Leslie Tremulant Earmuffs

The Leslie Tone Cabinet(often heard with a Hammond organ) plays sound through a spinning horn, resulting in a tremulant effect. Both the amplitude and pitch are modulated together, and the sound seems to be spinning around you as it is projected toward—and reflects off—different parts of the room.

Wouldn’t it be nice if you could experience this type of sound modulation all the time? Well, now you can with Leslie Tremulant Earmuffs!

Each muff is equipped with a horn, similar to “ear trumpets” that hard-of-hearing people used to use, but smaller, and with a right-angle bend. The small end points toward your ear. The whole horn is driven by a motor, but the small end doesn’t move because it is at the axis of spin. The big end moves around sweeping out a vertical circle.

There are two speeds, slow and fast, which you can select from via a switch mounted on the head band. The motors for both ears are powered by two C cells, also mounted on the head band.

Stuck in a lecture or meeting with boring people droning on and on? Just flip on your Leslie Tremulant Earmuffs!
