How Perforated Acoustic Panels are Made
There are two methods for designing perforated acoustic metals. In the basic method, the perforated metal is primarily a decorative surface which hides the acoustic panel behind it. In the more advanced method, the perforated metal provides not only a decorative surface, but also provides a way of tuning out specific resonant frequencies.
The basic method works by insulating a perforated metal sheet with an absorptive material. In this method, the perforated metal provides the visible face of the surface, while the acoustic material is hidden behind in the panel's cavity.
When the sound waves pass through the perforations, the sound essentially is "captured" by the special acoustic material enclosed. This is the basics of acoustic panels. Working with Zahner engineers, your design team can develop high performance systems for acoustic panels. It is recommended that designer seeking a custom acoustic metal system consider developing the project using Design Assist procurement. This procurement option provides a path forward for pricing and detailing the specifics of a design to ensure a smooth project delivery.
