Building with Earth: Design and Technology of a Sustainable Architecture

Special acoustic green bricks

In order to optimise the acoustic behaviour

of domed rooms, a special loam brick with

rounded corners was developed by the

author (6.27). The rounded corners and the

corbelling effect of the bricks (6.26) yield

good sound distribution, while good sound

absorption is produced by the cut-off joints

and the holes in the brick. Illustration 6.28

depicts a 6-m-high wall of unburned (green)

bricks, introduced in order to improve the

acoustic behaviour of the hall.
