JTA Health, Safety & Noise Specialists (JTA) was established in 1988 under the name of Jeremy Trotman and Associates when Jeremy left the Australian Chamber of Manufactures (ACM) to commence private practice.

Starting with two consultants and support staff, the focus was on the objective assessment of risks and the development of practical solutions.  This focus was sharpened with the challenge of developing services for the small business sector who comprised 85 percent of ACM members.


The business grew steadily over the years and the purchase of Industrial Audiometric Services in 2004 allowed JTA to increase their services to include Audiometric Testing in mobile testing units throughout Victoria.

In 2007, JTA purchased Noise Management Services and Hearing Conservation Services of Australia (both well established and recognised companies specialising in providing a larger range of noise related services and audiometric testing). The purchase allowed JTA to expand the range of noise solutions to include environmental noise assessments, building acoustics, vibration and sound prediction modelling. In addition, we increased our fleet of mobile audiometric testing units and our ability to run the WorkCover accredited three day Audiometric Screening Course.

2009 saw the introduction of Worksafe’s Work Health Check program and the development of the Health division to provide a range of health and wellbeing programs to ensure the health of both employees and the company.

JTA Risk Management (the evolution of Jeremy Trotman and Associates) and Noise Management Services operated as two separate companies for a few years. In May 2013 we decided to combine all of our services under the one banner of JTA Health, Safety & Noise Specialists, so that we could provide our clients with a totally integrated solution to their occupational health, noise and safety needs.


JTA is now one of Australia’s leading independent workplace consultancies. Whilst we may have grown over the years, our philosophy and approach to business remains the same.  We pride ourselves on our ability to understand a client’s needs and provide customised advice. Our team of specialist consultants offer pragmatic recommendations based on innovative scientific solutions and legislative compliance.

We aim to develop ongoing, lasting relationships with our clients and ensure they comply with WHS/OHS legislation. Working as partners, we find solutions to problems in consultation with one another.  We also have a strong commitment to quality and continual improvement, proven by obtaining the quality accreditation ISO 9001:2015.
