| Abstract: | In order to inform the warning of evacuation when traffic accident and/or fire occur in tunnel, loudspeaker system is planned to be installed in it. The purpose is to predict whether the system can meet the requirements of basic speech articulation under the disadvantageous conditions of high background noise and long reverberation time. |
| |
| Keywords: | tunnel speech articulation Speech Transmission Index(STI) acceptable noise level |
