The structure-borne and air-borne sound insulation were measured of three variants of a “floating” asphaltic floor which were applied on a part of a ship’s deck with an area of 12 m2.
A mechanically acceptable variant containing rather soft glass wool proved to have excellent features with respect to noise abatement. An investigation aboard a ship concerning the latter type showed that mechanical short-circuits may have a great influence on the structure-borne sound insulation. Comparisons with a deck covered with a 20 mm solid layer of asphalt are also made.
