Early in his career, Arthur founded the Pachyderm Acoustics Open Source acoustic simulation initiative. Since then, he has worked on a wide range of building projects with architects worldwide. From 2012 to 2016, he worked as an acoustician with the Foster + Partners Specialist Modelling Group. He currently works with Acoustic Distinctions in the Greater New York. He continues to develop Pachyderm Acoustic, both to satisfy his curiosity, solve new problems that crop up in his consultancy practice, and as a tangible expression of what he has learned.
