The acoustic shutter assembly (1) includes at least one window pane (2, 3) arranged in a frame (4). At least one ventilation duct (7) is arranged in the frame between an outer ventilation opening (8) and an inner ventilation opening (9), extending between a first layer of sound absorbing material arranged at an inside (5) and a second layer of sound absorbing material arranged at an outside. A number of acoustic reflectors (12) in the form of plate material are arranged between the first and second layers of sound absorbing material so that the ventilation duct is separated into a number of respective ventilation channels (13) formed between the acoustic reflectors. Each ventilation channel changes direction at least once between the outer ventilation opening and the inner ventilation opening, thereby at least substantially blocking any linear path from the outer ventilation opening to the inner ventilation opening.

A sound damping door system having a door frame, a compression seal, a door slab, a bottom seal, and a concealed hinge assembly. The door frame includes male and female components adapted to engage each other in a rough door opening between first and second wall faces; and at least one isolation gasket adapted to be disposed between the male and female components. The compression seal is mounted to the door frame. The door slab includes an outer skin; an arched constrainment sheet inside the outer skin; a damping fill material inside the outer skin; and an acoustic insert inside the outer skin. The bottom seal is mounted to a bottom surface of the door slab such that the bottom seal is permitted to move relative to the door slab.

Systems and methods for providing a drop seal assembly which is concealed within an opening in the bottom of a sliding door panel of a top-hanging sliding door. The drop seal assembly may include bottom guide which defines a downward facing elongated slot or track which receives a sill guide therein. The drop seal assembly also includes a drop down acoustic seal which automatically drops down to contact the floor surface below the door panel when the door panel is moved from an open position into a closed position. The distance that the seal drops down upon closing of the door panel may be selectively adjustable to accommodate variances in the air gap between the door bottom and the floor surface due to particular installation conditions. A concealed magnetic bottom seal activator may be used to provide self-adjusting activation of the door bottom seal assembly using two opposing magnets.

A roller carriage for the reception of a sliding door includes a roller module for the displaceable affixing at a roller running path and a basic body for the attachment to the sliding door. The roller module is configured of a first material and the basic body of a second material. The first material conducts structure-borne sound in a first sound conducting range and dampens the structure-borne sound in a second sound conducting range. The second material dampens structure-borne sound in the first sound conducting range and conducts structure-borne sound in the second sound conducting range.
