Proudly Canadian owned and operated since 1997, Sound Listening Environments Inc. (SLE) was founded to provide a new solution for chair noise control.

Chair noise disrupts students, particularly those with autism, hearing loss and attention deficit disorders. With larger classrooms and higher activity levels, this issue significantly increased.

Looking to resolve chair noise with a simple, safe, ready-to-use solution, SLE launched it’s flagship product Hushh-ups® in 1997. For over 20 years Hushh-ups® has has enhanced acoustics in thousands of classrooms across North America and globally.

We are committed to helping every student achieve the best listening experience for focused learning.
