A door-and-window system having a handle component (121), a transmission component (123) and a force receiving portion (12231). When the handle component (121) is operated, the force receiving portion (12231) moves along a first guide groove (12211) via the transmission component (123), and at the same time a driving portion (12232) moves along a second guide groove (12221). Due to a relationship between a guide member (1224) and a third guide groove (12212), a first base seat (1221) translates relative to a second base seat (1222) along a direction of the third guide groove (12212), such that a movable door-and-window (11) can abut tightly against or move away from a sealing member (24) on a door-and-window mounting profile (2).

An acoustical seal system that utilizes a sound absorbing material-based sound seal for the gap or flanking path between a closed door and the nearby surfaces (e.g., the door jam or frame and the floor). When the door is in a closed position, the acoustical seal system may leave a small gap around the door so that the door does not have to make contact with the surrounding structural components. The small gap is an air passage between the two adjacent rooms. The acoustical seal system includes a housing with one or more cavities. The housing is mounted on the sides of the door core or body or on the surrounding components such that the cavities face the small air gap when the door is in the closed position. The cavities are filled with sound-absorbing material, such as an acoustical foam, that is exposed to the air gap.

A noise management system for a window includes an active noise control (ANC) module and a passive sound absorbing module. The ANC module is disposed in or adjacent a ventilation channel of the window and configured to substantially cancel low-frequency noise entering the ventilation channel. The passive sound absorbing module is disposed in or adjacent to the ventilation channel and configured to absorb both high-frequency noise entering the channel and harmonic sounds generated by the ANC module.
