Alex Barker is a Consultant with Marshall Day Acoustics' Wellington office

Since joining Marshall Day Acoustics in 2008, Alex has gained experience in many fields of acoustics including environmental noise modelling and measurement, room acoustics, sound insulation and building noise control.

Alex has consulted on the acoustic design of projects such as schools, courthouses, cinemas, offices and apartment buildings.  He has prepared acoustic assessments as part of consent applications for a variety of developments, and is skilled at conducting measurements for the purposes of assessing workplace noise exposure, building sound insulation, room acoustics, speech transmission indices and industrial noise monitoring.

After completing his Master's Degree in Physics at Otago University, Alex joined Marshall Day Acoustics' Auckland office before relocating to Wellington in 2009. Alex's involvement in acoustics came as a result of converging interests in science and music - in addition to Physics, Alex has an active interest in music performance and recording, and in the design of electronic and electroacoustic instruments.
