The fans in computer server racks can be intrusive to concentration for workers and the high-frequency noise can insert an obstacle impairing normal business workflow, which is undesirable, but fortunately can be improved. The servers, in a shelving unit, such as 42u server rack cabinet, desks, computers and other hardware and objects in the room exacerbate the problem because the additional surfaces promote the reflection of sound waves into the atmosphere.
Adding foam material to the server room, in the ceiling, floor and walls, can absorb and decrease the undesirable sound, giving your workforce a welcomed sound reduction. Wood, drywall and other office room surfaces conduct sound efficiently, and the soundproofing materials are essential for absorbing sound waves and reducing the sound. It makes sense to install rack solutions, such as foam in the area located behind a server rack, which is the first area that the sound waves from the servers fans reach. This is a strategic approach to handling server noise reduction.
Foam paneling in the walls and ceiling can also help deflect the noise. You may decide to add these sound buffering materials to the room during the room’s construction, or after the room is in use. Even after a room’s construction is complete, removing the wall surfaces and filling the interior with fiberglass or another insulation is an effective approach for handling soundproofing. In addition to foam panels, other types of sound barrier materials can be used to reduce sound. Vinyl sound barrier, for example, is one option. Acoustical wall fabrics insert a layer between the fan sound waves and the wall or ceiling. A hanging baffle or banner can intercept the sound waves in areas that flat foam or vinyl panels cannot reach.
Another option for reducing the sound is installing an alternate cooling source for the server equipment that is quieter. AC fans, for example, installed near a door to move the warm air away from the electronics reduces the server fans spin rate, decreasing the noise. It is also important to ensure that each wall, ceiling and floor is intact without a leak or opening, otherwise soundproofing is not possible.
