The sound insulations of studio doors. Part 2: Door seals
Abstract
The acoustic performances of a range of proprietary acoustic door seals were measured in the Transmission Suite. The seals were fitted to a standard BBC lead-cored door hung in a purpose-built blockwork wall. As a result of the work, suitable plant-on magnetic perimeter seals and drop-down threshold seals are recommended. The use of these seals will simplify the existing door frame design and should reduce costs without compromising the acoustic performances. The sound insulations were also measured of a range of door blanks with the intention of improving the performances. This work is documented in a companion Report (BBC RD 1994/14).
