Montreal Studio Acoustics

Post by habsrule30 »

Hey everyone,

Me and my brother are from montreal canada. We are young and have become obsessed with art of recording. We have learned everything we know from free forums like this and would firstly like to say thanks.

I have read over all of the prerequisites to posting and really hope im not breaking any rules:

Our goal: Acoustically treat the environment we've been working in for some time.

I've read tons on general acoustic treatment but i we feel we have a bit of an odd room with corners and all kinds of variables that make things a bit complicated. Thats why we came here for advice.

To start we will be building very general broadband absorbtion panels that we found on the gearslutz site:

Once we have general absorbtion in place we will then criticaly analyze the room and fine tune the remaining problem areas.

Once again im familiar with treatment for a generaly symmetric room but because of all of our corners and etc i really wanted to ask someone with more knowledge about the best approach.

Here are my first ever attempts at sketchup:

As you can see there are a bunch of things that sort of confuse me in terms of general room acoustics. The mixing desk we have is a control 24 and is located in front of that "bench" facing towards the wall. We also have a dual argosy style rack space beneath the window.

The room itself without all of the corner pieces is 13 feet long, 10 feet wide, and 7 feet high.

Here is a link to the sketchup file itself:

I know this question may seem to be vague but this room is simply above my head and i could really use some help in terms of where to begin my general abosrobtion before critical analysis.

Thanks for taking the time to read this. And again if i did leave something out that is vital i apologize and ill answer anything that is needed

welcome! what type of monitors are you using? are you planning on just using stands or soffit mounting them? what options do you have for treatments like slats instead of simply using porous absorbers?

Hey!

We are using adam a7 monitors. They are on custom built sturdy wood stands weighed down by bricks in the base. The stand is in front of that bench at the back of the room leaving a gap of about 2 feet between the speakers and the wall.

I would be very open to other types of acoustics such as slat resonators and diffusers. The only thing though is i would not like to build anything permanent in this room as we have been here a few years and are slowly looking into getting our own building. (Still in parents basement) So the reason we figured we would start with those panels is because we could always just hang them yup somewhere else. If there is another solution like i said id be very open to it.

Another thing i realized i forgot to mention. The large door in the picture does not actually have a door. It is an open doorway to the next room which we use as a lounge. Also the miniture door you see in the bottom of the room is a crawlspace and DOES have a door. The window is simple glas.

Hope this helps.

you might try to get the monitors closer to the front wall, and use super chunk absorbers in the corners, panel absorbers on the front wall between the monitors and at first reflection points plus a ceiling cloud. if you have to block part of the window with an absorber then do so. add absorbers on the back wall and have one on a stand you can put in front of the doorway.
start your seated-at-desk position @ 38% of the room length and adjust (a bit at a time - most likely backwards) to accommodate the speakers and room modes. you might find putting the speaker stands on the shelf necessary to get them close to the front wall.
