Research

Subacoustech prides itself in being in the top echelon of competence and scientific credibility in its field. It has also achieved a reputation for "getting things done" even with the most arduous research tasks, and as interest grows in the field of underwater noise, Subacoustech's experience and creation of ideas is ever increasing.

Many or the research areas in which Subacoustech have been involved have been published in peer reviewed scientific journals. Click here to go to our publications page to download any papers that you find of interest.

Underwater Acoustics

Subacoustech has over 25 years of experience in the field of underwater acoustics and has undertaken research and consultancy projects for the former Defence Evaluation and Reserach Agency (DERA), who are now DSTL and QinetiQ.

Seismics

The oil and gas industry use arrays of high pressured air guns during exploration, creating high impulse noise underwater. Subacoustech has been involved in measuring the noise from seismic surveys in partnership with marine biologists specialising in fish and marine mammal biology.

Underwater Hearing

The role of noise as a pollutant as a source of industrial injury is well defined and has standards in air, but not underwater. Subacoustech has been involved in defining the efficiency of human hearing underwater, so that the standards for noise exposure may be applied.

Audiograms and dB_ht

For the past years, Subacoustech have been researching the hearing abilities of different species. This information, in the form of audiograms, can then be used to evaluate hearing thresholds (ht) for that species. These thresholds are invaluable in assessing the actual effect that underwater noise may have on that species.
