Outline of Final Research Achievements

To provide adequate acoustic environment without anxiety at health care facilities, we are studying the research focusing on an ambient noise and speech privacy. We had an opportunity to measure distribution of sound pressure levels at a health care facility. The result of the data analyses revealed that accurate information transition seemed difficult at several rooms. And the quality of architectural acoustics is obstructed when the working route is connected with examination room.
Although patient should concentrate to cure own illness, ambient noises make patient uncomfortable at a patient room. It is necessary to develop a new method which can perform an on-site recording and analyzing for an ambient noise with protection of all personal information. The sound sources like medical equipment and daily life noises and talker’s voices were recorded in the simulated ward, and then sound source files were processed with certain method to reduce speech intelligibility.
