Acoustics

NDY’s specialist acoustics division offers a range of acoustical consulting services internationally. We are consistently acknowledged as one of the best practitioners in this field.

We have been providing specialist acoustic services internationally since the mid 1990s and our expanding group of acoustic engineers and scientists have over 150 years of combined professional experience. Our acoustics specialists focus on all aspects of acoustics, including architectural and specialised spaces, environmental noise impact assessments and the physical assessment of noise and vibration.

NDY is a member firm of the Association of Australian Acoustical Consultants (AAAC) with quality assurance and environmental systems externally accredited to ISO 9001:2008 and ISO 14001:2004 respectively.

As an international acoustics consultancy, NDY aims to provide quality design and innovation in alliance with its clients to provide the best possible outcomes.

In parallel with NDY’s other disciplines, acoustics can achieve first rate outcomes effectively and economically. Our philosophy is to minimise material and operating costs over the life of the building, not engineer value out with conservative “belt and braces” first-order models. We do this through early engagements, higher-order statistics and above all, a comprehensive, researched approach.

With the ability to draw on resources from both national and international offices, NDY has a uniform approach to the successful delivery of acoustic services that incorporates high levels of expertise, innovation through research and development, solid understanding and development of computer software, and access by all staff to the knowledge and field experiences of the company as a whole.
