PVC 파이프 배열을 이용한 음향 메타물질의 설계 및 실험적 검증

Abstract

The design and implementation of acoustic metamaterials have garnered significant interest for their potential in noise and vibration reduction and control. However, the process of fabricating metamaterials is often perceived as challenging and confined to specialized fields. In this study, we aim to remove these barriers by demonstrating that it is possible to design and implement acoustic metamaterials using a simple array of commonly available PVC pipes. We designed and fabricated metamaterials using PVC pipe arrays and validated their performance through both numerical simulations and experimental testing. The experiments were conducted using standard audio equipment, and the results showed consistent trends with the numerical simulations. This research demonstrates that acoustic metamaterials can be effectively realized using accessible materials like PVC pipes, providing a practical approach to noise reduction and control.
