1. Project Fact Sheet
Project Title: Procter & Gamble (P&G) Tianjin Manufacturing Base Comprehensive Boundary Noise Control Project
Project Location: P&G Industrial Manufacturing Park, Tianjin, China
The Problem: The Procter & Gamble (P&G) Tianjin Manufacturing Base operates as a state-of-the-art consumer goods manufacturing hub.The facility features dense arrangements of advanced automated production machinery, industrial cooling tower fans, centrifugal pump stations, and auxiliary HVAC units operating continuously 24/7. This intensive operational setup generated severe multi-source acoustic superposition noise, leading to persistent perimeter noise issues.
Measurement Location | Before Mitigation | After Mitigation |
1m from the outside of the factory boundary | 79-83 dB (A) | 62–55 dB (A) |
Impact points | 60–65 dB (A) | ≤ 50 dB (A) |
3.Key Engineering Methodologies & Noise Control Solutions
To eliminate acoustic compliance risks without disrupting daily manufacturing throughput, our engineering team executed a turnkey, custom-designed industrial noise barrier solution based on four primary pillars:
1. Custom High-Performance Composite Sound Absorption & Isolation Barriers
Addressing the broad-spectrum, low-to-mid frequency characteristics of complex industrial machinery noise, we custom-engineered high-performance composite acoustic barriers. These panels feature micro-perforated sound-absorbing metal fascia combined with high-density internal acoustic rock wool and sound insulation cores. By targeting the sound propagation path, the barriers achieve high Sound Transmission Class (STC) and Noise Reduction Coefficient (NRC) ratings, dramatically cutting acoustic energy dispersion across the site boundary.
2. Modular, Standardized & Zero-Downtime Installation
To eliminate operational disruptions, the entire acoustic fence system utilized a modular, prefabricated design. Components were manufactured off-site under strict quality control standards and rapidly assembled on-site with high structural precision. This modular approach minimized site clutter, ensured exceptional structural stability, and guaranteed zero downtime for ongoing P&G production lines.
3. Heavy-Duty Weatherproofing & Anti-Corrosion Surface Engineering
Engineered for long-term outdoor reliability in Northern China's harsh industrial atmosphere, all steel support structures and acoustic panels underwent multi-stage anti-corrosion treatments. Featuring hot-dip galvanization and outdoor fluoropolymer/electrostatic powder coatings, the barrier system exhibits high resistance to UV radiation, weathering, acid rain, and atmospheric corrosion—ensuring an extended service life and minimal long-term maintenance costs.
4. Architectural Integration & Premium Industrial Design
Recognizing P&G's commitment to modern industrial aesthetics, the physical layout and color schemeeme of the sound barrier were custom-tailored to complement the facility's existing architectural facade. The clean, modern design provides an impressive visual profile while acting as an effective environmental shield.
4. Acoustic Results
Overall Noise Attenuation: Delivered a massive 15 dB(A) to 22 dB(A) reduction in boundary sound pressure levels.
Perimeter Noise Level: Successfully stabilized overall boundary noise at ~50 dB(A), fully satisfying Class 2 industrial boundary standards.
