A dismantlable anechoic chamber for sound attenuation includes a number of interconnected panels. The panels have a groove around their edges. The spaces produced by the corresponding grooves at contacting edges of adjacent panels are occupied by battens. The panels have a sandwich-type structure, in which a layer of sound-attenuating material is positioned between the two main faces of the panel. There is dimensional interference between the battens and the panels. The chamber has, on its internal face, an additional sound-attenuating layer. This sound-attenuating material is a foam-like material. The batten has an intermediate layer of sound-attenuating foam material.

A dynamic environmentally actuated ceiling baffle and system that incorporates sidewalls with cuts or kerfs, top and bottom portions and sensors to automatically, programmatically and manually properly configure the ceiling baffle for optimal noise reduction based on the environment or the needs of the user, and that can be quickly and easily installed onto ceiling structures using integrated locks, cables or magnets, to produce a dynamic environmentally actuated ceiling baffle system, and to provide an aesthetically pleasing image, along with a reduction in unwanted noise and/or room acoustics, using the programmed or manual actuation to tune the ceiling baffle to respond appropriately to the acoustic need.

Provided are acoustic obstruction prevention equipment for preventing acoustic obstruction by appropriately designing a surface structure of elemental surfaces that surround a space or a surface structure of an acoustic diffuser, and a design method thereof.

A plurality of elemental surfaces that form wall surfaces, a ceiling surface, or a floor surface which surround a space are provided. An angle mutually formed by the elemental surfaces is nα (n is a natural number), and acoustic obstruction is prevented by reflection between the elemental surfaces. φ=(1+sqrt(5))/2, α=360°*1/(1+φ). This technique may be used for a plurality of other elemental surfaces that form an acoustic diffuser disposed in a space. Furthermore, the acoustic diffuser may also be formed by rotating and disposing a plurality of units at the above-described angle multiple times.

To improve soundproofing performance of a soundproofing wall constituted by wall members overlapping with a hollow portion therebetween. A resonance state of an outer wall member of a soundproofing wall which includes an inner wall member on the side of a sound generation source, an outer wall member outwards from the inner wall member with respect to a position of the generation source, and a hollow portion which is provided between the inner wall member and the outer wall member is detected. A pressure of the hollow portion is adjusted so that the resonance state is a minimum based on adjustment of the pressure of the hollow portion.

Disclosed is a system and method for mounting a panel (40) such as an acoustic panel, baffle or fin. The system for mounting the panel (40) can comprise an elongate member (12). A base (14) of the member (12) can be configured to enable it to be mounted with respect to a structure. Opposing sidewalls (13) of the member (12) can extend from the base (14) such that, in profile, the sidewalls define a neck portion (N) that extends to an enlarged head portion (H) of the member (12). The panel (40) can have a recess (42) formed in an edge thereof. The recess (42) can be configured to generally correspond to an external profile of the member (12). An inner recess portion (43) of the panel (40) can be enlarged to receive the member head portion (H), with an outer recess portion (45) being configured to receive the member neck portion (N). The outer recess portion (45) can open out of the panel edge such that, when the member (12) is located in the panel recess (42) it retains the panel (40) to the member (12).
