A soundproof generator set is designed to minimize the noise generated during operation. It achieves low noise level performance through technologies such as soundproof enclosure, sound-damping materials, airflow management, engine design, noise-reducing components and silencers.
The noise level of a diesel generator set will vary depending on the specific application. The following are some common noise requirements for different applications.
Residential areas: In residential areas, where generator sets are often used as a backup power source, noise restrictions are typically more stringent. Noise levels are usually kept below 60 decibels (dB) during the day and below 55dB at night.
Commercial and office buildings: To ensure a quiet office environment, generator sets used in commercial and office buildings are usually required to meet specific noise level to ensure minimal disruption to the workplace. During normal operation, the noise level is usually controlled below 70-75dB.
