Sound Listening Environments Inc. (SLE) was founded in 1997 to provide a new solution for chair noise control.

Students with hearing loss, autism and attention deficits are greatly affected by chair noise. With increasingly larger classroom sizes and more active settings, noise levels significantly increased.

Looking to resolve chair noise by providing easy access to a safe, ready-to-use solution. SLE launched it’s flagship product Hushh-ups® in 1997. For over 20 years Hushh-ups® has enhanced the acoustics in thousands of classrooms in North America and abroad.

The company founders remain committed to providing every student with the best listening environment for learning.
