Why Choose AquaSonic™ PHCH Low Frequency Super Absorber?
The AquaSonic™ PHCH Low Frequency Super Absorber is engineered for ultra-efficient low-frequency sound absorption using a microperforated facesheet and precision-tuned corrugated core. With absorption peaks reaching up to 0.99 at ~580 Hz (60 mm variant), it delivers exceptional performance while maintaining a subwavelength profile—just 1/10 of the wavelength at resonance.
Its construction features:
-
Panel Thickness Options: 20mm, 40mm, 60mm
-
Facesheet Thickness: 1–4mm with customizable microperforations (0.4–1.3mm)
-
Corrugation Layer: ~1mm thickness with additional perforations
This configuration enables broadband absorption across ~290 Hz to ≈1160 Hz, covering over two octaves with α > 0.5. The panel’s lightweight composite build (4–8 kg/m²) ensures easy handling while allowing tuning through thickness, hole size, material type, and perforation geometry.
Designed for durability and adaptability, AquaSonic™ PHCH offers:
-
High structural rigidity comparable to honeycomb sandwich panels
-
Impact resistance suitable for load-bearing environments
-
Corrosion-resistant materials for marine and industrial use
-
Customizable materials (GFRP, carbon fiber, or marine-grade metal options)
Installation is flexible with adhesive bonding or mechanical fixing, and perforation patterns can be tailored for both acoustic performance and aesthetics.
Ideal applications include:

AquaSonic™ PHCH uses a microperforated facesheet combined with a tuned corrugated core. This design enables peak absorption up to 0.99 around ~580 Hz and maintains broadband performance across ~290–1160 Hz, even at subwavelength thickness.
[/fusion_toggle][fusion_toggle title=\”Can the panel be customized for different environments or frequencies?\” open=\”no\”]
Yes. Key parameters such as panel thickness (20/40/60mm), facesheet thickness, perforation size, corrugation geometry, and material type can be adjusted to meet specific acoustic targets and environmental conditions.
[/fusion_toggle][fusion_toggle title=\”What materials are available for construction?\” open=\”no\”]
The absorber can be manufactured using GFRP, carbon fiber, or marine-grade metals. The choice depends on performance needs, weight limits, corrosion resistance, or structural requirements.
[/fusion_toggle][fusion_toggle title=\”How is the AquaSonic™ PHCH installed?\” open=\”no\”]
Installation is simple and adaptable. Panels can be mounted using adhesive bonding or mechanical fixing, depending on the surface, environment, and load conditions.
[/fusion_toggle][fusion_toggle title=\”Where can AquaSonic™ PHCH be used?\” open=\”no\”]
It is ideal for marine vessels, offshore installations, industrial facilities, machinery enclosures, research labs, and any setting requiring low-frequency noise control with high durability.
