Drop Ceiling Noise Reduction

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

Drop ceiling noise reduction.

Some drop ceilings have both capabilities while some have one or the other.

The noise reduction coefficient is typically labeled as an nrc figure. Soundproofing a ceiling involves preventing the transmission of sound wave vibrations from the underside of the ceiling to the floor above it and vice versa.

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. 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. Floating ceiling joists are a decoupling technique effective for reducing impact noise.

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 scale runs from 0. The noise reduction coefficient that ranges from 0 to 1 0 indicates how much the material sound can absorb. By their very design drop ceilings are.

Either by absorbing sound waves thus preventing sounds from bouncing around the room or by blocking sound from traveling to an adjacent room. 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. The higher the score the more sound the ceiling tile material can absorb.
