Abstract:
Systems, apparatus, and methods for filtering acoustic energy include a first conduit substantially aligned with a longitudinal axis and defining a first opening for receiving incident acoustic energy from the environment. A cavity in fluid communication with the first conduit selectively amplifies and/or dampens the acoustic energy based on an associated resonance frequency. A moving element disposed in the cavity may be displaced relative to the cavity in a direction substantially aligned with the longitudinal axis and in an amount related to a sound pressure level of acoustic energy in the cavity. A second conduit substantially aligned with the longitudinal axis and in fluid communication with the cavity selectively attenuates acoustic energy from the cavity based on the sound pressure level by receiving at least some of the acoustic energy from the cavity and/or the moving element when it is displaced from the cavity.

Claim (Index 21):
A method for protecting hearing of a listener in an environment, the method comprising:\n inserting at least a portion of a device in a human ear canal, the device having an outer shape defining a first opening for receiving incident acoustic energy from the environment and a second opening positioned opposite to the first opening for transmitting filtered acoustic energy into the ear canal, the device having a longitudinal axis extending from the first opening to the second opening; receiving incident acoustic energy from the environment via the first opening in the device, a first conduit extending inward from the first opening; selectively amplifying and/or dampening the acoustic energy via a cavity in fluid communication with the first conduit based on a resonance frequency of the cavity, the cavity further comprising a mesh element disposed in a plane substantially normal to the longitudinal axis, the mesh element dividing the cavity into a proximal compartment for receiving the acoustic energy from the first conduit and a distal compartment; selectively attenuating, based on a sound pressure level of acoustic energy in the cavity, acoustic energy from the cavity via liquid disposed in the distal compartment and a second conduit in fluid communication with the distal compartment and extending outward to the second opening, the liquid displaceable relative to the device in a direction substantially aligned with the longitudinal axis and in an amount related to the sound pressure level of the acoustic energy in the cavity, the second conduit receiving at least a portion of at least one of the acoustic energy from the cavity and, when displaced from the distal compartment, the liquid; and transmitting the filtered acoustic energy via the second opening of the second conduit positioned opposite to the first opening along the longitudinal axis.
