Using Aluminum Panels to Optimize Soundproof Booth Acoustics

Application Scenarios

In environments where clean audio capture is critical—like radio stations, dubbing studios, and mobile voice booths—perforated aluminum sheets offer both structural and acoustic advantages. These sheets are installed inside soundproof booths to improve noise absorption and reduce standing waves. Studies by the Acoustical Society of America confirm that properly installed perforated metal sheets with backing material can outperform traditional wooden panels in small acoustic enclosures.

Specifications and Parameters

Panels are manufactured from 1100 or 5052 aluminum, ranging in thickness from 1.0mm to 2.0mm. Perforations typically have a diameter of 2–3mm with 20–30% open area. Combined with high-density fiberglass or polyurethane foam, they meet ISO 11654 and ASTM C423 sound absorption ratings. To suit studio aesthetics, finishes include dark anodizing, powder coatings, or fabric facings.

Design Considerations

Sound booths should minimize parallel surfaces and reflections. Installing Acoustic Perforated Panels across two or more surfaces prevents flutter echo and improves vocal clarity. Decorative Perforated Panels are often selected for high-visibility booths in broadcasting or voice-over studios. According to ASCE Enclosure Design Studies, combining perforated aluminum with 100mm thick backing achieves significant sound absorption across 250Hz–4kHz.

Industry Standards & Certifications

Sound booths featuring aluminum acoustic systems typically comply with:

• ASTM E90 – Transmission Loss Tests

• ISO 10140 – Laboratory Acoustics Evaluation

• ASA Speech & Voice Capture Guidelines

• Architectural Digest – Studio Sound Engineering

• ASCE Compact Enclosure Standards

Case Study

A voice-over agency in Toronto installed four new recording booths for simultaneous translation work. Each booth was lined with aluminum noise-dampening panels over 75mm acoustic mineral wool. Independent acoustic testing verified an NRC of 0.90 and an STC rating of 38. Flooring incorporated Anti-Slip Perforated Panels for maintenance safety and airflow. The successful results were showcased in Architectural Digest.
