JAKARTA, KOMPAS.com – Plant placed indoors has a variety of benefits ranging from filtering the air, to providing shade and a beautiful element of decor.
In fact, quoted from Good and Good, Thursday (9/12/2021), some plant able to repel insects and can absorb sound or natural noise cancellation.
“Plants and trees have been used for years as a traffic barrier and another source of urban noise pollution,” says Gladys M-Curtis, plant scientist for Garden Safe, a pest control solutions company.

“Trees are planted along the highway to help reduce the amount of noise that spreads across the surrounding community,” he said.
In addition, research shows that vertical garden attached to the exterior of the building also helps protect against noise and reduces sound penetration.
Sound absorbing plant also works indoors. M-Curtis notes that they can reduce noise on an open floor plan, be it in your home or office.

To achieve this efficiently, he says, plants should be placed around the perimeter of the space, and larger planters should be used, as studies have shown that a combination of porous soil and plants provides the best sound-absorbing capacity.

That said, the amount of noise reduction is proportional to the number of plants. In other words, the more noise there is, the more plants you need to absorb the sound.
“Although plants do not have recognizable organs designed to receive sound vibrations, such as the eardrum in animals, biological evidence suggests that plants are highly sensitive organisms that generate and receive sound signals from the environment,” M-Curtis said.
Specifically, he adds, plants interact with incoming sound waves (sound waves traveling toward something) in three different ways — deflection, refraction, and absorption — and produce noise cancellation from the environment.
“Plants can deflect incoming sound energy through the vibrations of their flexible structure, thereby reducing the intensity of the incoming sound,” said M-Curtis.

“Refraction is when a sound wave passes through a plant obliquely and appears with a change in direction and speed of propagation,” he added.
And lastly, plants can absorb sound waves through leaves, branches, trunks, and bark of trees and convert sound energy into chemical energy for physiological processes.
So, plants not only absorb sound for our benefit, but sound also benefits the plants themselves in many ways.

According to M-Curtis, sound stimulates plant growth, promotes seed germination, induces plant defense responses against pathogens, delays fruit maturity, increases stress tolerance, and increases photosynthesis, the process by which plants convert sunlight into food.
While all plants have the ability to muffle noise, some types are more effective than others.
“The speed at which plants absorb sound correlates with plant density and size, leaf surface area and leaf orientation, and plant species,” said M-Curtis.
Here are 5 of the best sound-absorbing plants to place in your home, both indoors and outdoors.

“Begonia rex is beautiful and dramatic capable of absorbing up to 97 percent of sound energy that comes,” said M-Curtis.
She adds that these plants make great additions to a shaded deck, patio garden, rooftop garden or balcony, and they can also be grown indoors.
This green plant, also known by its Latin name Nephrolepis exaltata, with sword -shaped fronds and serrated leaf blades, can grow up to 90 cm.
As for the noise-canceling capability, pakis boston can absorb up to 98 percent of the acoustic energy that occurs.

Baby’s tears are one of the ornamental plants that can be planted in water. This plant has many small leaves that spread out and form tight but smooth furrows along the stem.-
3. Baby tears
“Baby’s tears are perennials that creep, form mats, and are evergreen grown for their ornamental foliage,” says M-Curtis.
Despite its small leaves, it can absorb up to 90 percent of sound in the audible frequency range.
4. Ficus
“This is one of the key species, or one that interacts strongly with other species, and has a large impact on its ecosystem compared to its abundance,” M-Curtis said.
Ficuses can also be very large, reaching 4.5 to 9 meters for tree varieties and giving them an advantage in sound absorption.

5. Peace lilies
Besides being great at reducing noise, M-Curtis says peace lilies are also known to remove indoor air pollutants.
Not to mention that this evergreen ornamental plant is very beautiful to look at, with elephant ear-shaped flowers and shiny dark green leaves. And, it gets bonus points for being relatively pest free.
