GIK Acoustics' Razor panels are 1-inch thick absorption panels that are lightweight so they can be used just about anywhere, including up on ceilings. I have a pair of them mounted on the ceiling just above where my singer stands in my vocal room here at my Tones 4 $ Studios. My pair measure 24 X 48-inches but they are available in: 24 X 24, 12 X 48, and 24 X 36-inches.
I'm relying on them to reduce any high-frequency flutter echoes and slaps bouncing off the ceiling and affecting the quality of the vocal sound being recorded directly below them. Even though I use a RealTraps Portable Vocal Booth, it only controls the sound left and right of the mic, it does not stop reflections from overhead that causes slaps and comb filtering.
The Razor panels’ core are made from Class-A fire-rated, rigid fiberglass ECOSE® technology absorption material and are 100% environmentally friendly recycled materials and use no formaldehyde or urea formaldehyde. The biggest 24 X 48-inch panels weigh eight pounds and are available in 15 colors. The panels mount to walls using impaler clips—sharp pointed metal fasteners that attach to the wall. I'm hanging them from the ceiling so I'm using eyehooks screwed into the corners of the Razor panels and then using cable tie-wraps to attach them to matching hooks in the ceiling.
The NRC (Noise Reduction Coefficient) is 1.05; compared to foam at 0.4 and will not deteriorate over time as foam always does. Razor panels, with all the shapes available, are an excellent, stylish option for environments such as offices, restaurants and schools for controlling ambient noise.
Prices range from $42 to $67.95 MSRP each.
