Abstract
This study aims to develop and analyze the performance of resonant absorbers to reduce low frequency standing waves commonly found in home studio environments. Given the economic constraints of home studio users, readily available recycled materials, such as PET bottles, were utilized as the primary absorber components. The first experiment was conducted in a controlled empty space to minimize external environmental influences and objectively evaluate the inherent performance of the absorbers. Various factors, including placement, material type, volume and the combination of viscous and porous materials, were tested to measure frequency responses and assess their effectiveness in reducing standing waves. Through this process, the most effective configuration for reducing low frequency standing waves was identified. This configuration will be further tested in a second experiment conducted in an actual home studio environment where users are present. This study presents only the results obtained from the first experiment, with practical applicability to be evaluated in future research. The findings demonstrate that resonant absorbers made from recycled materials can significantly reduce standing waves in specific low-frequency ranges, suggesting that cost-effective acoustic improvements can be achieved. These results indicate that recycled materials hold strong potential as viable alternatives for acoustic enhancement in the future.
