Soundproofing Products and Materials
Several building materials that are publicized as having characteristics of noise reduction. Some are very effective in soundproofing, supported by test data as proof, while some others are only slightly effective or make deceptive claims. Diverse frequencies of noise and diverse modes of transmission require diverse materials fitted in diverse places; this kind of scenario will need your knowledge of the background to guide you in the direction of the ideal solutions for the situation in hand and save you from squandering your effort and money on useless approaches. Given below are some of the most frequently used materials proved to be effective for soundproofing walls, ceilings and floors.
Drywall panels
Drywall (known also as plasterboard, wallboard or gypsum board), like Sheetrock. This is an inexpensive and very good material, and is an important item in soundproofing.
Damped drywall
This is drywall that has a layer of sound damping. You can make damped drywalls yourself cheaply by sticking two sheets of normal drywall with damping compound in between.
Sound blocking (deadening) fiberboard (also known as acoustical board or soundboard)
Because they have low mass, they are not ideal for soundproofing walls, though sometimes used on floors in the form of a spacing layer when extra mass is not necessary. They are not suitable for damping, absorption or decoupling.
Mass-loaded vinyl (MLV)
MLV is a very flexible and solid membrane marketed under different brand names. Though expensive, MLV provides a good mass. MLV is ideal for filling openings, and for covering pipes, ducts, and metal pillars, where you need a flexible barrier of sound.
For use as a layer for soundproofing of walls, ceilings and floors there are other options that are relatively more effective as well as cheaper compared to MLV. (Drywall is a less expensive mass while Green Glue is a better damping agent for all frequencies.)
Fiber, when packed loosely serves as a very good absorption, plays a role in soundproofing, though a small one. Normal fiberglass insulation equals a mineral wool in effectiveness and much cheaper. Foams are great thermal insulators but in reality not good for soundproofing.
Sound curtains
Ordinary blankets or curtains are not good enough for soundproofing, but there are curtains for noise control, which are produced by industries incorporating a weighty layer of MLV
Damping compound
Noise proofing compound which is a viscoelastic adhesive, like Green Glue is actually a damping layer used between layers of plywood, drywall or subflooring. This material is highly effective as an inexpensive noise reducer used specially to tackle the low-frequency noise from home theatres, music, construction machinery, etc.
Acoustical Sealant
Also known as acoustical caulk this is essential for sealing joints, for preventing sound leakage. With improper sealing, the effect of the soundproofing materials will be considerably reduced.
Hardware for decoupling
These include drywall furring channel, resilient sound clips or resilient sound isolation clips. Proper installation of such hardware is very critical.
Pre-built units
Doors and windows are examples of pre-built units made to be soundproof and so are portable mini soundproof rooms.
