Acoustic Design Guide

Featuring Celest Acoustic Pendant Lights

If you operate a commercial space, one of the most pressing concerns can be reducing noise levels. While architectural acoustic treatments using absorptive wall panels and careful finish selection are well understood, few building operators know that acoustic light fixtures can also help them reach that goal. With Visa Lighting’s new line of acoustic pendant lights made with absorbent felt materials, commercial spaces can allow building occupants to experience a greater level of calmness, wellness, and enjoyment.


Visa Lighting's Acoustic Design Guide contains helpful tips to understand how acoustic light fixtures can help alleviate noise challenges in commercial spaces. This guide includes an overview of how acoustic material absorbs sound, the benefits of acoustic lighting, appropriate applications for acoustic lighting, as well as helpful diagrams and inspirational application images.

Acoustic Features Unique to Celest: 

  • Most acoustic-dampening light fixtures do not have enough surface area to make a real difference unless many fixtures are used. The Visa Lighting Celest pendants are large enough to provide significant acoustic effects without overloading a space.

  • The acoustic panels are applied to the sides of the geometric shapes providing multiple, large flat surface areas of sound dampening material.

  • The acoustic panels used within Celest products provide between 5.4 to 21.7 ft2 sabins depending on the model. Adding more surfaces in a space with higher sabins values will decrease the sound reverberation time, leading to a quieter environment.

Technology and Calculations for Building Acoustics

Sound absorption can be expressed in terms of the percentage of energy absorbed compared with the percentage reflected. Every surface in a room absorbs some percentage of sound and reflects the rest. How much is absorbed depends on the surface material and the frequency of the sound. Most sounds cover a lot of frequencies. A zero rating means a material absorbs 0% of the sound energy that reaches the material and reflects 100% back. A 1.0 rating means a material absorbs 100% of the sound energy that reaches the material and reflects 0% back.

NRC (Noise Reduction Coefficient) is a measure of how much sound a surface absorbs across the range of typical human speech. Sabins (in ft2 or m2) is a measure of the equivalent area of an object were it made of a material that absorbed 100% of the sound that hits it; put simply sabins = real area x NRC and is a key part of any acoustic calculation.
