This study examined whether the strategic placement of certain plants which provided acoustic quieting, could reduce the stress levels of participants in an acoustically noisy environment. Student participants were randomly assigned into a plant, synthetic plant, or no plant condition group and tested on two cognitive tasks. We hypothesized that participants in the loud environment with acoustically quieting plants will have lower levels of stress, as measured by heart rate, than those with a non-quieting, artificial plant, or no plants. Our results found no significant effect of the presence of live, synthetic, or no plants on participants’ heart rate during the cognitive tasks. While our study obtained non-significant results, there were noticeable trends, which were consistent with previous findings on the benefits of human-plant interactions. Further studies could help shed light on potential green methods for dealing with issues of noise and stress in the work place.
