If the density is too high, the waves get reflected off the material's surface. If the material's density is too low, the sound waves are transmitted through. High enough and sound waves get damped low enough and they get absorbed. For a material to be sound proof it has to fall within a proper density range. It is measure of how packed together, the molecules of a material are. Density is the amount of mass per volume of a substance. Before studying some of these materials, we need to first get an understanding of what properties make these materials unique. There are a few materials that can effectively carry out soundproofing. One might imagine that soundproofing can be achieved by any material, this is however, far from the case. ![]() ![]() Damping: A form of absorption in which the oscillating sound waves are made to undergo resonance, with respect to the surface it hits.The sound energy is converted to kinetic energy through vibrations, and finally to a miniscule amount of heat, through inter molecular friction. When sound waves hit any surface, some get transmitted through the material, some get absorbed within the material and a percentage gets reflected (depending on the absorbing quality of the surface). In absorption, soundproofing is achieved by the reduction of the energy of the sound waves. Absorption: Absorption and/or damping are complex forms of soundproofing, through the use of materials.As a result, the longer the distance the waves have to travel to reach the receptor, the more of its energy is lost. Distance: When traveling through a medium e.g air, the sound energy of the waves is gradually lost converted to vibrational (kinetic) energy in the atoms of the medium.The act of eliminating, reducing or blocking sound is referred to as sound proofing, which can be done in the following three basic ways: Although they cannot be completely blocked, they can be greatly reduced. Since they are waves, sound energy can refract, reflect and maneuver around edges. The noise of a motor engine, external noise in a music studio, noise from a shared apartment etc.There is therefore need for a means or technique to reduce or block it. It's this energy that enables the sound waves to be propagated.ĭespite its vast applications and usefulness, this form of energy is sometimes unwanted and becomes a nuisance or hinderance. These vibrations are converted from kinetic energy to sound energy. Sound waves are as a result of vibrations between atoms or molecules. ![]() As energy, it can be used to break down solids and degas liquids. Aside from being a major form of communication, it's also put to task in geophysics in aspects of signalling, location and positioning. The product was designed to be as flexible, lightweight and easy to install as possible while maintaining excellent damping and professional soundproofing results.Sound is undeniably a very important aspect of our existence. PREMIUM: Dodo Dead Mat PRO was developed in collaboration with leading British motorhome conversion companies in order to meet the specific demands of a professional van installation. Simply cut, peel & stick, safe in the knowledge that the product will stay stuck even with the extremes of van and motorhome life. STICKY: Dead Mat PRO uses our latest high temperature adhesive. This is one of the purest elastomeric sound deadening mats on the UK market. Purer butyl and less mineral filler means better vibration damping and van noise reduction. ![]() To maintain flexibility for those tougher install van areas such as wheel arches, we use our famous HEX embossing pattern.ĮFFICIENT: Dodo Dead Mat PRO has a butyl rubber construction that has less additives than used by many sound deadening competitors on the market. Make those van panels as dead as a Dodo!įLEXIBLE: Dead Mat PRO has a high grade foil for better sound deadening & vibration control. Simply cut, peel & stick Dead Mat PRO on the interior sheet metal of your van conversion to reduce unwanted vibrations & structural noise. All deadening mats are not created equally.ĭead Mat PRO is a superior self adhesive, foil backed sound deadening vibration damper. Designed to give you the performance, flexibility and quality you need for your next van project. Dodo Dead Mat PRO is a premium 2mm sound deadening product developed in the UK in collaboration with many leading van conversion companies.
