A sound-attenuating enclosure for a portable machine.

The enclosure includes an inner shell, an outer shell, and a duct.

An acoustic enclosure (also known as a soundproof enclosure, sound enclosure or noise enclosure) encloses noisy equipment in a room or a chamber.

In the laminate, moreover, the storing elastic modulus of each sound absorbing layer becomes gradually lower from the first sound absorbing layer to the outside.

The sound-dampening sheet comprises a sheet-like sound-dampening material.

The windband also provides a structure for attenuating sound.

There is a soundproof lining along the back face of the board.

The composition provides for an open cellular surface capable of absorbing sound.

According to the invention, an economically-produced, noise-absorbing floor structure can thus be achieved, whereby the floor pan (1) is protected in the noise-absorbing region from ingress of dampness and dirt.

The invention relates to a sound-damping partition, especially for the internal equipment of buildings.
