Styles Group, Acoustics and Vibration Specialists

Underwater noise

  • Measurement, prediction and assessment of underwater noise
  • Evaluation of potential impact zones for marine mammals and fishes

Specialist expertise

With Styles Group, you can expect comprehensive information and reliable advice on underwater noise. Our specialist fields include characterising underwater noises and understanding the impacts from anthropogenic (human-related) noise are specialist fields. We employ qualified and experienced marine scientists, so you can have complete confidence in the reports we provide.

Broad experience

In coastal and off-shore waters, the intensity of underwater noise from anthropogenic sources is estimated to be doubling every 10 years. The sources of this influence on the natural world include:

  • Pile-driving
  • Petroleum exploration
  • Construction activities
  • Boats
  • Sea-based wind and tidal turbines

Our specialist expertise and experience is relied on for:

  • Marine policy
  • Petroleum exploration
  • Renewable energy generation
  • Marine conservation

Research

Research currently underway includes an ongoing marine acoustics monitoring programme and underwater propagation studies. The aim of our monitoring programme is to build a database for long-term baseline acoustic data for the Hauraki Gulf. This programme will provide invaluable data for acoustic assessments around New Zealand and improve our understanding on the underwater acoustic environment both here and overseas as we publish the data in scientific journals.
