Innovation in acoustic surveying

DREAMSys (Distributed Remote Environmental Array & Monitoring System) is a project to develop a new measurement-based approach to environmental noise monitoring and mapping using novel sensors.

DREAMSys is a collaborative project involving research and technology organisations, manufacturers and environmental noise specialists. It is sponsored by the Technology Strategy Board through the Technology Programme.

The Technology Strategy Board is a business-led executive non-departmental public body, established by the Government. Its role is to promote and support research into, and development and exploitation of, technology and innovation for the benefit of UK business, in order to increase economic growth and improve the quality of life.
