Effective communication between teacher and student is the basis of successful education.

Recent studies show that in a noisy environment, students do not clearly hear the teachers, they have low concentration with reduced learning, motivation and interest. The consequences of a noisy environment can be due to a poor school performance.

The same problem afflicts school canteens where the high number of diners who talk is synonymous with high sound levels that generate a situation of discomfort towards both patrons and operators. Typically the average reverberation time of a classroom is 1.4 seconds, this means that the student perceives a dialogue in which the words overlap each other – national laws and UNI standards indicate optimal values ​​of the reverberation time for the classrooms and canteens.

Acoustic correction interventions are generally simple to implement but highly effective; often they are not taken into consideration because it is usual to imagine that expensive and complex interventions are necessary to solve this problem. The interventions are not very invasive and quick to implement but above all of unexpected effectiveness, which often leave the most suspicious incredulous.
