摘要

Improvements introduced in the construction of hollow walls interceptors of the sound propagated in the air and sound insulators propagated in the specially removable bodies that have two parallel vertical plates arranged at a certain distance from each other characterized because the two plates are joined together by means of columns verticals spaced apart from one another and furthermore by means of local spacing bodies located between said columns, the latter being composed of at least a part of their length joining both plates of an acoustic material.
