About

ALN Acoustic Design Ltd is a London-based consultancy specialising in sound, acoustics, and noise control within the built environment. We focus on acoustically critical spaces such as performance venues, cinemas, and recording studios where success is defined by sound quality. Our approach combines technical expertise with practical insight, delivering effective solutions to complex acoustic challenges.

The practice was founded by Arthur Lewis-Nunes, an experienced consultant with a robust background in physics and acoustic design. Arthur previously worked at renowned firms including Bickerdike Allen Partners and Max Fordham LLP where he provided the acoustic design for numerous high-profile projects. He holds a degree in Physics from the University of Manchester and a Masters in Acoustics from the University of Salford and is a corporate member of the Institute of Acoustics.

Services

Building Acoustics

We provide expert guidance on all aspects of building acoustics, supporting both refurbishment and new-build projects of all scales. Building acoustics involves the design and control of sound within spaces - what can be heard, how it sounds, and just as importantly, what can't be heard. This ranges from insulating housing against traffic noise to enhancing speech clarity in lecture theatres and auditoria.

By collaborating closely with architects, engineers, and other members of the design team, we develop solutions that are practical, well-integrated, and effective. Our approach combines rigorous acoustic testing, advanced computer modelling, and a wealth of hands-on experience to consistently deliver optimal results.

Performance Spaces & Studios

Whether it's spoken word, live music, or studio production, sound should be experienced in an environment that enhances its clarity, richness, and emotional impact. We provide specialist acoustic design services for performance venues, recording studios and rehearsal spaces - ensuring each space supports its intended use to the highest standard.

Our work includes new-build projects as well as the refurbishment of existing spaces, where we resolve acoustic shortcomings or protect established performance quality during renovation. We offer detailed guidance on sound isolation, room acoustics, and environmental noise control. This includes the design of low-noise recording environments, neutral-response mixing rooms, and enhanced insulation for spaces where loud instruments or amplified sound could otherwise disrupt neighbouring areas.

Through careful integration with the wider design team, we help create acoustically optimised environments that meet both technical requirements and artistic expectations.

Acoustic Measurements

We offer a comprehensive range of acoustic measurement services, including long-term environmental noise monitoring, vibration surveys, and detailed room acoustics testing. Our measurements support both compliance and design refinement, providing accurate, high-quality data to inform decision-making at every project stage.

Noise Assessments

We provide detailed noise impact assessments to support planning applications for a wide range of developments, including residential schemes, licensed venues, commercial premises, and building services plant installations. Our reports are tailored to meet the requirements of local authorities and aligned with relevant local, regional, and national noise policy.

In addition to assessment work, we offer expert advice on achieving compliance with noise-related planning conditions and environmental standards, helping to streamline the planning process and minimise risk of delay.
