Development of an Acoustic Enclosure for the Large Low-Noise Transformer
저소음 변압기용 조립식 철판 방음실 개발
- Published : 2007.07.18
Abstract
An acoustic total or partial enclosure is widely used to reduce the sound pressure level propagating from a noise source. However, the performance of the acoustic enclosure is decreased by its inherent limitations such as temperature rise or acoustic pressure build-up inside the enclosed acoustic field. In this reason, an acoustic enclosure consisting of a silencer and absobent panels with acoustic resonators is studied to reduce the transmitted noise from a transformer. Large sound-attenuation is expected by applying the enclosure to the large transformers in a substation.
