Reducing Indoor Noise Levels Using People�s Perception on Greenery

Employees working in cubicles of open-plan offices
in Indonesia were studied in regard to their perception on the
ability of indoor greenery to reduce noise levels. Sansevieria
trifasciata and Scindapsus sp were used. Each was placed in the
cubicle and noise levels were measured without plants, with
Sansevieria, and with Scindapsus in place. The meters showed
very insignificant difference. However, responses to surveys
indicated a perception of lower noise in the presence of greenery.
This seemed to be supported by prior knowledge and
preconception and may be useful in creating a �quieter� indoor
environment.
