    摘要： The present disclosure generally relates to devices for covering an ear, and more particularly to such devices that are self-attaching and used for sound optimization, such as noise reduction. More specifically, the present disclosure is directed to hearing protection muffs that comprise a sound attenuating cap, a self-attachment member for engaging the sound attenuating cap to the ear of a user, and optionally a sealing member. Advantageously, the muffs of the present disclosure have good sound attenuating properties and do not require a band or other external attachment device to secure the muffs to the ear.

    摘要： Self-fitting device for location in ear canal, including first end portion joined with second end portion. First end portion including first resilient bladder and first chamber of fluid and second end portion including second resilient bladder and second chamber of fluid. The bladders are in communication via the chambers. First bladder is deformable between at-rest position to in-ear position to insertion position such that first bladder has first cross-sectional area in at-rest position, second cross-sectional area in in-ear position and third cross-sectional area in insertion position. First cross-sectional area is greater than second cross-sectional area which is greater than third cross-sectional area. Second bladder is deformable to cause first bladder to be deformed from at-rest position to insertion position before device is located in ear canal.
