The Sound Port: Development of a bi-directional sound transducer
The Sound Port is a conceptual telecommunications device which allows the free movement of sound between two remote rooms. It creates the illusion that the two rooms are in fact adjacent with a hole in their adjoining wall. In one approach to realising this conceptual device it would be useful to have a sound transducer that could simultaneously produce and detect sound. The aim of this project has been to develop such a device.
The research has analysed and modelled the performance of existing loudspeakers both in normal use and in the reverse direction. The results have led to a possible design for a bi-directional transducer. Experimental results suggests that the concept is valid but reveal practical difficulties.
