Listener position

[Chris 1970]

I checked yesterday with my laser meter, and:
exactly 0.83 (ears to twitters)!
Thanks again to my dealer tune in, 2 months ago.

The bird feeder is in the garden… so, no influence in the sound I suppose

In my situation, the location of the feeder directly impacts the locations of the "tweeters."

Love to see birds too… should be very nice to see them and listen to music!

We have 6 different bird breeds.
The most surprising are the (wild) rose-ringed parakeet with their magical green color

Some of their grand-grand-grand mothers and fathers escaped from cages at the Paris airports long time ago…

What I can tell you: they have good appetite!!!!

Edit: better picture (with a lady… only the man has a rose-ring)

You can adjust that with Taste Optimization

Oh, No! You are feeding them digits? I've heard the expression about biting the hand that feeds you but I never imagined it applied to hummingbirds!

I have a couple of bird feeders, one for seed and one for suet and the birds seem quite happy that I keep them filled. They are outside my bedroom window so not combined with my music listening. I don't think parakeets would make it in Michigan winters, but quite a few sparrows, blue jays, morning doves and a few woodpeckers and nuthatches show up. The last two mostly for the suet.

We are fortunate, we have hummers all year. Although the numbers are down during the winter.

Would be interesting experiment to create a virtual .83 listening position in space, which in my case would be about 4-5 feet further into the room than my actual listening position.

BIG NEWS: if your favorite post new years celebration listening position is off axis, as in attached picture, you simply need need to tilt your head to look at the speaker on the right, instead of straight ahead or between the speakers to get the best balanced sound. In this way, your right ear is partially blocked by your head from the dominant left side speaker.
You heard it here first lol.

I tried this yesterday. I'm not sure I experienced the full effect. Must be something off with my head geometry.

what's wrong with the Missionary Position?

Your correct, the geometry is quite complex, a certain cranium radius is needed to maintain the laminar flow of air molecules towards the ear cavity. Too sharp a turn on the cheekbone, for example, will see the air seperate from the boundary layer effectively reducing the cavities diameter, and you know what that means.

It also takes years of practice to acquire the correct position. The listener must be lying down, feet towards the speakers (body not parallel) and at a 20-25 degree incline on the horizontal, with the head (cranium) tilted at about a 45 degree angle, and looking towards the right or (non dominant) speaker.

I'm told thats the best geometry, but I'm not sure if there has been a scientific study.

Assuming of course that the ability to tilt one's head post new year's celebrations has not been too badly impaired.

It requires the proper amount of hangover for the full effect.

I happen to be sitting a little closer than usual, in around row 1 @.83? and it just sounds just fantastic.

Makes me wonder if the. 83 rule apply to the bigger 350's, komri's and larger rooms?

Can the width of the speakers (and listening position distance) increase with room speakers size?

 

[akamatsu]

I've posted this elsewhere. Adjusting listening position to the 83% ratio, setting the correct listening position in space optimisation, and finally doing a virtual tunedem in SO has resulted in a nice boost in sound quality.

Thanks to the OP for sharing this tip that has cascaded into more music.

If you ever find yourself in Austin, Texas, USA, look up and you may see some green parakeets. Their numbers have been increasing over the years. I did manage to locate their main nesting area; a cellular phone tower.

i have ignored all that has been said in this thread. Instead, I have pondered the calculation of the new feature included in SO2 that now calculates the rotation angle from "Plan South". I have adjusted the inputted angles of rotation so as to give a computed rotation angle of zero in the box identified as rotation from Plan South.

My listening position is exactly in the centre of the room. The above-mentioned alteration works for me quite well.

I have Akudoriks.

Perhaps, I’m missing something here, but my understanding of the rotation angles is as follows.

It’s all about setting the toe in of the loudspeakers in space optimisation.

The rotation angle from plan south is a way to enter the orientation of the speaker to the room. This can be measured with say a protractor.

The rotation angle from the listener is just an alternative way of entering essentially the same information measured in a different way.

The relationship between to the rotation angle to plan south and the rotation angle to the listener Is matter of simple geometry.

The rotation angle from plan south would only be set at zero if the speakers have no toe in. Therefore, I am not sure why you’d want to adjust the other angle to give an answer of zero. If there is no toe in, you’d simply set the rotation angle from plan south to be zero.

My speakers have very little toe-in. So adjusting the setting as described was feasible.
