Treatment Sluts Advice Needed

[Jonsey]

Treatment sluts,

I have treated the room and plan on adding a couple more bass traps but can anyone tell me what are the possible causes of the dip around the 63 mark?? Also, the top end is spiky?? how can this be improved and the possible causes.

Is this room response looking good so far?? I have always used my ears but this side of things is very new to me as I have been forced recently to relocate.

Many thanks to anyone who can assist me and if any additional info is required please let me know.

Hey Jonsey,

I got your pm. Could you post some pictures, dimensions and and how it is treated?

[Jonsey]

Thanks for getting back to me.

The room is 14ft x 11ft whith a slightly pitched ceiling from 7ft 8" up to 8ft 4".

I have used Ghost Acoustic Treatment which I have had for many years in my previous studio and also have Universal acoustic tiles, some of which I have stuck on the walls and the rest are just resting on the Ghost units (as I try and improve the reading). The walls and ceiling are acoustic plaster board on resiliant bars (behind are batons with rockwall in between). The floor is floating on Neopreme rubber and also insulated.

On the ceiling I have only 1 ghost panel above the seating position and any suggestions improving room would be greatly appreciated!

Im now at the stage where i need someone of knowledge to assist me to the final stage (if there is one).

Apologies, pics are from I Phone.

Many Thanks.

I don't know anything about Ghost Acoustics and the foam you are using, but I would guess it is only helping on the high end which is leaving the low end frequencies untouched. Bass trapping in corners and thick absorption on the back wall should help with that.
See the following as a layout.

The Ghost square panels on the walls are quote:
"effective (30-44%) removal of all audible frequencies down to 200Hz, and around 20% even down to 125 Hz with standard wall mounting."

The bass traps which I have in the 4 corners are quote:
"It offers the same full range frequency response characteristics as the slimmer Ghost traps above 250 Hz, but continues to be highly effective down to very low frequencies, removing around 30% of sound energy even down to 100Hz"

Thanks for the general advice you have offered me but I was looking for something a little bit more specific to my original post.

I don't particularly wish to get rid of what I have and was asking how I can improve it?

Thanks,

I don't think you need to remove anything but add proper bass trapping in corners and thicker panels on the back wall. For the corners you could look filling the corner with fiberglass or straddling 4" panels across the corners.

Cheers I will have a bash and see what happens.
