ShowTex is a worldwide leader in inventing, manufacturing and installing innovative flame retardant fabrics, tracks and motion control systems for achieving the creative vision of theatre, event and entertainment professionals.
Amazing Stage Fabrics in Motion
The ShowTex acoustics department specializes in controlling sound conditions of architectural environments, in the broadest sense. They choose the perfect combination of flame-retardant fabrics, recycled baffles and acoustic panels to offer the ultimate noise-controlling solution for any given venue, however big or small.
The team was called in to enhance the acoustic qualities of a small office space, which primarily consisted of sound-reflecting materials. The combination of concrete, glass and epoxy caused a reverberation time close to 2 seconds, which complicated meetings and made it very difficult to talk on the phone.
Although reverberation is not the only deciding factor when it comes to improving a room’s acoustics, it is a great reference that is fairly easy to measure. ShowTex therefore started off by measuring the reverberation time on various locations within the room and calculated an average time of 1.5 seconds.
MATERIALS USED IN THE ROOM
|Average RT30 = 1.50 seconds *|
No less than 8 Acoustic Panels were installed against the ceiling of the office, flush with the industrial cable tray to meet the aesthetic demands of the client.
The panels were custom-made from melamine foam and finished with white Molton CS fabric, resulting in a 28% drop in reverberation time!
But it didn’t stop there. As functionality and aesthetics go hand in hand, ShowTex also provided an impressive print on Universal 250 mounted in a Double Print Frame Profile.
The printed fabric offers a functional solution that adds a unique vibe to the space. Backed by 4cm of sound-absorbing material made out of recycled cotton remnants, it offers good acoustic qualities for absorbing primarily high frequencies. This setup resulted in a new average of 0.76 seconds!
Overall, ShowTex reduced the reverberation time in this office with no less than 49.3% and transformed the hollow room into a decent office space that offers the ideal acoustics for organising meetings and making phone calls. Choosing the right acoustic enhancements can thus easily bring back focus, silence and speech intelligibility to any space!

*The reverberation time (or RT60) describes the time it takes for the sound to decay by 60 dB after the sound source is removed. As this can be difficult to achieve in an everyday environment, it is more common to use the RT30. This is based on the time taken for the sound to decrease by 30 dB, and is then extrapolated to a decay curve of 60 dB.
