Drop Ceiling Noise Reduction

Acoustical drop ceilings can help provide soundproofing in two different ways.

Drop ceiling noise reduction.

Either by absorbing sound waves thus preventing sounds from bouncing around the room or by blocking sound from traveling to an adjacent room. By their very design drop ceilings are. An nrc of 1 0 indicates that the tile can absorb any sound that hits it while an nrc of 0 indicates that the tile will reflect and disperse any sound that hits it. Unlike the cac the noise reduction coefficient nrc rating system scores ceiling tiles between 0 and 1 0.

The procedure is to install a new joist between each pair of existing ceiling joist. Higher performing drop ceilings can reduce noise by 55 while exceptional performers can reduce noise by as much as 70. The noise reduction coefficient that ranges from 0 to 1 0 indicates how much the material sound can absorb. The scale runs from 0.

An nrc of 0 means that the tile replicates all of the sounds and send it back into the room and an nrc of 1 0 means that the ceiling tile absorbs all of the sound effects. The number expressed as a decimal or percentage refers to a material s ability to absorb sounds. Some drop ceilings have both capabilities while some have one or the other. Floating ceiling joists are a decoupling technique effective for reducing impact noise.

Ceiling tiles with a high nrc and cac mean that the movie playing in the basement will sound crisp and clear but won t reach light sleepers on the floor above. The higher the score the more sound the ceiling tile material can absorb.
