Speech Intelligibility And Good Sightline For Vision In Lecture Hall Acoustics As A Determinant For Effective LearningTeaching Environment

Abstract The study investigated whether speech intelligibility from the teacher and good sightline for vision in lecture hall acoustics as determinant for effective teachinglearning environment. 300 students out of a total of 522 lecture hall seating capacity at the Federal college of Education Technical Omoku Rivers State Nigeria was used for the study. Instrument for data collection was the questionnaire that addressed what constituted indicators for speech intelligibility and good sightline for vision in lecture halls. Data was analyzed using the arithmetic mean and standard deviation and Z-test for two independent groups mean at 0.05 level of significance. The findings revealed that in the opinion of the students speech intelligibility and good sight line for vision were determinants for effective teachinglearning environment. The Z-test also indicated that there was no significant difference in the mean response scores of the students. The implication was that students were not afforded good speech intelligibility and sight line for vision. It was recommended that the internal space of the lecture halls should be carefully designed for effective distribution of speech intelligibility and good sight line for effective teachinglearning environment.
