发明名称 Dispositivo de redução de ruído e método para redução de ruído
摘要 <p>A device has at least one region to be damped for the purpose of noise reduction. The at least one region may, in particular, be a wall region, for instance of an electrical device housing, and it is covered at least partially by at least one vacuum panel. In the noise reduction method, a vacuum panel is pulled by vacuum pressure against the region to be damped, so that a hollow space under vacuum pressure is formed between the vacuum panel and a housing.</p>
