If you got an iphone or maybe even android device give "etymotic awareness" program (free) a whirl. It'll tell you what you need to know. I just tested it out on my iphone and indeed at 40 volume it is hitting around 100 dB on the 1Plus2! Slightly under it. Raise it up to 45 volume and it's going over 100 dB! (RWA AK100 and Tralucent 1plus2 IEMS). At around 31 it is still around 85 dB sometimes goes over it. But settles around 81 dB average. Still 31 is a bit loud for me but I'd be able to listen to it comfortably for a little while anyways. Listening at around 27 which would be my ideal listening level in terms of louder listening volumes, maxes out depending on track around 85dB but stay generally around 75 to 80 dB. Listening at 21.5 (which is my ideal general listening volume) stays around 70dB average and goes under that.

 

Listening to the Studio V on volume 6 averages around 75dB and spikes at times to 85 db. I generally listen at volume 5 on the Studio V which is slightly less. My point is listening at such levels (that is 85 and above) will damage your hearing in the long run if the damage hasn't been done already.... I found the information out from Planx :). Gotta love Planx :P.

If you have an iPhone, download the free app Awareness! from Etymotic. You can easily measure your dB by placing the IEM on the mic on the iPhone. I can say it's pretty accurate and my volume ranges from 80-85dB. 90 at most when the song gets a bit chaotic in terms of heavy rock or bass.

 

 

 

 

You could be right but that isn't the debate. No one is questioning if 85dB is acceptable or not. Sitting on the sidelines, you're talking about apples and Toad's talking about oranges.

Give it a try yourself and find out. It costs nothing. It's much better to have awareness of what volume you are listening to anyways for safety reasons alone.

Really...?!?

How is jamming an IEM up against a smartphone mic anything but at best an informal, rough estimation of sound energy at the nozzle end...this in no way represents volume at the tympanic membrane...

Ha, ha. That app is pretty funny. I can hum decently loud and it says 90db, then with the iPhone volume maxed out with the gr07 causes interference and at 85% volume says 80db. Looks like I better not hum around people for too long.

Question for you GR07 peeps. I got these this week and, so far, really like them. Sound great and getting better as I get more and more burn-in hours on them. However, the seem pretty inefficient to me and require me to crank my Clip Zip and/or Galaxy S3 near max output levels just to get to a solid but non-ear-shattering listening volume.This is a concern because amps typically are not at their best when pushed to thei limits. Upon investigation, I did discover that the GR07's do indeed have low sensitivity rating of 105db, which would explain why I'm having to crank my source volume so high. For comparison, SM3's are rated at 122db, a whopping 17db difference in sensitivity. So the question is, do any of you experience this same issue? Are you cranking your source to 90% or more to get to good listening levels? I read a lot about these IEMs before buying and never heard this complaint. Am I alone?

Current IEM: SE530
Former IEM's: Triple.Fi 10, Super.Fi 5vi, S4i, HF2
Current Source Gear: iPhone 3G 8GB, Sansa Clip+ 8GB

I've said it before, personally I don't think a Clip+ / Zip powers GR07 sufficiently. Sure sound comes out and they sound OK, but nothing like what a source such as Cowons C2 will achieve, people debated with me that the maths all worked out and a Clip+ can drive them just fine. I still say no, because I've heard the difference, you can obtain much better results with more power and you're limiting their potential without it.

If you want higher volumes, then yeah you'll need to turn your player up a bit.

Something as small as an E6 amp with your galaxy may make a big difference.

I've got the clip zip also and just got the gr07 today. I would have a similar opinion. I do need to crank the volume a good bit to get to a comfortable listening level. And I'm more of a soft to medium level listener. I've got a e07k/ipod classic that I'm gonna try after these have cooked for a while. It will be interesting to see what kind of difference the amp and ipod make. 

