Effect of reverberation on speech intelligibility, logatom test “in situ”
The influence of acoustic parameters of lecture halls is essential for the quality of reception and the understanding of the content. One of the basic acoustic parameters is the reverberation time in the room. The study demonstrates that the room which is not properly designed for acoustics, causes difficulty in understanding the delivered text. Selected acoustic parameters were analyzed, such as reverberation time, acoustic background, and delivered text intelligibility. A possible solution was proposed, using reflecting and absorbing surfaces appropriately positioned in the room.
