Abstract
A hearing protection earmuff may be configured to dampen vibrations at an interface. Generally, the hearing protection earmuff may comprise two ear cups, a headband attached to and connecting the ear cups, one or more sensors, a processor, an electroacoustic shock absorber, and an electromagnetic controller. Typically, the electromagnetic controller may be associated with an electroacoustic shock absorber and may be configured to control the dampening of the electroacoustic shock absorber. The dampening of the electroacoustic shock absorber may occur as a smart fluid changes viscosity in response to a signal received from the electromagnetic controller. In some embodiments, the clamping force between the headband and the ear cup may be varied by the electroacoustic shock absorber to minimize the vibrational impact on the user's ears. In some embodiments, the electroacoustic shock absorber may control the compressibility of the seal cushion located on each ear cup.
