Our Story

Engineering-led acoustic consultancy, founded on practical solutions and built on trusted relationships.

David Cawley, founder and Managing Director of Allegro Acoustics

Founded on engineering depth

Allegro Acoustics was founded in 2010 by David Cawley, a Chartered Mechanical Engineer with a Masters Degree in Applied Acoustics. He recognised that organisations facing complex noise and vibration challenges needed more than measurements and reports, they needed practical engineering advice, clear communication and noise control solutions that could be implemented in the real world.

From our base in Dublin, and now a UK office in London, we have grown into a team of specialist acoustic engineers, architects and consultants serving clients across Ireland, the UK and Europe, working on some of the most demanding construction, industrial and infrastructure projects in data centres, life sciences, energy and manufacturing.

We protect organisations from noise risk through practical engineering, robust design and reliable solutions.
