Abstract

University is an important stage of learning for students, so it is vital that higher education spaces are acoustically accessible to all and are places that promote equity and inclusion. The aim of this study was to measure the unoccupied noise levels and reverberation times of all of the classrooms in a typical Australian university to assess acoustic accessibility with a view to planning for a more accessible campus. A total of 166 classrooms were measured and categorised into good, ok, and poor classrooms according to the Macquarie University (MQU) Design Guidelines Review Performance Standards. Regarding unoccupied noise levels, 52% of classrooms were within the recommended < 35 dBA limit. Regarding reverberation times, 65% of classrooms were within the recommended 0.4–0.6 s limit. Finally, 40% of classrooms met both the noise level and reverberation time limit. The plans at the university to incorporate these findings to make the campus more acoustically accessible are discussed, as well as future research avenues so that all students and teachers can flourish.

实现无声校园：澳大利亚一所大学的声学条件案例研究

大学是学生学习的一个重要阶段，因此高等教育场所的声学无障碍性以及促进平等和包容至关重要。这项研究的目的是测量澳大利亚一所典型大学所有教室的闲置噪音水平和混响时间，以评估声学无障碍程度，从而规划出一个更无障碍的校园。共测量了 166 间教室，并根据麦考瑞大学（MQU）设计指南审查性能标准将教室分为良好、尚可和较差三类。在闲置噪音水平方面，52% 的教室在建议的 35 dBA 限值范围内。在混响时间方面，65% 的教室在建议的 0.4-0.6 秒范围内。最后，40% 的教室同时符合噪声级和混响时间的限制。本文讨论了该大学为使校园在声学方面更加无障碍而纳入这些研究结果的计划，以及未来的研究途径，以便所有学生和教师都能茁壮成长。
