Analisis Karakteristik Akustik Dan Dinamik Micro-Perforated Panel Dengan Struktur Honeycomb Mengunakan FEM

This study focuses on the discussion of correlation acoustic and dynamic characteristics hybrid panels, namely Micro-perforated Panel (MPP) Honeycomb (HC) structures. Acoustic in experimental studies are obtained by sound absorption coefficient Sound Transmission Loss. Meanwhile, mode frequency response analysis numerical simulation methods. The results these two serve as a benchmark for development data studies/analysis. purpose this is to obtain using through finite element method. study/analysis overcome drawbacks testing. weakness from that stages complicated require very large amount money. method was carried out Ansys 2019 R3 program. methods simulations Numerical panel provides efficiency at testing stage. have similarities range high low values soundtransmission loss.
