From 75dB to 65dB: Kawo Company's Whitepaper on Noise Reduction Technology for Silent Diesel Generator Sets
The main noise sources of diesel generator sets include:
Mechanical noise (engine piston/gear movement)
Exhaust noise (high-temperature, high-velocity airflow)
Cooling fan noise (air turbulence)
Acoustic Encapsulation Design
▸ Double-layer galvanized steel soundproof enclosure (1.5mm + 2.0mm)
▸ 50mm high-temperature-resistant sound-absorbing lining (NRC ≥ 0.95)
Exhaust System Optimization
▸ Three-stage impedance composite muffler (insertion loss ≥ 35dB)
▸ Corrugated pipe vibration-damping connection
Active Noise Control (Optional)
▸ Microphone array real-time monitoring + reverse sound wave cancellation
| Model | Open-Type Noise | Silent-Type Noise | Reduction |
|---|---|---|---|
| 100kW | 82dB(A) | 63dB(A) | 23% |
| 500kW | 88dB(A) | 68dB(A) | 22.7% |
▶ Application Scenario: Hospitals (additional customization required for WHO nighttime noise limit zones of 45dB)
