THE SOUND ABSORBING OJBECT
"Artifical Forest" is an architectural object designed to address noise pollution in modern environments and create a calming effect. The project utilizes coffee grounds and construction waste as its primary materials, symbolizing the waste produced in big cities on a daily basis. In the fast-paced urban lifestyle, where we consume copious amounts of coffee to stay alert and witness the relentless construction of towering buildings, it serves as a reminder of the increasing anxiety and mental unease prevalent in such environments. Through this project, I aim to propose a solution for building tranquil living environments using these waste materials, reducing the mental instability caused by noise pollution in urban areas.
The key component of the "Artificial Forest" is an artificial stone made of jesmonite and coffee grounds. This stone serves as a Helmholtz resonator, a traditional structure used for sound absorption and amplification since ancient times. The dimensions of the hollow resonator body inside each stone and the size of the hole in the middle are carefully calculated based on the Helmholtz equation.
Two different types of stones are employed to absorb high and low frequencies separately. The stone with a larger hole is specifically designed to target 250 Hz, which is the average frequency of common noise sources found in office settings, such as HVAC rumble or machinery vibrations. The stone with a smaller hole is adjusted to absorb the 2000 Hz range, which encompasses conversation noise, keyboard typing, and ringing phones. Additionally, the stones feature a nature-like marble texture, achieved by incorporating coffee waste, to mimic the calming effect and earthy visual aesthetics of a natural forest.
To optimize the sound-absorbing function, the "Artificial Forest" offers flexibility in designing the forest by adjusting the ratio of the two types of stones based on the specific noise characteristics of each urban working environment. Additionally, the incorporation of metal waste into the structure enables the creation of a cohesive forest-like arrangement, enhancing the overall tranquil atmosphere.
By repurposing waste materials and incorporating them into the design of the "Artificial Forest," the project aims to provide a solution for reducing noise pollution and creating harmonious urban spaces.
