This study explores the use of silver nanoparticles to enhance the durability, moisture resistance, and acoustic performance of walnut wood (Juglans regia), a key material in making musical instruments. Wood's natural sensitivity to environmental changes, like humidity and temperature, affects its structural integrity and sound quality. To address these issues, walnut wood samples were treated with AgNO3 nanoparticles at concentrations of 10%, 15%, and 20% through vacuum impregnation. Advanced analysis methods, such as SEM, TEM, EDX, FTIR, and XRD, verified the even distribution and integration of AgNPs, while TGA analysis showed improved thermal stability, delaying degradation above 150°C. Leaching tests indicated minimal silver release, suggesting strong nanoparticle adhesion and long-lasting protection. Contact angle measurements showed better moisture resistance, especially at 20%, which created a dense protective layer. Decay resistance tests confirmed the treatment
