DIY Acoustic Treatment
ultrafoam tile, 50mm
Improve the frequency response and decay time of mid to high frequencies; designed to used on walls and ceilings at reflection points to reduce interference and flutter echoes.
Size: 500 W x 500 H x 50 D (mm)
Acoustic Performance: NRC 0.7
Recommendations on Use:
To have an audible effect in the mid to high range frequencies, you will need to cover a considerable percentage of the surface area of the room with appropriate absorbers. In a typically furnished room with a carpeted floor, expect to cover 30 to 40% of the wall and ceiling area.
Mid to high range frequencies are best treated by placing absorbers at the reflection points on the side walls and ceiling (reflection points may be found if you sit in the listening position and get a friend to move a mirror along the side walls until you can see the speaker).