 

Also, the only other quality iem that I've owned and can use for comparison is the ie80. The Senn is a good iem but sounded quite bassy compared to the gr07. The vsonic sounds expertly balanced and reproduces a "layered" sound with great instrument and vocals. Honestly, based on my memory I'd say that the vsonic sounds more expensive and more musical than the ie80. Plus the fit was essentially automatic for me...an experience that I've never come close to having with any iem until now. Really enjoying these. biggrin.gif

Lee i'm not sure what you're agenda is here...if you want to listen to your $2000+ setup at a whisper, by all means...but i think it rather ridiculous for you to post that listening at levels anything louder than you do is dangerous and causing damage to users hearing...essentially based on some inaccurate program and referencing a chart that employs vague, ill defined terms 

 

I myself have listened to IEMs and headphones for over 30 years on moderate volumes for a couple of hours at a time (albeit, i'm rarely plugged in for more than 2hrs) with no ill effects ....

 

i'm not implying people don't need to be mindful of their volumes and practice safe listening...

 

FYI: from numerous sources 91db is acceptable for ~2hr/day, 94db for ~1hr/day...

lol I don't listen to my set up at a "whisper" ;). I listen to them around 70 to 85dB generally. I agree with you though on short listening sessions at louder volumes as not being majorly detrimental to ones hearing. But on longer sessions you can count on it. My point is while that program may not be perfect I think it is giving a decent figure of the noise levels in the vicinity. Even with it being quiet and just a fan running, it was showing around 30 dB of noise constant.

 

What I am mainly getting at is being mindful of volume listening to preserve ones hearing. Of course it will really come down to our own choices since it is our ears. But it's good to have the information out there since this is a very big problem across the board & noise pollution being the overall bigger issue at hand. Still it's quite shocking that normal conversation isn't too far away from the limit and it's quite easy to get past that limit without being conscious of it. Even UElover noted how easy it is to listen to the RWA AK100 at dangerous level and indeed he is correct. Anyways I'm trying to find out exactly what the AK100s power rating is which I can't seem to find anywhere. I could do this all mathematically with the figures if that would make you feel better about it. wink_face.gif

I'm not sure what quoting several different people on the gr07 thread was about. Yes they are less efficient, therefore you have turn it up to get similar volume of other more effecient earphones. My point is at arms length it said my hum was louder than nearly topped out gr07 on the iPhone, which clearly isn't the case.

Edit: looks like the Etymotic app is approximately +10db off from the other 2 dedicated noise level measuring apps I have on my iPhone.

Holy Luao!!  I listen to my Studio V at 8, no wonder I can't hear/understand what Lee730 is saying about how he loves FOTMs???!!LOL!.   Funny I see this topic today, I was having lunch yesterday in a noisy restaurant and had a hard time hearing my mom and we discussed hearing damage from earphones!!LOL!!!   So I went home and took the following

tests(below), one of which I that I can't find said I needed to get my hearing checked!   The Siemens and Phonak tests said my ears were fine for my age, and the Univ of S.Wales test was the most interesting, when it went above 6khz I really couldn't hear much, it seemed anything over 12khz  I couldn't hear at all!!!

Maybe I do need testing by my audiologist.   Jaddie posted the following which I like:

 

Here it is: normal speech at conversation distance in a room with average to low background noise ends up at 65 - 70dB SPL. If you set your music level, then take the cans off and listen to a someone talk, you'll have a rough reference. A +10dB change is perceived as a doubling in volume, and a -10dB change, cutting volume in half. If your music sounds twice as loud as conversation, you're running 75 - 80dB SPL, which is still safe for fairly long periods. Peaks in music will go higher, and that's still safe, as long as they are momentary.  You may need to compare speech and your music several times to get a good feel for it. Take your time.

So you listen at volume 8 generally on your second generation Studio V? Seems about right to me. The newer unit is more powerful. I use to listen around 8 to 9 on the older unit. I get the same volume around 5 to 6 now on the 3rd ANV.

I really despise descriptions of noise levels because it's all relative and there is no reference point when you say "city traffic" or "truck traffic."
