Abstract
Additively manufactured (AM) titanium products are increasingly being used in the aerospace industry where the acoustic-mechanical performance is of importance. However, the acoustic performance of AM Ti6Al4V and Ti6Al4V ELI (Extra Low Interstitial) has received limited attention in literature. Accordingly, this study investigates the sound absorption coefficient (⍺) and Sound Transmission Loss (STL) of both Ti6Al4V and Ti6Al4V ELI samples manufactured using Selective Laser Melting (SLM). Furthermore, the potential of developing Ti6Al4V alternatively shaped micro-perforated panels (MPP) within a frequency range of 400 to 1600 Hz is also explored
