Re: [Sursound] Into Sound - Headphone Localization Hearing Test

No, I was talking about spectral artefacts - and not localization.

To apply Heisenberg’s Unschärferelation to acoustics might be a bit  
audacious, because  the size and energy orders are just too big for. 

I haven't listened to your test; but i often create very slight movements
of static sources, (especially when i do static binaural), as to my ears it
does enhance position.
I think that relative to our ears perception, nothing is ever static. We
are always making miniscule adjustments to our own heads axis.
Probably to reduce cones if confusion..

Re: [Sursound] Into Sound - Headphone Localization Hearing Test

Hello (Jo)Hannes,

"After participating in the study, I was one of the people to comment  
that the imposed source movements basically destroyed the timbre of  
the source content."


Application of basic acoustical/perceptual theories < were elementary  
> to come to the very same conclusion. (Even if not listening at  
all.  ;-)


In the end, it is kind of re-assuring if practice meets theory. (Or  
vice versa...)

Hey Jakob,



 Thanks for sharing. I would say the paper is a decent first try on  
some scientific work. :)




 After participating in the study, I was one of the people to  
comment that the imposed source movements basically destroyed the  
timbre of the source content. So even if it would have been shown to  
be somewhat successful in improving f/b-confusions, it did not seem  
like a practically viable implementation.




 Reading your documentation and finding an oscillation rate of 14 Hz  
explains my observation of impaired timbre to me. General head  
movements I would expect to maybe be in a range of 1-3 Hz (what you  
also chose for the other axis). Why did you decide to use such a  
high value in your design?




 Kind regards,

 /Hannes

 Subject: [Sursound] Into Sound - Headphone Localization Hearing Test

 For all the people interested in binaural audio:

 I'm currently working on a new technique to enhance the localization of

 sounds in binaural music.

 To further examine this, I created a hearing test. It would be great if

 a lot of people could participate to get representative results.

 So have fun listening to some Shakespeare and Drums and feel free to

 share the test!

 It only takes around 5 min.

Ok, I got this.

But you can't have it both ways:

Either these small changes are noticeable, but then you also will get  
some spectral = tonal errors. (You don't get tonal errors in the case  
of normal head movements, according to Dr. Theile and others. Even if  
the spectral perception changes because of  head movement...)


OR the changes are too small to get noticed, or tp do anything  
meaningful in the first place...


That's my take. But of course this is easily said/written after such  
experiments. (my thoughts being then a mixture of interpretation and  
objection. "A posteriori", so unfair...    ;-)

Hi Stefan,

I don't think that the proposed method can replace head tracking or  
tries to simulate it.

The used amplitude is way too small to do that.
You can see it more as giving the brain a hint with these little  
right and left movements where the signal is coming from.

But as we saw, it seems that it's not working :)

 I highly doubt that the creation of “involuntary head movements”  
does anything especially good, not being synchronized with  
your/anybody’s real head movements - or say the (complete)  
perceptual system. (Which “could” integrate visual, acoustical,

 This “what you could expect” interpretation  is in line with your finding:



 “Later evaluation showed no statistical difference between the  
amount of correct localized sound with or without oscillation  
applied.”




 As we know that headtracking “helps” to improve front/back  
hearing, isn’t it that the conventional way is better than the  
“proposed new method”?




 The question had to be asked...



 Still a valuable result, in my view:



 “Don’t move sound sources in artificial ways.”



 



 Best,



 Stefan



 P.S.: The tested method  might introduce (noticeable) tonal artefacts, btw.

Re: [Sursound] Into Sound - Headphone Localization Hearing Test

[Jakob Gille]

I recently finished the evaluation of the listening test I made about 
the effect of an oscillating sound source for the localization of sounds 
in binaural music.
I wrote a little paper about it. You can find it 
here:https://lnkd.in/eZsTJ6it

Thank you a lot for your comments!
I'm happy that I included also the option to add comments directly to 
the test because I got recently a lot of helpful input which I suppose 
was mostly coming from the sursound discussion group :)
Regarding the front/back confusion: unfortunately, this is still a 
huge problem, and I'm not sure if my method can help with that.
I would still encourage you to do the test and have your best and 
first guess if the signal is coming from the front or back. It still 
could be that the front/back confusion is overall really bad but maybe 
slightly better with my method.


I did not include hard left, right and center because my method is not 
really helping with the perception of these directions that are 
already quite good perceived.
Another reason was to have not too many questions for the test, thus 
keeping it short.

You need to have “left” “center” and “right” answers too – I stopped 
scoring because I was getting no meaningful front/back, and so my 
answers would have been invalid if I continued

For all the people interested in binaural audio:
I'm currently working on a new technique to enhance the localization of
sounds in binaural music.
To further examine this, I created a hearing test. It would be great if
a lot of people could participate to get representative results.
So have fun listening to some Shakespeare and Drums and feel free to
share the test!
It only takes around 5 min.
