About Us

National Audiometry Services was formed by Liz Garritt in 2008. Liz is an Acoustic Consultant and Director at the established acoustic consultancy firm, S & D Garritt Ltd, of which National Audiometry Services is a trading name.


Increasing demands from the government to safeguard employees against health and safety risks, and also the potential for costly compensation claims, are concerns for many employers. It was realised that offering hearing test services to these employers could cut the risk of noise induced hearing loss in the workplace, and thereby cut the risk of compensation claims.

In February 2008 Liz completed a course in Industrial Audiometry, accredited by the British Society of Audiology (BSA). Liz has also completed a post graduate diploma in Acoustics and Noise Control and has gained associate membership of the Institute of Acoustics (IOA). National Audiometry Services was formed in 2010, specialising in audiometry and working alongside S & D Garritt Ltd to provide comprehensive solutions to workplace noise problems.
