Description:

In the field of industrial active noise control, one of the main problems is generating a sufficiently intense cancelling sound field. An ideal source will have high output, low harmonic distortion and be effective over a narrow frequency range. It should also be optimised to have a maximum output in a duct. A flat plate loudspeaker is currently being investigated. This project will involve testing and modification of the current design and the development and testing of alternative designs.
