Soundproof Mortar Manufacturers Discuss the Sound Insulation Principle of Soundproof Mortar

Soundproof mortar manufacturers state that soundproof mortar is mainly composed of cement, quartz sand, sound insulation fillers, and high-quality water reducers, formulated in specific proportions. It boasts excellent bonding performance, outstanding noise reduction and sound insulation effects, strong adhesion to substrates, low shrinkage rate, and superior construction properties—ready for use immediately after adding water. It features stable quality, convenient construction, low consumption, no cracking, and no hollowing. During application, add an appropriate amount of water as required, mix evenly, and apply smoothly on the ground to form a sound insulation layer with a thickness of approximately 30mm.}

(Note: The following part describes related mortar types for context supplementation) Mortar made of cement, sand, and water in a certain ratio is generally used for masonry, walls, or floors in humid environments or underwater. Mortar mixed with appropriate admixtures such as fly ash and attapulgite in cement or lime mortar is designed to save the usage of cement or lime and improve the bonding performance of the mortar. Common plastering mortars include cement-lime mortar, cement-clay mortar, and lime-clay mortar.

Sound insulation materials have low reflection of incident sound waves, meaning sound can easily enter and pass through such materials. It can be imagined that such materials should be porous, loose, and air-permeable—typical porous sound-absorbing materials. Their structural characteristic is that they contain a large number of interconnected micropores from the surface to the interior, i.e., they possess a certain degree of air permeability.

Sound insulation is generally divided into three types: 1) Attenuation at the sound source; 2) Attenuation during propagation; 3) Attenuation at the human ear. Sound insulation methods refer to measures taken to block sound waves from direct transmission during their propagation in the air by using various energy-absorbing substances to consume the energy of sound waves—such measures are called sound insulation methods.

Any material that can be used to block noise is generally referred to as a sound insulation material. There is a wide variety of sound insulation materials, with common ones including hollow bricks, reinforced concrete walls, wood panels, gypsum boards, stainless steel, sound insulation felt, plywood, etc. Strictly speaking, almost all materials have sound insulation effects; the difference lies in the degree of sound blocking performance among different materials. For the same material, its sound insulation capacity varies significantly due to differences in surface density. Sound insulation capacity follows the mass law principle: the higher the surface density per unit area of the sound insulation material, the better the sound insulation effect—surface density is positively correlated with sound insulation capacity.
