Noise silencer design using triply periodic minimal surfaces

Abstract

Noise reduction is a problem of great global interest, as we are surrounded by machines that produce noise emissions in one way or another. The 20th century saw the start of a strong development in noise reduction methods, with different methods being developed over the years, but the greatest advances in their application have been seen in recent decades. The proposed solution aims to solve the limitations of classic noise attenuators by combining two effects, destructive interference and Helmholtz resonator, and introducing a slightly atypical geometry compared to classic designs. The proposed geometry was mathematically defined a long time ago, but in recent years it has become of great interest in various fields, from CO2 capture to heat exchangers
