Provided is a panel suitable for forming a floor covering. The panel has a substantially planar top side, a substantially planar bottom side, and at least four substantially linear side edges. The linear side edges have at least one pair of opposite side edges. The linear side edges may be provided with a locking means.

A habitation block including habitation levels that are arranged on top of each other, wherein at least one of the habitation levels includes adjacent habitation units including an outer shell formed from a cuboid container that includes a placement surface, a cover, up to two lateral walls and up to two face walls, a cuboid interior space which has an edge length of at least 2 m, a walkable base with step soundproofing, a room ceiling, and room walls, wherein the room walls are dry walls with an intermediary space formed between the cover and the up to four lateral walls and between the room ceiling and the room walls, and a monolithic thermal insulation in the intermediary space, wherein the thermal insulation fills the intermediary space completely and is glued together with the room ceiling and with the room walls.

A sound-absorbing panel comprising a padding layer comprising heat-bonded synthetic fibers is described. The sound-absorbing panel has a first outer face and a second outer face which are spaced from each other so as to form a panel thickness between them. The sound-absorbing panel also comprises a channel within the panel thickness. The padding material between at least one of the outer faces of the panel and the channel has a density greater than the density of the padding material far from the channel so that the panel is more rigid in the region of said channel.

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.

Methods and systems for reducing sound propagation between spaces divided by a retractable wall are disclosed. A retractable wall is configured to divide a space when deployed. An edge of the retractable wall is disposed into a track with a channel when the retractable wall is deployed. A bladder is configured to inflate when the retractable wall is deployed and to press the edge of the retractable wall. In this manner, sound propagation through any gaps is reduced.
