Custom Sonic Valves provide a uniquely intelligent solution to protecting you hearing whilst shooting. Because of the sporadic nature of dangerous noise encountered when shooting, Sonic Valves protect you only when you need it most, allowing you to hear normally when there is no gun being fired.

The passive valves react upon impulse from sound waves and shutdown momentarily when the gun fires but still allow you to hear normally otherwise. They are not electronic and the valve barrels can be removed for easy cleaning of the moulds.

Because sonic valves allow you to hear under normal circumstances without any impedance, they are ideal for sportsmen, police firearms officers and army personnel.

Please note: as these sonic valve protectors are custom fit products, impressions need to be taken of your ears - when you call to order this product a free impression appointment will be made for you at your local Boots hearingcare centre.
