Environment is crucial to learning. The classroom where students stay about eight hours a day, at the average, for five days a week plays a crucial role in the learning process of students. The low level of performance of Philippine basic education students was once blamed to poor classroom acoustics (TIMMS, 1997). Being the site where knowledge is transferred through oral communication, the classroom’s capacity to ensure high quality communication between the teacher and students and between students is therefore very important. This is the reason why studies on classroom acoustics (Zannin et al., 2012) are getting numerous in recent years. Unfortunately, there seems a general disinterest for this topic in the Philippines.1 For example; classroom acoustics is not mentioned in the Building Code of the Philippines.
