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.
