Sound absorbing material controls reverberant sound pressure levels within a cavity, enclosure or room. Soundproofing can reduce the transmission of unwanted direct sound waves from the source to an involuntary listener through the use of distance and intervening objects in the sound path. Soundproofing can suppress unwanted indirect sound waves such as reflections that cause echoes and resonances that cause reverberation. Acoustic quieting and noise control can be used to limit unwanted noise. Two distinct soundproofing problems may need to be considered when designing acoustic treatments-to improve the sound within a room (see reverberation), and reduce sound leakage to/from adjacent rooms or outdoors (see sound transmission class and sound reduction index). Acoustic panels can play a role in treatment only after walls, ceilings, and floors have been soundproofed, reducing reflections that make the overall sound in the source room louder. Absorption in this sense only refers to reducing a resonating frequency in a cavity by installing insulation between walls, ceilings or floors. The absorption aspect in soundproofing should not be confused with sound-absorbing panels used in acoustic treatments. There are five elements in sound reduction: absorption, damping, decoupling, distance, and adding mass. There are several basic approaches to reducing sound: increasing the distance between source and receiver, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles, or using active antinoise sound generators. Soundproofing is any means of reducing the sound pressure with respect to a specified sound source and receptor. As such, our rolls cost $1.99 per square foot for B-Quiet Extreme and $2.98 per square foot for B-Quiet Ultimate vs $4.41 per square foot for Dynamat Xtrem Bulk Pak.A pair of headphones being tested inside an anechoic chamber for soundproofing These sheets are then cut to size, but often need to be combined to fit the size of door or floor that you are covering, resulting in more seams and a less custom fit.ī-Quiet Sound Deadening is affordably priced as we are the manufacturer. The result is less seams to deal with.ĭynamat sound deadening is sold in sheets. Both of these sizes come in rolls and the consumer cuts them to size.

Either 12 square feet, or 50 square feet. B-Quiet automotive sound deadeners are sold by the roll. Dynamat is offers the exact same mix and has a foil outer layer followed by sticky backing.ī-Quiet Sound Deadeners and Dynamat Sound Deadeners are produced in similar methods, however they are sold in different formats. B-Quiet Ultimate is a 100% butyl rubber also with a foil outer alloy and sticky backing that creates a material that works extremely well at stopping noise and vibrations in your automobile.

B-Quit Extreme is made with a Butyl rubber asphalt mix with a foil alloy outer skin and a sticky backing that will adhere to almost anything. We are often asked what is the difference between B-Quiet Sound Deadening products and Dynamat sound deadening products, and in this article we hope to answer what are the differences in the two.īoth B-Quiet and Dynamat feature butyl based products.
