Shush Instruments is a small instrument maker based in Sheffield, England, focused on designing quiet tin whistles intended for practice and low-volume playing environments. The company uses a proprietary blade geometry — a rounded 'Sh' blade — along with an acoustic dampening compound to reduce output volume and soften overtones while preserving playable tone.

The product line centers on a handful of whistle models: the Shush Classic in High D, the Shush Classic in High C, the Shush Bb, and the Shush PRO in D, which the maker positions as the flagship model after further refinement of the original Classic design. Whistles are offered in brass or nickel finishes and are hand-finished and individually checked before leaving the workshop. The original Classic series is built on a Feádog body modified with Shush's own blade and internal treatment.

Shush's niche is narrow and specific — reducing the decibel output of a tin whistle without killing its musicality — and the brand is discussed primarily in the traditional Irish and folk whistle community, where practice volume is a persistent concern. Reviews in the tin whistle press have noted the instruments' unusually muted output compared to standard production whistles.
