Acoustic Screen Noise Absorbency

 

What is noise absorbency?

 

Noise absorbency refers to how effective a material takes in sound energy, rather than reflecting it back into the work environment. 

 

When sound waves reach surface, they can be reflected or absorbed. Materials such as acoustic foam have high absorbency, helping with background noise, reducing echoes and overall decreasing the level of distracting noise.

 

How will acoustic office partitions reduce noise?

 

Throughout Rap Office Screens collection of partitions we’ve applied a 12mm and 24mm acoustic foam to assist with workplace noise. Offering 2 foam thicknesses allows the user to address low to high volume concerns whilst working within various budgets and panel styles. 

 

Acoustic office screens are an effective method transforming an open plan space into a modern partitioned office. Place in open areas, around desks and in the areas that produce the most noise – placement is the key to effectiveness. 

 

Freestanding and desktop screens are available allowing you to focus on larger areas or on single workspaces such as desks and workstations. Desktop partitions shelter a desk area with light to full cover, variable on the chosen divider height. 

 

 

We’ve tried and tested our foam to see how they perform in a range of frequencies, all of which are shown in the graph above.  

 

The graph shows Absorption Coefficient on the Y axis and frequency across the X axis. The absorption coefficiency determines how far into the material a wavelength can go before it’s absorbed, where frequency is the pitch of the sound. 

 

Our results demonstrate that as the foam gets thicker, the absorbency rate is higher at lower frequencies, allowing more noise to be absorbed. 

 

The Budget, Morton and Concept acoustic partitions use a layer of 12mm foam, Following the yellow line, these screens are most efficient at a high frequency. 

 

Our Delta & Nova acoustic screens are part of the premium ranges and include a double layer of the 12mm foam to create the 24mm thickness on both sides of a solid core. With the inclusion of thicker foam, lower frequencies are absorbed at a quicker rate and excel in the mid range too.
