Perforated Aluminum Sheet for Soundproofing Sound Booths

Application Scenarios

Sound booths require precise acoustic control to ensure high-quality voice or music recordings. Perforated aluminum sheets serve as a key component in enhancing sound isolation and reducing internal reflections. These panels are used on inner booth walls and ceilings, forming an acoustic shell that supports clean sound capture. According to the Acoustical Society of America, metal-backed perforated treatments offer predictable acoustic behavior ideal for controlled environments.

Specifications and Parameters

The typical aluminum panel used in sound booths ranges from 1.0mm to 1.5mm thick, with perforation diameters of 1–3mm and 20–35% open area. Panels are often paired with mineral wool, fiberglass, or foam behind to improve absorption. These assemblies meet ISO 11654 and ASTM E90 standards. Finishes include matte black or fabric overlays to reduce visual glare and preserve booth aesthetics.

Design Considerations

Effective booth design requires managing both internal reflections and external isolation. Aluminum acoustic barriers function as both a reflective and absorptive element when integrated with dampening materials. Acoustic Perforated Panels help control flutter echo, while Decorative Perforated Panels ensure seamless integration into broadcast studios and mobile booths. The ASCE Library recommends isolating each panel from structural vibration paths to maximize enclosure performance.

Industry Standards & Certifications

Booth acoustic systems are typically certified under:

• ASTM C423 – Sound Absorption

• ISO 11654 – Absorber Classification

• ASA Technical Reports for Enclosures

• Architectural Digest – Recording Space Design

• ASCE Soundproof Booth Design Standards

Case Study

A podcast production studio in Melbourne retrofitted four voice-over booths using perforated aluminum panels over 50mm acoustic foam. Post-upgrade tests showed a 21dB drop in internal reflections and a 0.6s reduction in reverberation time. Aluminum panels with 25% open area were coated in matte black and mounted on decoupled metal framing. Maintenance flooring used Anti-Slip Perforated Panels to ensure safety and airflow. This project was later highlighted in Architectural Digest.
