Ceiling Clouds & Baffles

Home/Ceiling Clouds & Baffles

Ceiling Clouds are decorative ceiling absorbers bonded to a lightweight metal sub-frame and hung from the existing ceiling. They are designed to provide an effective, economic alternative to installing a full suspended acoustic ceiling.

Ceiling clouds or baffles can be hung vertically or horizontally in ceilings to help with your architectural design goals, in addition to reducing ambient noise in a space. They come in a variety of materials, sizes, colours and shapes. They are used in auditoriums, restaurants, atriums and multipurpose rooms to create a modern appearance combined with noise reduction and reverberation control.

When hung at differing heights they can enhance the interior aesthetics of a room by creating an unusual design feature. They are manufactured from sound absorbing foam covered with a high quality acoustically transparent fabric.

Sound absorption is defined, as the incident sound that strikes a material that is not reflected back. An open window is an excellent absorber since the sounds passing through the open window are not reflected back. Conversely it makes a poor sound barrier. Painted concrete block is a good sound barrier but will reflect about 97% of the incident sound striking it. When a sound wave hits an acoustical material the sound wave causes the fibers or particles of the absorbing material to vibrate. This vibration causes tiny amounts of heat due to the friction and thus sound absorption is accomplished by way of energy to heat conversion. The more fibrous a material is the better the absorption; conversely denser materials are less absorptive.

The sound absorption coefficient indicates how much of the sound is absorbed in the actual material. 1.00 equals absorption of 100% of the incident sound. This absorption coefficient varies with the frequency of sound.

Dimensional changes may occur in HR Ceiling Absorbers dependent on the relative humidity of the area in which they are being installed. Absorbers should therefore be left to acclimatise for 24 hours prior to installation. For best results it is recommended that panels are hung with a minimum 100mm spacing between them.
