ABSTRACT |
It has been known that the effects of acoustics parameters of the room on auditory perception were diverse and even critical in some
population groups. Public regulation on classroom acoustics has emerged as one of the concerned issues in educating children and the
hearing impaired. The purpose of this study was to review the effects of acoustic parameters, such as reverberation time, acoustic insulation,
and acoustic absorption, on speech perception in classroom. An exemplary regulation suggested from ANSI (S12.60, 2002) and
related assessment tools were analyzed as well with special reference to adapting appropriate guidelines to domestic environments.
In conclusion, it seemed now imperative that the related authority should establish effective acoustic requirements and guidelines for
schools since ample data showed that the young children with hearing problem were prone to be at risk of learning opportunities. The
reviewed parameters were dominant physical variables of speech intelligibility in classroom acoustics and this analysis might help to
resolve issues on implementing acoustic regulation on classroom acoustics in the future. |
