This project involves the installation of a vertical microporous noise barrier system for an energy storage power station in Japan. The solution was designed to effectively control equipment noise generated by battery systems, inverters, and cooling units, ensuring compliance with local environmental noise regulations while maintaining a clean and organized site appearance.
Project Details
Product Type: Vertical Microporous Noise Barrier
Application Area: Around battery containers and equipment zones
Barrier Structure: Fully enclosed / semi-enclosed (customized)
Height: 2.5m – 4.0m (customized based on site conditions)
Project Challenges
Energy storage stations typically generate continuous noise from:
Cooling fans and ventilation systems
Power conversion systems (PCS)
Transformers and auxiliary equipment
The key challenges in this project included:
Strict Japanese environmental noise standards
Limited installation space
Requirement for efficient ventilation and heat dissipation
Need for corrosion resistance and long-term durability
Our Solution
To address these challenges, we provided a custom-designed vertical microporous acoustic barrier system, featuring:
1. Microporous Sound Absorption Design
The barrier panels are made of micro-perforated metal sheets, which effectively absorb mid- to high-frequency noise while maintaining airflow.
2. Composite Acoustic Structure
Outer Layer: Micro-perforated galvanized steel panel
Inner Core: High-density sound-absorbing material (rock wool)
Back Panel: Solid steel sheet for sound insulation
This structure ensures a balance between sound absorption and sound insulation performance.
3. Vertical Modular Installation
The barrier adopts a straight vertical structure, allowing:
Fast installation
Flexible layout around equipment
Easy maintenance and replacement
4. Weather Resistance & Durability
Hot-dip galvanized steel structure
Anti-corrosion powder coating
Designed for long-term outdoor use
Performance Results
Noise Reduction: Up to 25–35 dB
Compliance: Meets local environmental noise standards
Ventilation: Maintains airflow to prevent overheating
Visual Impact: Clean, industrial-modern appearance
Applications
This type of noise barrier is ideal for:
Energy storage power stations
Transformer substations
Industrial equipment areas
Generator and cooling system zones
Why This Project Matters
With the rapid development of renewable energy in Japan, energy storage facilities are becoming increasingly important. However, noise control is a critical factor for project approval and community acceptance.
This project demonstrates how microporous acoustic barriers can provide an effective, durable, and environmentally compliant solution for modern energy infrastructure.
