APPLYING THE DAMPING

The biggest challenge to applying the AcoustiPack¬ô materials to the Antec Sonata is that the right side of the case is not removable. The gap between the motherboard tray and the right side panel is too small for any material to be applied to either, as shown in this photo below, taken from the PSU location looking towards the front of the case.

After careful study of the available spaces and access to various portions of the Sonata case, I decided to use the Deluxe AcoustiPack¬ô. I wanted the flexibility of its wide range of materials.

I consulted Acousti Product's fitting instructions, included with the kit, as well as these resources on their website: well-illustrated instructions and FAQ recommendations. Here is the approach I decided to take:

  • Cover as much of the internal surface area as possible without limiting airflow.
  • Apply additional damping around the intake vent, which is closest to the listener when the PC is placed in the typical under-desk location.
  • Combine the Barrier Mass with the Acoustic Foam for maximum noise reduction on the removable left side panel.

1) Antec Sonata case on operating table (dirty floor rug).

*

2) Measure twice... cut with sharp utility knife and/or scissors.

*

3) Top piece for right side panel.

*

4) Between step 3 and this one, there were actually about 3 dozen steps, but you don't need to see them.

  • The composite material was applied on the top, the bottom, and as much of the right side, front and back panels as possible.
  • The foam in the center patches of the right panel in the middle of the motherboard tray were simply cut to size to fit those openings. The mounting standoffs keep the bottom of the motherboard from touching the foam. See 1) above as a reference.

*

5) Some slightly sloppy cutting for Acoustic Composite material behind the front door. A photo was not taken, but a layer of Acoustic Composite material was similarly applied to the inside of the plastic bezel intake vent.

*

6) The right panel with Mass Barrier sheet on bottom and convoluted Acoustic Foam on top.

  • Note the groove in the foam cut out for the crossbar in the case. The thickness of the foam meant that it was pressed very tightly against the side of the PSU. Later, that patch was simply cut away and removed, as AP cautions about having the material directly against heat producing components.
  • Another note: The small holes whose pattern spells ANTEC were covered up on both side of the case. To keeps things reasonably fair, duct tape was used to also cover up those holes in the undamaged case

*

The installation process took more than two hours. (It would go faster if you were not stopping to take photos or make notes.) One and a half sheets of the Acoustic Composite sheet, one Acoustic Barrier sheet and almost all of the Acoustic Contour sheet were used. The total weight gain was about 8 pounds.

The adhesive is very sticky, but can be pulled off and reapplied at least once to get the alignment right. (I actually did it a couple of times with a few pieces.) None of the materials smells much. Finally, the 3 foam blocks for drive bays were added. They friction-fit into place easily.
