Cellulose insulation soundproofing.

The density of cellulose gives it an advantage over other forms of insulation such as fiberglass. Sound deadening with blown cellulose insulation. It has an stc rating of 44 and an nrc of 0 80 and can be added to walls floors and ceilings during or after construction. What this means is cellulose insulation can absorb 80 or more of the sound it comes into contact with.

The second is the cellulose materials ability to trap air. Cellulose insulation products have an nrc rating that can range upwards of 80 or higher depending on the product and the wall floor or ceiling design where the material is installed. Cellulose insulation works to reduce the lateral movement of sheetrock which decreases the amount of sound that can travel through walls. The significant difference between noise reduction with cellulose and fiberglass is its density.

The first is that cellulose completely fills cavities leaving few air pockets for sound to travel in. Cellulose is approximately three times denser then fiberglass.
