ALN Acoustic Design Ltd is a London-based consultancy, providing advice on sound, acoustics and noise in the built environment. We specialise in acoustically critical applications, including studios, cinemas and performance facilities, whose success is judged largely by how they sound. We strive for pragmatic solutions to complex problems, and to bring clarity to what is often considered to be an obscure area of building design.

ALN Acoustic Design Ltd was founded by Arthur Lewis-Nunes, who has previously worked at Bickerdike Allen Partners and Max Fordham LLP, delivering the acoustic design for various prestigious buildings. Arthur studied physics at the University of Manchester, holds a Masters degree in Acoustics from the University of Salford, and is a full member of the Institute of Acoustics.
