Ok. I just experienced a totally ridiculous thing. Maybe I challenge for them - maybe I want to proceed on things unjustified, but usually I "work" with these kind of things.

Ready ?

At this moment I am deaf in one ear. Happens regularly. But, also seems to allow for hearing / perceiving things which can not be heard when all is normal. This is in the stage that both ears don't work equally.

Was this important ? totally not. However, obviously I hate the situation, especially when I just applied some theoretical SQ improving feature. So, this stays theoretical until I can hear it in well fashion myself. So, and obviously, I try all to get my ears on par, actually all day through. Depending on the situation (I have this very regularly) means exist to stimulate the curing, and one of it is blowing my ears. This means, close your nose and have some firm blows. Hope for the "plop". Have been doing this for two weeks now, but nothing yet.

Last night, right before bed time I thought to try it once more. Possibly my wife had something to tell me, and I better hear that. :) ...

In the house we have doors which are a kind of loose in their enclosure. So, when closed you can move them and it goes tacktacktack. Btw, they have a self frequency of 16Hz, and I'd immediately know when 16Hz is playing. All doors together will shake in their enclosures at this frequency and it adds sound which normally is inaudible. Quite interesting with movies. Shakers.

So there I was in the bathroom, which measures something like 4x4 meters with a height of 3 meters on average (no flat roof there). Door was closed (window too).
I blew my ears and noticed a beat equal to my blowing. Say three blows in a row, immediately followed by three "shakes".
So yes, the bathroom door shook.

:wtf: ?

I thought I was crazy, and waited for my wife to be ready somewhere else and called her in. First there was her question "what in heaven's sake where you doing ??". I showed her the phenomenon.
We both tried whether it could be my unavoidable movement onto the (concrete) floor, but nothing. Blowing ears ? completely repeatable.


I really can not understand what really happens here. So, mouth closed, nose closed, and my ears tend not to blow steam, so also not air. Didn't fart either. No way I'd be blowing air from my inside to the outside of me. I mean, that might have explained things a little (but still not).

In my view this can only be about my "volume" changing somewhat, like belly retracting and the like. But this is cm stuff and I still can't get it; If you compare this with the volume of the room, what could I contribute to that in such a fashion that a complete heavy 2x1m door (7cm thick) moves.
With music it happens too, but there we are talking SPL levels of maybe well over 100dB. Not so here, or at least not something I can imagine.

Well, talking about SPL, I thought "what the heck, why not take the SPL meter and test". So I just did;
70dB comes from it. :scratching:
Why not take a smaller room ? So, into the toilet (which is normally toilet-sized) and an easy 80dB is the result (meter at 1m distance from me). With the door open I see movement on the meter for sure, but that ain't nothing much.
Btw, the toilet door by accident does not move in its enclosure, so I couldn't be capturing the noise of the door itself ...

I see a relation with my other secret experiment about pressurising the room, where some "application" makes the SPL during music playback the same in each spot of the room.
What I didn't know before, is whatever slightest it takes to increase the pressure. If I only could see how I could change the room pressure by blowing my ears like this can happen ...

Hi Peter,

very interesting. Dou you think that the barometric pressure could influence the listening experience in that way too? Should we open all doors for best results?

Regards,
Georg

P.S.: Hopefully not to find doors with the same resonance frequency  :grin:

if a pressure change is the culprit you would be able to recreate the increased pressure with some compressed air fed into the room

in combination with an accurate (digital) barometer and the db meter

I definitely prefer to have the sliding glass door open in my listening room open, somehow adds to clarity and bass

Hi Peter,
Since I do know a bit about your experiment. I have experienced that this phenomenon works not only in the "treated" room. Have you removed this stuff from your house?
Claudius

Do you mean the padded cell where Peter does all his XX/NOS1 development?

Who's the more crazy? The 'mad professor', or those who give up an easy audiophile life to follow him?

Mani

Ha ha probably both in equal measure.

Paul

Haha,
didn't know, that this is called padded cell. In Germany we call it rubber cell.
Peter,
when will you disclose the nature of your experiment?
Claudius

Peter, it was a big mistake building your house on the premises of an ancient graveyard. Now your rooms are haunted by the 16 ghosts of the past.   :scare:

Joking apart, it makes me sad that you are troubled by your hearing. I hope you get better, and that you give them necessary rest, not playing too loud too often.
The doctors say after a loud listening experience (a concert or something) your ears needs 48 hours to recover. So, NEVER, loud levels for 2 consecutive days.

Ear surgery is progressing, but I doubt there will be a fix for it in our life time…  :old:


PS: Wounded ears recovers faster with more sleep/rest/vacation.

Things get "incomparable" this way, because you'd also be letting out the sound waves. So, standing waves will change (the length of the waves can extend to outside), and of course, because of this the air pressure will change too.

I never tested what will happen to the sound when the room would be over pressured, but it seems an easy thing to do (I have a compressor).

Peter

:fool: :rofl:

Hey Georg,

I am almost sure it does, and possibly more than we can "dream" of. But, this doesn't seem to be about the pressure itself, but merely about how the pressure is spread in the room. Like "energizing the room" does some things ... (fill up with a sufficient amount of sound pressure).

All should be related to how soundwaves are able to propagate through air and the more that is even in the room, the more sound will be "even" ?

Of course I'm now talking merely about this post and further down in the Quantum Heaven topic (http://www.phasure.com/index.php?topic=1886.msg19368#msg19368), but what I "discovered" with this ear blowing thing can easily be related I think.
