Base Traps (Acoustic Foam)


KHUK

Recommended Posts

Hello fellow VP's

This Monday I will be moving to a new studio area to better facilitate space and recording environment.

I've just ordered a batch of pyramid tile foam, enough to cover wall to wall and like the studio I use now, I never bothered to included any base traps.

I know this is essential to have in any one studio that's the reason why I've ordered four, but my question is this: Do I install them in each corner of the room and will one for each corner be sufficient enough to treat the area?

I'd appreciate any feedback

Thanks

Hello Kris,

While I don't know the shape or dimensions of the room you are subjecting to acoustic treatment, I can tell you that you're on the right track.

Either with rigid fiber glass, mineral wool, or in your case; pyramid foam, corners are the best location for bass (base) traps. Think of a corner as a cubic-parabolic reflector in need of dampening. Essentially, you are removing a corner while at the same time, dampening reflections.

My question is, did you actually order enough pyramid foam to literally cover wall to wall? If so, your corners ought to be lined substantially enough to absorb plenty of reflections (again, I don't know the size/shape of the room).

Corner traps are most often placed in rooms where the walls are not fully treated. They generally compliment an array of multiple, staggered, separate wall tiles or panels. Click here for more basic info.

Hello Carl,

 

Sorry for the late reply. The room is an exact square, all four walls are the same height and length each with a corner of the same height and length.

 

The order arrived today, I have enough pyramid tile foam to cover every area of the room. I have four base traps that I bought for each corner - I still haven't installed them yet as I'm not sure if they are the right size for the area.

 

I did look further into what you replied and according to what I found and also what you mentioned, I would almost certainly need to have it lined substantially to absorb plenty of reflections because of the size of the studio.

 

You've definitely put me on the right path, I now know more about base traps than I ever did before.

My DH is a Physicist, he wanted me to put in his 10 cents here.

 

Once you have installed your pyramid foam, you should do some test recording. A Cello or an Electric Base is a good test. Be careful not to create an artificially flat or too "shocky" base situation.

 

Look at the spectral response, Most of the time, bass traps are only needed in two corners.

 

P.S. I'm just the messenger here . . . I should get him to join himself instead of reading over my shoulder.

Yeah, let him do his own typing! haha!

 

Actually, I'd love to hear more on the science of sound.

I get a headache looking at formulas in audio textbooks.

Id love to know too! Id would be great to have someone to explain it!

Bring him in fi you can! Does he have much spare time? He could write his own section on our site about sound, it would be fascinating! :)

Thanks for the info, im sure to try it out :)

Thanks Tech Mom, It's made it more confusing but still worth it. I'll give it a try and see what I can work out. I'll post some photos once I've finally installed it. You should get your DH to sign up, many people would be grateful for his expertise on sound environment.
