| Outline of Final Research Achievements |
The main purpose of this project is to develop a silent spot generation system, which realizes comfortable sound environment for users who stay under terrible loud acoustic noise environment like inside factory. To do this, the silent spot generation system creates comfortable sound environment for users who can acoustically take a rest. In order to realize this system, we have developed silent spot generation systems using parametric array loudspeakers, which have super directivity feature and deliver sound to a limited area, and using virtual sensing technique, which allows error microphones to locate at an appropriate position where does not avoid user's convenience for their works and activities. The effectiveness of the developed systems has been demonstrated through some simulation and experimental results.
