Acoustics2

**__A classroom for 40 students__**



Acoustic comfort is the set of acoustic conditions that allow us to perform our activities properly and normally no risk of discomfort. Its three basic components are: privacy, concentrations and intelligibility.

The privacy measures the degree above which a conversation can not be heard by others. It is measured by the signal to noise ratio that expresses the difference between the level of the speaking voice and background noise. The concentration is disturbed by intrusive noise. Intelligibility is the assessment of the understanding of communication within a given space.

Acoustic comfort is essential in education, it is essential for learning that students will keep the attention focus and concentration which are necessary for low noise and good intelligibility conducive to study and listen to the teacher.

In the study centers is aggravating the disparity of activities taking place simultaneously in them, which forces compatible classrooms, libraries, hallways or playgrounds that can become very noisy spaces. Make this compatibility is not problematic for the more sensitive areas like the classroom of a certain number of students, we can only get it through proper design, good venues, good insulation between the various venues and conditioning of spaces such that noise is reduced and favors the intelligibility.

In each room there is to balance the absorption and sound attenuation to achieve the required comfort. This way you can achieve the three basic components of acoustic comfort mentioned at the beginning.



Another way to improve is with the installation of acoustic ceilings. The acoustic performance of a roof are defined through: a sound absorption coefficient and attenuation coefficient.
