In order to understand speech in noisy classrooms, children require a better signal-to-noise ratio (SNR). Roger SoundField significantly boosts a young student’s chance for academic success by providing an improved acoustic environment for listening and learning.

Offering best-ever speech-in-noise improvements for normal hearing children of up to 28% at 65 dBA of noise and 50% at 70 dBA over no soundfield, Roger SoundField is in a class of its own.

Noisy classrooms can result in teachers suffering from vocal strain – leading to poor vocal health in the long term and increased costs due to teacher absences. A survey in the UK by the Royal National Institute for Deaf People revealed that 59% of schools reported teaching days being lost due to vocal strain. 

A recent study in Brazil showed that using Roger SoundField in a classroom, for just one period of the school day, was enough to improve dry throat symptoms, voice quality, fatigue while talking and vocal strain in teachers.

​The risk of longer-term vocal health problems is also lower and because teachers need to repeat themselves less often, there’s more time in class to cover lesson material.

Students being able to hear and respond to instructions better has not only shown improvements in academic performances but in-class discipline is also easier to maintain.

​Schools perform better financially too, thanks to reduced teacher absenteeism due to voice loss – and reduced replacement-teacher costs.
