume is 90db because i am absolutely amazed at the low volume they produce and infact its scary because the other iem's i use would appear twice as loud at half the volume used.

or is it the fact i used an ipod to test them with?? i have not yet tried my psp because i dont use it for music or anything really

thanks all for any responses, i think it is important for people to realise exactly how loud 90db is, if the psp earphones are indeed topping at 90db i should be deaf by now

I know that standing beside a roaring jet engine gives you a 110 dB....

2db over where hearing damage begins according to audiologist

My gues is they are built with a safety zone already in place so you don't damage you hearing! Guess I could do some research Jinx to give you a real answer:-0

cheers guys, i was just instantly suprised at the lack of volume at full volume on a unrestricted ipod, it kinda worried me that if that volume was 90db i am using other earphones wayyyy toooo loud

90dBs is quite loud. I'd love to know what I listen at.

Whats it called, sort of a group buy I guess. When a sound meter is bought by a group and it gets sent to everyone?

A smoke alarm is 100db if that gives you any reference.

Hmm.. My theme on rockbox might be messed up. The volume is in DB but it goes to +6 I think

I listen on -30 to -20 with my IEM's. Well, I did, until I got my amp and now I have no clue about an actual number representing volume.

i think the rockbox reading refers to line level. i.e. 6db louder then a line output.

90db is pretty loud, your ears would hurt/ring after listening at that volume for a few minutes, and you'd probably get a headache

.
The max i listen at is 70db (tested with SPL meter). Any higher then that is fatiguing. 55db is a 'normal' listening volume in a quiet room imo.

90 dB is loud, but it's not that loud. It's well below the threshold of pain, although long term exposure (i.e., more than a few hours) will cause lasting hearing damage, I doubt being exposed to 90 dB noise levels is going to cause most people headaches or ringing ears. If it happens to you, then I'd hazard a guess that you're more sensitive to noise levels than most.

I've worked in some very noisy areas, and I can tell you that 90 dB really isn't that big of a deal, even without hearing protection - as long as you don't stay there too long!

On my speaker rig I start to feel uncomfortable when the volume at the listening position exceeds 72 dB. At this volume level you need to talk pretty loud to a person standing a few meters away from you, but it's not neccessary to yell/shout.

>89db

90 DB is just like 100 DB... but a little less..

Are you dumb? 100db is 10 times as loud as 90db, think of 90db as a trailer truck coming over at 100km.hr from 10 meters away, thats pretty loud

Very loud. You probably wouldn't be wearing headphones for any extended periods of time if you listened that loud, nor would you hear much after a session.
