How plants reduce noise levels indoors
Many buildings serve purposes other than just giving us a roof over our head for shelter. Buildings such as hotels, offices, retail stores, medical facilities, etc. seek to offer inhabitants a sense of calmness, refuge and tranquility from the hustle and bustle elsewhere. This helps people want to stay in the buildings longer, to shop more, relax more, linger, have a bite to eat, concentrate with ease and more.
However, noise often abounds in buildings through phone chatter, children shouting or crying, footsteps on hard floors, unwanted conversations in adjacent cubicles, printers, copiers, HVAC systems…the list goes on and on. This noise is distracting, interruptive, makes employees less productive, reduces privacy, and can taint the customer experience. One way to create a welcoming, stress-free environment is through reducing this unwanted noise in buildings.
Plants have many known benefits to their environs and the people in them. Noise reduction is one of those less-known benefits of plants. Plants are used in many applications to reduce noise. One major example is plantings along freeways to help reduce the amount of noise distributed to adjacent communities. Plants can also greatly reduce unwanted noise inside buildings.
Plants absorb sound
How do plants reduce noise? There are a number of ways plants can reduce noise. One way is through sound absorption. Plant parts such as stems, leaves, branches, wood, etc. absorb sound. Rough bark and thick, fleshy leaves are particularly effective at absorbing sound due to their dynamic surface area.
Plant Factors that affect sound absorption:
Number of plants (the more the better!)
Size of the plant(s)
Surface area of the leaves and of the plants themselves
