| dc.description.abstract | It is generally acknowledged that speech related noise is a common distractor in many work environments, e.g.,
open-plan offices. There are many studies and some standards that address these noise related issues, but
they generally do not consider sound propagation through corridors. This study investigates how certain spatial
arrangements of ceiling absorption affect the spatial decay rate of speech-weighted A-weighted sound pressure
levels and speech transmission indices (STI) in a full scale corridor and in a small model tube. Results show
that while most of the configurations tested behave similarly, a transverse arrangement of absorptive material
has the potential for increased attenuation, especially in the far field, and decreased distraction distance (where
STI£0.5, ISO 3382-3 2012). These findings have relevance for design of corridors, not only in office buildings,
but for absorptive treatment of elongated spaces in general | en_US |
