Acoustic Panels
Engineered structures designed to control sound behavior through absorption, diffusion, or reflection, serving as essential components in acoustic treatment and noise control applications.
Acoustic Panels
Acoustic panels represent a cornerstone technology in acoustic design, combining material science with practical sound control solutions to modify the acoustic properties of spaces.
Basic Principles
Function
Acoustic panels operate through three primary mechanisms:
- sound absorption of unwanted frequencies
- sound diffusion for even distribution
- reflection for directed sound control
Core Components
- Absorptive core material (mineral wool, fiberglass, or foam)
- Protective facing (fabric, perforated wood, or metal)
- mounting systems for installation
- acoustic membrane (in specialized designs)
Types and Applications
Absorptive Panels
- Reduce reverberation time
- Control room modes
- Manage flutter echo
- Enhance speech intelligibility
Diffusive Panels
- Create sound scattering
- Break up standing waves
- Maintain acoustic energy while preventing direct reflections
- Support spatial acoustics
Hybrid Designs
- Combine absorption and diffusion properties
- Feature variable acoustic impedance
- Incorporate resonant absorbers
- Enable tunable acoustics
