Materials for soundproofing of rooms

Macsound sound-absorbing vibration-proof soundproofing material.

Consists of pieces of acoustic polyurethane foam, rubber, reinforcement fabric.

It is a uniformly porous elastic material with an open small pore, due to which sound energy is absorbed and converted into thermal energy.

Depending on the placement and design, it is used both to absorb airborne, acoustic noise and to significantly reduce impact and structural noise.

Suitable for absorption and isolation of low, medium and high frequencies.

Eliminates the effect of rattling, "box resonance".

Prevents the formation of sound bridges.

Very effective when used in wall partitions.

It is also used for wall cladding in rooms where there is noisy electro-mechanical equipment - elevators, hoods, machine tools.

It is used as insulating gaskets, bumpers, as well as to protect the transported cargo from damage, for example, when transporting glass, antiques.

When used as a sound absorbing material, Macsound is effective in absorbing the entire audible and perceptible sound spectrum.

More efficient than acoustic mineral wool due to its density from 60 to 300 kilograms per cubic meter, it saves space, does not crumble.

Suitable for interior work.

Also used for wall soundproofing, ceiling soundproofing and floor soundproofing.

Absorbs impact noise from neighbors.

Easy to install and cut, unlike cotton wool, it does not emit dangerous dust.

Serves as the main vibration isolator in floating floor systems.

With the help of Macsound, a dry floating floor system is made.

Eliminates the sound of steps and the effect of "cold floor".

When laid under a cement screed, it reduces the level of impact noise to 35 decibels.

It is used in the manufacture of a podium for drum kits.

Good thermal insulation in addition to sound insulation.

Eco-friendly.

Macsound is also used to isolate unwanted vibration and rattle from machine tools, simulators, treadmills, as well as soundproofing car hulls, yachts, ships, engine rooms, etc.

WALL SOUND PROOFING OPTION USING MAXOUND SOUND PROOFING MATERIAL

1. Macsound 20mm or 40mm , which is placed between two sheets of drywall.

   For the measurement, sheets of Macsound Prof soundproofing material 20 mm and 40 mm were alternately used.
