Acoustic panels are designed to absorb sound and distract echoes. The sound-absorbing panels are typically used as wall or ceiling panels and help to provide good acoustics in a room.
Acoustic ceilings, also called sound-absorbing ceilings, are installed to improve the acoustics in a room. They are used in offices, classrooms, kindergartens and commercial buildings in general.
Sound-insulating curtains, also called sound curtains, insulate against sound penetration and are used, among other things, to shield against machine noise, between workplaces and to divide rooms into noisy and non-noise areas.
