Increase
in complaints of residents about noise problems in traditional timber-framed
dwellings in Turkey has necessitated identification of sound transmission
problems. The airborne sound transmission characteristics of interior wall components
in traditional timber-framed dwellings (Ankara, Turkey) were examined by
in-situ acoustical measurements and simulation analyses. The existing wall components
under examination were found to have insufficient airborne sound reduction
index (Rw) values with respect to specified criteria. Comparison of
in-situ and simulated data has shown that inherent construction features, such
as using mudbrick infill and wooden lath within the traditional wall frame, contribute
to the overall sound insulation performance of original wall components. In case that the dwelling units/spaces are used as meeting rooms,
office rooms or hotel rooms, some acoustical improvements in existing wall
components are needed and demountable/reversible attachment with minimum
interventions are necessary. The performance of several wall configurations
suggested in the study was summarized to be guiding particularly for the improvement
of airborne sound insulation of traditional timber frame wall sections and
their renovations.
