Acoustic panels: bigger, or smaller?

[pashabel]

Hey All,

I am having acoustic panels built for a small studio, used mainly for vocal recordings with quite a roomy sound to it. I can only treat two of the opposing walls, as the other two walls have a cupboard and window facing each other.

Now, should I rather have two very large panels built - 1.2m x 1.8m - for the walls facing each other, or should I rather have three smaller panels of 60cm x 1.2m built for each wall?

I have attached a sketch of the room.

Thanks!

Might I suggest that you first determine the regions requiring absorption in order to control the early reflections off the side walls and the ceiling using wither the mirror techniques or the ETC response from a program such as RoomEQWizard.

The coverage required of the panels is a function of actual need, not our opinion. The actual coverage requirements will provide a much better answer to your question than our guesses will!


This will tell you the actual regions that must be treated and from this you can better determine what dimension panels will provide optimal coverage.

Also, you are going to NEED to address room modes.

Edit room comment regarding closet - as I mistakenly thought the diagram in another post was the room... ) The rest stands...

You might want to consider ordering smaller panels (600 x 600mm) and position them as you need them - adding as you go if you find you need more...

Flo is designed to be used as lightweight sound absorbers in the upper frequency range (500 Hz and above). These panels help reduce disturbing sound reflections.

Hey, great website and products!

While we are pushing a vested commercial product line, how about listing prices.

They will impress too.


And as far as the 'proper' size for panels, that is worded too generally. It is a case of 'they need to be large enough to do the job'. As semi-rigid panels are normally supplied in 2'x4' panels, there is no need to cut them down any further and simply increase the labor and framing relative to the coverage.

2' x 4' is a very manageable modular format that can be used individually or paired with additional panels as needed.

And as far as how much is required, that is what the ETC measurements are for!!! They will tell you how large an incident area must be treated. The size of the incident region and the gain of the reflection will vary with distance from the source, so no meaningful generalization can be provided. That is why we make measurements, and why one has their vital statistics measured each time you go to the doctor rather than someone merely looking at a statistical chart and entering the average height and weight of a (fill in the blank=X) year old man or woman.
