Investigation of the Appropriate Reverberation Time for Lower-Grade Elementary School Classrooms Using Speech Intelligibility Tests

نویسندگان

چکیده

Because speech recognition performance is significantly lower at the age of nine or younger, acoustic standards classrooms for young children should be investigated. This study derives appropriate reverberation time lower-grade elementary school in Korea. A virtual sound field was created by computer modeling using normalized Korean schools. total five with times from 0.6 s to 1.2 were produced varying absorption coefficient ceiling. Auralized sounds synthesizing anechoic words a field. Speech intelligibility tests undertaken 20 students, aged nine. As result, it concluded that suitable schools below because test scores when RT longer than this value.

The intelligibility of speech in elementary school classrooms.

This is the second of two papers describing the results of acoustical measurements and speech intelligibility tests in elementary school classrooms. The intelligibility tests were performed in 41 classrooms in 12 different schools evenly divided among grades 1, 3, and 6 students (nominally 6, 8, and 11 year olds). Speech intelligibility tests were carried out on classes of students seated at th...

Effect of noise and occupancy on optimal reverberation times for speech intelligibility in classrooms.

The question of what is the optimal reverberation time for speech intelligibility in an occupied classroom has been studied recently in two different ways, with contradictory results. Experiments have been performed under various conditions of speech-signal to background-noise level difference and reverberation time, finding an optimal reverberation time of zero. Theoretical predictions of appr...
