| dc.description.abstract | The quality of the learning environment in classrooms depends on various
factors. Building acoustics would be one of these factors. The two most
important issues as regards to this learning environment are excessive
background noise and reverberation. They both interfere with the ability of the
students to hear, listen, and understand what is spoken. It can lead to an overall
reduction in the level of learning. The research focused on reverberation time
or RT60. Standards presuppose that the acceptable range is 0.4 to 0.6
seconds. One second would be the maximum acceptable limit. The study was
conducted at the University of Mindanao, Matina Campus. This university is
known for its open admission. This open admission means that all types of
students are admitted with all the various levels of preparedness. It was
interesting to note that in the 2015 study of that university, the majority of its
new students are considered as not ready. The acoustical environment can
exacerbate the learning development of most of the students. This descriptive survey research used multi-stage sampling. The instrument used in
determining the RT60 was an Android App called Reverberation Time Pro,
which has been installed on the ASUS Z00LD smartphone. Only eleven percent
of classrooms are compliant. The features of these compliant classrooms
served as a guide for enhancement of the 89% that are not.
