A sound damping wallboard for installation on an installed wallboard, a sound damping wallboard system, and a method of constructing a sound damping wallboard on a building structure are disclosed. The sound damping wallboard comprises a gypsum layer having a gypsum layer inner surface and a gypsum layer outer surface, a sound damping layer disposed at the gypsum layer inner surface for installation between the gypsum layer and an installed wallboard and having a sound damping layer inner surface, a first encasing layer disposed at the gypsum layer outer surface, and a second encasing layer disposed at the sound damping layer inner surface.

A noise reduction apparatus can include a frame and multiple spaced apart panels positioned adjacent to each other. Each of the panels or only one of the spaced apart panel elements may have holes therein to receive acoustic waves for absorbing the waves between the panels. The panels can be attached to a frame or other connection structure so that the arrangement of panels can be hung over a work space or positioned in a work space (e.g. in a wall, formed as a partition or wall, included as part of shelving, etc.). The panels can also be incorporated into a light fixture that may hang from a ceiling or be attached to some other type of support (e.g. a table, a base, etc.). The panels can be composed of glass, wood, or other type of material.

An acoustic absorber includes a chamber formed from walls with a resistive portion providing the only communication between the chamber volume and ambient air. In some examples chamber walls enable selection or adjustment of chamber volume or resistive area, thereby altering the acoustic absorption spectrum below 250 Hz. In some examples the chamber volume contains fibrous filler material exhibiting no airflow resistance or acoustic absorption. Density and heat capacity of the fibrous filler material results in the chamber volume exhibiting compressibility of air within the chamber, for at least acoustic frequencies up to about 50 Hz, that is larger than adiabatic compressibility of air. That larger compressibility results in an increased acoustic absorption coefficient, for at least acoustic frequencies up to about 50 Hz, 50% to 100% larger than that of an identical chamber entirely characterized by the adiabatic compressibility of air.

An acoustic curved ceiling baffle and system that incorporates sidewalls with cuts or kerfs, top and bottom spines and ribs to properly configure the curves in the acoustic baffle, and that can be quickly and easily installed onto ceilings using integrated locks, cables or magnets, to produce a curved baffle system, and to provide an aesthetically pleasing image, along with a reduction in unwanted noise and/or room acoustics.
