Soundproofing element includes a first sheet including a flexible material and a second sheet consisting of flexible material. The sheets are positioned at a distance from one another and at least two chambers are formed between said sheets for receiving a filler medium. The first sheet and the second sheet are connected by connection element located on opposing surfaces. Appropriately, the connection elements have at least one connecting length consisting of flexible material. The soundproofing element is constructed simply and robustly. When empty, it is easy to handle and transport. In addition, the inventive soundproofing element is suitable for filling with a high-density filler medium, for example sand or similar material.
