Abstract:
A sound attenuator that allows a user to adjust the amount of attenuation in a variable, continuous fashion or in a discrete controlled fashion from zero attenuation to maximum attenuation without removing the device from the ear. The ear attenuator includes a housing having a passageway, the passageway allowing for sound to pass through the housing and a variable control, the variable control able to control the size of the passageway through the housing and the amount of attenuating material located within the passageway through the housing.
