Constructing a learning institution requires a lot of careful planning; imagine you are in a class where you cannot hear what the instructor is saying during a session. Classrooms constructed using acoustic plans is the key these days, due to the prevailing environmental issues like noise from the nearby blocks as well as schools taking on more students per class.

The purpose of good classroom acoustics is to give positive speech intelligibility for all students, prevent language interference, provide suitable background sound levels from all sources not in the room and equip sound decay times (reverberation time) that improve speech, allow effortless listening and reduce the noisiness. Achievement of these goals is easy.

Selecting a suitable site is the first task if you are dealing with a new build. Because of the requirement to achieve specific interior sound levels, a site with famous transportation or industrial sound sources raises the difficulty of achieving the design objective and the rate of the building. Many studies have revealed that all other social-economic limitations being equal, children in schools near major sound sources get lower on standardized tests. The most important job is to orient the buildings in the most noise responsive areas to reduce the influence of the main sound sources. In the case of existing building the use of natural sound barriers such as trees and water features could help reduce this peripheral noise.

Background noise is all the sound heard from unconnected sources that affect on concentration, communication, seclusion and productivity. Sounds from gyms, music rooms, playgrounds or sportsfields are some of the examples of background sound sources. Reverberation time (also known as sound crumble time) is an echo or a measure of the time it takes sound to die out. Reverberation can be measured on internal and external sound sources.

The next items to consider regard the internal properties of the building and how they affect speech privacy, speech interference and background reverberation. Speech privacy happens when a person in a neighboring space cannot hear adequate words to have an understanding of words spoken. Speech interference materializes when sound from other places prevents a person from understanding the phrases by a person to whom they are listening. It becomes essential to group your classroom assignments by sound requirement such as grouping maths and science classes which require high levels of privacy, or grouping language driven classes which require the low reverberation or speech interference, or grouping practical classes which tend to be noisier by nature.

It is advised to get professional advice on particular components of noise control such insulation and structural changes to recommend the most cost effective way to achieve speech privacy and avoid speech interference.
