ABSTRACT:
A sound-damping housing suitable for use with a piece of sound-generating equipment. The housing has inner and outer housing parts, the former forming a chamber for receiving the piece of sound-generating equipment, with the two housing parts forming between themselves a second chamber for receiving a sound-damping liquid. This second chamber surrounds the receiving chamber, and suitable provision is made for allowing the piece of sound-generating equipment to be inserted into and withdrawn from the receiving chamber. By virtue of this arrangement, the sound-damping housing and the piece of sound-generating equipment may be transported separately from each other. Moreover, the liquid need not be introduced into the sound-damping housing until after the same has been transported to the place where it is to be installed, thus making it easier for the sound-damping housing to be transported.
