Room isolation and noise canceling generators swing requires thorough isolation, to prevent premature failure. Cable connection should be soft. The main sources of noise are: intake system, exhaust gas turbocharger, combustion noise, cooling fan and secondary vibration. Noise noise propagation distance depends on the size and noise level around, most people find it difficult to distinguish the sound of 3dB (A) the difference between the two noise sources, however 6dB (A) was 2-fold difference in noise intensity, high-frequency noise is easy to hear precise testing requirements of environmental noise generators at least less than 10dB (A). If the system noise is too loud, it may exceed the allowed range of local regulations. Engine room crew from the impact. Near the area: a distance greater than 2 times the noise field, the noise level changes greatly; free area: Estimated noise level - from the 2 fold decrease 6dB (A); reflection region: free area, near the reflection region. Noising measures local regulations often dictate neighborhood noise restrictions at 40 ~ 50dB (A), because after the treatment is very expensive, noise problems for neighboring generators need to be planned in advance. When the generator set is running, the engine room required hearing protection facilities, Longgang generator rental, noise should meet OSHA standards. Noise source to the recipient should be ready isolation, establish realistic goals, measure and predict noise levels, noise cancellation assess needs. Effective noise cancellation depends on the hardness of the walls, the effective open area, showing the noise channel, sound-absorbing materials used, reflection noise and noise leakage. The net figure is usually a good cover to reduce air flow through the housing. Measures to eliminate noise scene are: ① increasing access to distance. According to quickly estimate the distance increased by 2 times, noise reduction 6dB (A). ② added high-density sound-absorbing materials, changing the direction of the noise, attention harder reflective surface. It quickly estimate, generator rental near Shenzhen, two identical reflection wall will increase noise 3dB (A). In short, everything to isolate the unit.
