| Summary: | Hybrid teaching has gained substantial interest in higher education and is anticipated to influence future pedagogical
reforms worldwide in the aftermath of the pandemic. Despite the adaptability of hybrid teaching as a flexible
instructional design, various limits have emerged. Poor sound quality was a major challenge for distant students,
impairing their ability to effectively comprehend lectures and engage in interactions with on-site peers and
instructors. Therefore, this study aims to investigate the impact of surface material design treatment on two distinct
educational approaches in hybrid classroom environments, namely lecture-based and collaborative learning. This
study incorporates field measurements and acoustic modelling methods to develop effective surface design treatments
that enhance the listening experience for remote students. Three significant acoustic parameters were assessed:
reverberation time (RT), speech transmission index (STI), and speech clarity (C50). The results indicate that surface
treatment on wall and ceiling areas have a substantial impact on the important acoustic parameters that emphasizes
on speech intelligibility. The findings from an in-depth investigation are beneficial for designers and educational
institutions in ensuring appropriate acoustic quality for hybrid learning settings. This setting concurrently enhances
students' learning experiences and performance. |
