Existing timber stud partition, or any other wall type constructed with a 102 mm (4 inch) cavity depth.
1. Many professional installers use a "doughnut' of compliant material, which can be inserted as a tight fit between the two surfaces of the partition or into the
wall cavity. The length of the internal surface of the strip of material determines the 'enclosure' volume. For each model, cut the strips into lengths listed in the
table below, insert into the cavity, and join to form a ring that will ensure the correct volume - see Fig : 12
