A computer-based method for reproducing a sound quality in a performance space is provided. The method includes accessing a multi-dimensional sound signature, stored in a computer, for an audience location in a first performance space. The method further includes receiving sound data from a sound input device in a second performance space. The method further includes modifying the sound data to match a sound characteristic of the multi-dimensional sound signature. The method further includes transmitting the modified sound data through a sound output device in the second performance space.

An object of the present disclosure is to provide a partition with a function of dividing a space in a room and removing fine dust with low energy without requiring a separate installation space, and more particularly, to a hybrid partition with a function of removing fine dust while dividing a space, the hybrid partition including: a partition frame; outer finishing plates; dust attachment plates; an air introduction part; a dust collecting part; a dust removing part; and an air discharge part.

A headset generates an output audio signal to provide a virtual sound source for an object or virtual object by using a room impulse response generated by a simulation using a model of a room generated from image data. The headset may include processing circuitry that obtains the model of the room determined based on the image data. The image data includes depth image data from a depth camera assembly and color image data from a color camera. The model includes surfaces of the room and acoustic absorptions of the surfaces. The processing circuitry adjusts audio content presented by the headset based on a room impulse response determined based on one or more simulations of sound propagation between a target position of an object and a position of the headset within the room using the surfaces of the room and the acoustic absorptions of the surfaces.

In embodiments of the present invention improved capabilities are described for a computer-based method for modifying a sound source, including accessing, by an acoustic processing facility including at least one processor, a multi-dimensional sound profile of an acoustic environment, wherein the multi-dimensional sound profile comprises a time-based sound reflection sequence for the acoustic environment; and modifying, by the acoustic processing facility, a sound source data based on the multi-dimensional sound profile to generate a modified sound data.

A soundproof structure has at least one soundproof cell including a frame having a hole portion and a film fixed to the frame so as to cover the hole portion. The soundproof cell is disposed in an opening member having an opening in a state in which a film surface of the film is inclined with respect to an opening cross section of the opening member and a region serving as a ventilation hole, through which gas passes, is provided in the opening member.

Modules with variable acoustic properties configured for covering boundaries, such as walls or ceilings of a room, for instance a multi-purpose room, in which it must be possible to change the acoustical properties of the room, such as the reverberation time, according to each specific use, where the module has a front face provided with one or more through-openings through which sound energy can enter an inner region of the module, and where the module in the inner region comprises a sound absorbing device in acoustic communication with the through-openings in the front face such that sound energy can pass from an exterior region or space outside the module to said sound absorbing device, where the through-openings can be closed, such that sound energy cannot enter the sound absorbing device and opened, such that sound energy can enter the sound absorbing device.

Ceiling tiles for drop ceilings and drop ceilings with such tiles are disclosed. The ceiling tiles have a main portion that is sized and adapted to fit within a grid of the drop ceiling, and a baffle that hangs down from the main portion. The ceiling tiles may be arranged such that they can be made, shipped, and sold in a flat configuration and folded into a three-dimensional configuration with the down-hanging baffle for installation. For example, a sheet of tile material may have a plurality of fold lines defined in it that allow the sheet to fold in such a way as to define the main portion and the baffle. In the flat configuration, the sheet of tile material may have the dimensions of a standard drop ceiling tile; in the folded configuration, the ceiling tiles may also have standard ceiling-tile dimensions.
