Heir Audio 4.Ai - Appreciation/Impression/Review Thread - Page 144  

post #2146 of 2528

I really need some advice to see whether or not I have a good seal for my 4A's (I know this is a 4ai appreciation thread but I can't find a 4A appreciation thread lol).. For all you 4ai owners out there, do you notice that the bass is very soft in them? The best way I can describe how I hear it is that the bass is pushed to the back of the stage and is not an important factor in songs (but it is present enough that you can only hear enough of it). I did a 500 hz-50 hz test on my 4A's and I found that the 50hz is so quiet compared to 500 hz...

 

Is this normal for a 4a/4ai?

My ears say the same thing (with the 4.Ai). It's also been shown objectively as well.

     Congrats, you just confirmed millions or years of auditory evolution

 

http://hearinglosshelp.com/weblog/understanding-the-difference-between-sound-pressure-level-spl-and-hearing-level-hl-in-measuring-hearing-loss.php

 

 

     Now as to why the auditory chain consisting from the ear lobe, ear canal, ear drum, occicles, cochlea, the neural path ways to the temporal lobe all seem to be designed with the purpose to boost the mid to high frequency range....   the theory is, the design is based around better speech reception, as the consenants in almost all languages help to distinguish words.  IE   Ship and Chip, they are very similar, and thus, if you don't boost the higher region, speech is more difficult to comprehend. 

 

And on this same line of reasoning, there was a study done on the larynx (vocal chords) and the study results showed that the larynx also has a resonant frequency, the mid range specifically, thus boosting the consenants.

 

This is as if to say, everything from the vocal cords to to all aspects of the auditory mechanisim are desinged with the focus of language.  Awesome stuff really.

 

While studying the psychoacoustics of sound, anatomy and physiology of the audiotory mechanisim, physics of sound, language aquisition, and the pathologies within....

 

Luckily I never forgot to enjoy sound, to me Iife would be so boreing if restricted to a 2cc coupler.

Does the bass improve if you hold them in? If you rub your fingers against eachother while holding them up to your ear, can you hear the fingers rubbing?

Bass does not improve if I push the CIEMs into my ear. If I rub my fingers (with NO music playing but IEM's inserted), then I do NOT hear my fingers. However, if I SNAP my fingers (with no music playing), I will hear it. If I start playing music, I believe I cannot hear my fingers snap.

 

I would also like to add that when I got my impressions done, my audiologist enforced that I do not use a bite block and instead just leave my jaw in an open rest position. What I find is that if I open my mouth any wider than the position I had when I got my impressions done, then the seal and bass will completely dissapear.

 

I would also like to add that if I move my mouth from this open jaw position to fully closed with teeth on top of eachother jaw position, I hear a sort of crackling sound in both my ears. I don't know if that's normal. This crackling sound only happens if I move my jaw.

Try to take the time to decipher the information there. You will find that the issolation provided by a custom static object placed in a dynamic ear canal is dismal.  (Note: one of the people involved in that study was Dr. Mead Killion, AKA founder of Etymotic Research)

 

Due to the fact that u state bass does NOT improve as you apply pressure to the ciems, this indicates there is no leakage, and you have a proper seal.

 

The ear canal is dynamic, it changes in shape with head movement, jaw movement etc.  Even walking can change the shape of your ear canal, results differ from person to person some people can lay down with their CIEMs in, some people can not, some people can jump on a trampolene, some people can not. But due to the fact that we humans are all unique, there really is no acid test, as what may be true for one person is not always true for the other.

 

Crackling noise = occlussion effect

You mean not static.

My bad, was thinking of a different IEM's graph at the time :p

is it me or the cymbals are quite harsh on some tracks although they are sound clear but too clear to my liking too forward , im using the magnus cable

Try different tips. I had a similar experience and tips make a huge difference.

This IEM good for psychedelic electronic and rock and indie rock? Or is there better for this use, respond quick! Thanks.

No idea on psych electro

 

But it worked well with Cake's album Comfort Eagle which is indie.

I'm about set on getting these. I just need to get money in from my returns so should have ordered them by this week. Going to do some reading!
