| 總結: | Room design of open-plan office has low partitions. The characteristics of
partitions in this office type often cause excessive speech intelligibility. Excessive
speech intelligibility can cause disturbance to concentration at work (distraction)
to listeners outside of the people who talk and reduce speech privacy.
Factors influencing room acoustic condition refers to ISO 3382-3:2012.
Factors used in data analysis were sound absorption, distance between
workstations, and partition. Observed room acoustic conditions were speech
intelligibility, speech privacy, distraction to concentration at work, and
diffusiveness of sound field. The level of speech intelligibility was indicated by
parameters T30, C50, and RASTI. The level of speech privacy was indicated by
parameter of privacy distance (rP). Distraction to concentration at work was
indicated by parameter distraction distance (rD). Diffusiveness of sound field was
indicated by parameter coherence.
From value differences between scenarios, it was concluded that sound
absorption, distance between workstations, and partitions influenced the level of
speech intelligibility, speech privacy, and distraction to concentration at work.
Differences of C50 decline, by 76.9%, 24.9%, 77.4%, and 36.2%, each for scenario
1, 2, 3, and 4. RASTI decline, by 18.7%, 0.7%, 14.8%, and 12.9%. Difference in
percentage of speech privacy, by 6%, 0%, 11%, and 3%. Difference in percentage
of distraction to concentration at work, by 79%, 100%, 70%, and 80%. However,
sound absorption, distance between workstations, and partition were not proven to
influence diffusiveness and sound characteristics. This was shown in coherence
scores which were relatively similar and small standard deviation between
coherence values, which is 0.045. |
