Tiny Closet Space Recording Booth

Now we have demolished a wall in the studio and will expand the large recording room a bit and build a vocal booth I hope you will find interesting!

It is in my nature to be driven forward by challenges. This thread:
Voice recording in PVC blanket booth, how to improve?
annoyed me when it was current, but also inspired me to try to get smallest room possible to sound good. Make the ”impossible” a reality, so to speak.

I actually have a wardrobe at home, of similar dimensions as the one in the thread mentioned above. We renovated the wardrobe recently, but my wife did not want her wardrobe acoustically treated and measured ;-)*

So when dresses and suits hung, neatly surrounded by modest wallpaper and skirting in linseed oiled teak, I used my spare energy to build up the ”same room" with similar dimensions in a big storage space I rent, for testing.



The booth is very tight space to be inside, during longer recording sessions, but one of the comments I got from the musicians was that "it feels like standing outdoors, talking in here”.

Width 130cm
Length 180cm
Height 240cm

But much smaller, after the acoustic treatment...



I think the result was really good. So now that we're going to change the room layout in our studio, we're going to build a similar vocal booth.

Feasibility studies make all the difference! :-)

The test booth has diffusers in the ceiling and on all four walls. HH resonators, adjustable and tuned (approx 70 Hz) in the ceiling corners. The diffusors are V-shaped so they create HH resonators between them.
No windows and no ventilation. I drilled a small hole in the wall to get electricity into the booth for a floor lamp and for the microphone cables. It has no door, but is closed by mounting the last wall with an electric screwdriver.

The booth I am building as a permanent installation in the coming summer, will have both ventilation and windows, a proper door. And of course, electrical outlets and lighting. It will be another challenge.

I want that, even if the space is small, it should acoustically cope with being in the booth for a whole day.

It feels fun to start sharing it all here.
Looking forward for feedback!
Also fun with issues and opinions that challenge and get the project developed. Here we go!

Follow the studio renovation here during the peculiar summer of 2020.

Excellent results! It definitely doesn’t sound like a cramped booth. Very nice.

Sounds great! I'm usually not into vocal-booths but this is something different.
Almost like magic when you consider how small this booth is.

Thank you lads! Nice to hear your positive feedback!

That’s insane. If you could somehow manufacture and ship that as a flat pack (and maybe modify it to be tall enough to stand in) you would get a lot of orders!

HA HA! Bam! Right on target. The package actually is flat.
I have the standard height. 120cm. But it´s possible to get them up to 240cm.
In my studio I have two stacked on each other. (Fits my room´s 270cm height, below the 30cm lowered inner ceiling).

So doesn’t this go against all the advice I’ve pretty much ever read...?

So just to clarify it is possible to create a small ‘vocal booth’ that sounds ‘good’ or rather, like a far bigger space?

Could you elaborate a bit more on the materials that you have used for the V shape diffusers? Have you use any calculated mathematical sequences?

I am a bit puzzled with your results and very intrigued.

Congratulations for your musicianship and keep up to the good work.

it is largely due to that all other broadband diffusors on the market suffer from the same Achilles heel : The  distance to mix position and mikes must be  atleast 3-4  times   the   diffusor lowest working frequency wavelength to avoid ghost speakeras and combfilter effects
World-leading Jamie  Angus and David Howard's book  "Acoustics and Psychoacoustics"  describe    spot on  Berndalens   time delay diffusors  when used in   critical listening rooms  http://diffusor.com/PDF/angus-howard.pdf
A perfect GS example is Dr Hans  small mix room
http://diffusor.com/PDF/Johnny-k-rum.pdf

The  modules  psychoacoustic  replaces the isd gap termination theory, which means that the ISD gap is filled with broadband-dense early reflections that increase resolution and have the big advantage of tracking and mixing in a neutral room
Sweden's studio designer living legend Ingemar Olsson ,who recently got the  very prestigious AES Fellowship Award *,  have used the nearfield diffusors  in over 200 projects  Nigel Jopson (Resolution Chief Editor) visit two of them in Stockholm  and was so impressed he offered SMT to publish the full story
