Building with earth - Gernot MINKE (1)

Special acoustic green bricks
6.28
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.
