Acoustic Specification
Sound Reduction values for walls are in accordance with BS 2750.

• The Average Sound Absorption Co-Efficient for walls is in accordance with BS 3638 : 1963.


• Sound Absorption refers to the amount of airborne sound energy absorbed on the wall surface adjacent to the sound.


• Sound transmission loss is the total amount of airborne sound lost as it travels from one side of the wall or floor to the other.


• Impact Sound Isolation refers to the number of decibels lost through a wall or floor from standardized impact.


• Harney Masonry dense concrete blocks are particularly suitable for the reduction of airborne sound transmission and can be used to construct dividing walls in buildings.

Air Permeability
The air tightness of a structure has a direct impact on the natural ventilation rate. The unnecessary air leakage of buildings in arbitrary locations leads to occupant discomfort and higher energy consumption.

Buildings should be designed and constructed to provide minimal air infiltration except in locations which are part of the building design.
