Application Case of Melamine Foam in Acoustic Construction of a Comprehensive Sports Complex

1. Project Background & Objectives

Project Name: Municipal National Fitness Center Project
Total Construction Area: Approximately 16,200 m²

The project includes two primary functional zones:

• Comprehensive Building: Gymnasium, table tennis hall, yoga studio and public fitness facilities
• Shooting Range: Built to provincial competition standards for professional training and small-scale events

The venue accommodates public fitness activities, professional team training, and small sports competitions.

Acoustic Challenges

• Excessive reverberation time
• Noticeable echoes
• Poor public address (PA) clarity
• Overlapping sports and crowd noise
• Communication safety risks during training
• High long-term maintenance demands

2. Material Selection & Technical Basis

• Open Cell Rate: ≥ 99%
• Density: Approx. 8.5 kg/m³
• NRC: ≥ 0.85

Key Advantages

• Superior Sound Absorption: Mid-high frequency absorption ≥ 0.9
• Inherent Flame Retardancy: GB 8624 Class B1
• Ultra-Lightweight: Minimal structural load
• Eco-Friendly: Low formaldehyde, fiber-free
• Durable: Stable performance over 20 years

3. Acoustic Design & Installation

Ceiling: Large-area acoustic panels + suspended absorbers

Walls: Rear and side wall acoustic treatment

• Modular suspension + adhesive fixing
• Integrated with original structure
• Fire-rated finishing
• Even distribution to prevent echo focus
• Short construction period
• Minimal disturbance

4. Acoustic Performance Results

5. Application Feedback

• Sports Training: Clear instructions, improved efficiency
• Events: Clear commentary, better audience experience
• Performances: Clean vocal and instrument sound
• Management: Lightweight, low maintenance, no deformation

6. Case Summary

• High sound absorption
• Ultra-lightweight structure
• Permanent flame retardancy
• Environmentally safe

This project achieved cost-effective, fast, and high-performance acoustic optimization, offering a replicable solution for sports halls and public buildings.
