摘要:
A sound absorptive structure for installation on room wall structure to reduce low frequency wave energy and enhance room acoustics. A fibrous, sound absorptive member is of curved section and terminates in tapered side edges for inserted engagement with wall mounted strips. The structure may be segmented with partitions between the segments. Alternatively T-shaped divider strips may interconnect adjacent segments. A further modification utilizes a flat base for wall attachment with end portions of the base folded perpendicularly to the base to provide closures for the ends of a sound member. Intersections between segments of a sound absorptive structure may be accomplished by corner mounted box structures or may be mitered for endwise abutment with one another. Openings in the room wall structure increase the volume of the present wall mounted structure.

To form an audience chamber in a roofed stadium, at least one truss suspendable from the stadium roof and a canopy removably connectable to the truss. The canopy comprises a plurality of parallel, contiguous elongated panels of flexible material. A close-off curtain is suspendable from the canopy when only a portion of the stadium is to be used as the audience chamber.

Adjustable packing strips (3, 4) are held on the inside of a carrying sheet (6) covered with sound-absorbing material (5), and are slidable by adjustment elements (7, 9), which can be actuated and fastened from the outside, within an adjustment chamber isolated against the sounds of a sound-emitting body (2) to project the packing strips beyond the peripheral edge (6A) of the carrying sheet (6).

A noise-shielding panel comprises a flat section spacedly disposed from the surface of an engine body and formed of a fibrous composite, and a contacting section integral with the flat section and formed of the same fibrous composite as in the flat section. The contacting section is in direct contact with the engine body surface and lower in density of the fibrous composite than the flat section, thereby facilitating production thereof and exhibiting a high noise-shielding effect.
摘要:
An acoustical panel mounting element for isolating the panel through its connection to a supporting structure against vibration and noise transmitted therefrom, with the element providing an outer metallic shell for insertion into a pocket formed in the panel and an inner mounting screw receiving sleeve embedded in an elastomer ring carried within the shell.

An improved light-transmissive building element useful for walls, ceilings, roofs, windows, or the like consists of at least two light-transmitting flat sheets, such as panels, panes, and the like, which, together with a suitable frame, define a hollow space in which sound- and heat-insulating means are arranged. A number of transparent, static flat sheets, such as foils of plastic or elastically tensioned, flexible, thin plastic panels which may be coated with light-transmissive metal layers or the like are inserted in said hollow space at a small distance from each other.
摘要:
A sound-absorbing panel having a front and a rear sheet, the front sheet being corrugated and perforated; a filler of particles of elastic material lies between the sheets.
摘要:
A clip is disclosed for securing sound absorbing panels or the like to supporting structures. The clip has a wall plate, a projection extending outwardly from the wall plate and at least two securing members at the end of the projection opposite the wall plate, with the securing members each extending further in one direction from the projection than their extension from the projection in the opposing direction.A sound absorbing system is disclosed and includes a supporting structure, clips, as defined above, attached to the supporting structure, and sound absorbing panels attached to the clips. The sound absorbing panels comprise a sound absorbing panel with a frame extending around the exterior perimeter of the panel, and the frame has a plurality of openings for accepting the securing members. The securing members are placed into the openings to attach the sound absorbing panels to the supporting structure.
摘要:
A loadbearing construction unit which is compression-resistant and bending-resistant and formed of at least one shell and associated support elements. The support elements comprise at least two plate or rodlike elements which are tensioned with respect to each other to obtain a compressive or tensile stress on the elements.

The disclosure illustrates an enclosure constructed of unique building panels. The panels are joined so as to provide an airtight enclosure for housing of air conditioning equipment, machinery and the like. The individual panels provide sound attenuation. Structural reinforcing is provided in each panel so as to eliminate the need for an enclosure framework on which the panels are to be secured.
