desk positioning

Hi everyone, I'm setting up my home studio. Following the 38% rule and positioning my desk facing the short wall, I'd end up with the first reflection points between the door and the wall and, from behind, on the French window. This could be a problem for positioning the panels and correct the reflections. In addition to playing music, I'd also like to mix. Therefore, I’d prefer to avoid positioning the desk on the long wall. Can anyone help me with some advice about a good position for my desk? I've attached a drawing of the room, not to scale. Thanks in advance and good music

The good news is, your room is not a simple L to W ratio so that helps. Yes, the reflective French window could be a problem. Curtain on a take down rail? If possible interpose a large absorbent object twixt you and window, a sofa say or an absorbent gobo.

As ever I shall recommend you go to soundonsound.com and find their many "Studio SoS" articles.

I would put the desk on the French Window side - you don’t necessarily have to hang a curtain on it then - how high is the ceiling? - a Diffusion panel above the desk would be good too - something like this one.

I am by no means an acoustics expert! But I would think facing a reflective surface is even worse than having one 3m behind you?
Sound is omnidirectional, wherever that reflective surface is it will....WELL! Reflect!

TBH most of the problems with small* rooms is in the bass frequencies. Some bags of GF or Rockwool in the corners can even things out. You can of course prettify them if you have the DIY skills!

*Small is a long dimension less than say 11m? One wavelength at 30Hz.

You could be right - but how would it reflect? On the return? If you put Vocal Shield setups behind the speaker I think it would help somewhat - No?

OK, Let's suppose the chaps monitors are 8ins* across? That means they are omnidirectional from about 1.5kHz down and goodly chunk of that energy will hit the window and come back, delayed and mess with the response and surely stereo imaging? And of course, 1k5Hz is slap bang in our most sensitive hearing region and where most information lies.

Shoot! Many folks hand wring about reflections from desktops never mind a socking great window! You can even get a plugin to compensate for it.

*I have to go imperial for sounds and speakers...too 'king old! I am the same with firearms? HAVE to think in ft./Secs and ftlbs! "Joules don't cut it for me.

Bass at 15khz? Do you mean Mids at 1.5Khz? Bass is sorta omni directional - if he has ports on the back it would be - hence the vocal shields like devices - I would like to try it out - audio is as devious as most people think.

I didn't qualify "bass" or " mids". A sound source starts to go omni when a dimension becomes comparable to a wavelength. 1.5kHz is 0.733 of a foot.

But yes, sound IS tricky so try everything.
