Two types of plants were used in a study to see employee perceptions and facts of plants in reducing indoor noise level, i.e. Sansevieria trifasciata and Scindapsus sp. Each type were planted in containers and placed inside cubicles of two offices. The noise levels were measured using sound level meters and taken in 3 periods, i.e. without plants, with Sansevieria, and with Scindapsus in place. Questionnaire surveys among employees and leaves absorption coefficient (α) measurement were also conducted. Both leaves showed significant α at high sound frequencies, i.e. 0.6. But, the meters showed very insignificant noise difference before and after plantings, i.e. only 3 dB with no regard of plant types. Fluctuation of 3 dB is hardly noticed by human hearing instruments. Whilst, the surveys showed contradictory results, 60% I1st office) and 22% (2 st office) of employees agreed that noise level was lowered after plantings. These showed that indoor plants might create more pleasant environment for employees to feel undisturbed by noise, where actually the noise remained at similar levels.
