Methods and apparatus are provided for protecting the external ear from the elements, heat, cold, wind, rain and/or snow. In some embodiments, an ear protector comprises a conforming anchor with an opening through which the external ear may be passed. The ear protector further comprises an insulating outer covering that, in combination with the anchor, forms the ear protector with a chamber positioned between the outer covering and the anchor. During use, the chamber is configured to receive the external ear, with the anchor's opening conformably positioned in proximity to at least a portion of the ear's root. The perimeter of the conforming anchor's opening resiliently deforms during passage of the external ear through the opening and into the chamber, and then conforms to the geometry of at least a portion of the ear root in order to securely and comfortably maintain the ear protector in position over the external ear without additional external support. The conforming anchor preferably is fabricated from a closed cell foamed elastomer.

A method and system for conveniently producing a hearing device for a consumer that can involve manufacture of a hearing aid or other hearing device from a mobile site or a site the is near and convenient for the consumer. Techniques similar to those used in dentistry can be used to take impressions of the ear canal, produce a mold, and finally produce a custom fitted hearing device. Alternatively, a light curable resin can be placed into the outer ear canal and partially or totally hardened with a light source in-situ to take the shape of the ear canal. The device can be removed and finished. Hearing aid electronics can be mounted into cavities created in the device to form a final hearing aid or other hearing device. By supplying hearing aids or other devices on-site, the consumer pays less, and can receive a final fitted hearing device in around an hour.

One (13) of the pads engages the Cymba Concha, and a second pad (14) engages the area between the Tragus and the Antitragus. A third support pad may engage the rear wall of the Concha.

A tympanic membrane drain tube is formed so that it is possible to freely trim a tip end of a hollow tube which has a large diameter at a rear end on the external ear side and tapers toward a front end, whereby the drain tube can be inserted into a stoma formed in the tympanic membrane under clear vision, and can naturally shed.

The present invention relates to a cap (11) intended for use as hearing protection and adapted to enclosed the external ear of a user, characterized by at least one vibration-damping weight element (18, 38a-b) of the cap (11), which weight element is arranged so as to at least partly block an audio mode of vibration that would have existed in the cap in the absence of said weight element (18, 38a-b). The invention also relates to a method of producing such a cap, and use of the same.

A device is worn on the head that covers the outer ear. The device comprises one or more materials that exotherm upon activation, so that the device generates heat. The generated heat is contained within the ear cap or covering for the outer ear, and the heat is communicated with the ear canal. The heat reduces pain associated with infection or pressure changes, and assists in equalizing pressure within the ear.

A system dries water droplets within a person's outer and inner ear. The presence of the droplets is typically caused by swimming, showering, bathing, and other activities associated with water sports such as diving, water polo and the like. A hair dryer blows warm air at a distance into a handheld drying apparatus. One or more diffusion chambers containing a plurality of apertures deliver warm air from the hair dryer into the outer ear. An integral central tubular element forming part of the diffusion chamber delivers warm air from the hair dryer into the inner canal. The diffusion chamber has a handle to help position the central tubular element within the inner ear canal. The distance between the hair dryer and the handheld drying apparatus may be varied to select a comfortable warmth level and warm air velocity.

The invention discloses a manufacturing method for an acellular dermal matrix tympanic membrane and an external ear tissue repair material. The method comprises the following steps of A, selecting mammal body or human body dermis tissue; B, determining three adjacent layers of dermis tissue alpha layer structures similar to the structure of tympanic membrane tissue in the dermis tissue structure by comparing the dermis tissue with the tympanic membrane tissue structure; C, removing the other layers except for the dermis tissue alpha layer structures in the dermis tissue structure to obtain a dermis tissue alpha layer preliminary material. According to the specificity of the dermis characteristics and the tympanic membrane tissue structure for development and improvement, and the tympanic membrane repair material similar to the human body tympanic membrane structure and the tissue characteristics is obtained. On the basis that the tissue integrity repair is completed, the tympanic membrane function is basically repaired, and the clinic effect is greatly improved; the raw material sources of the material for manufacturing the acellular dermal matrix tympanic membrane and the external ear tissue repair material are broadened, and the cost for manufacturing the repair material is lowered.

The invention discloses a biomechanical research, modeling, verification and application of human ear for railway vehicles to provide thoughts and basis for the design and evaluation of noise comfort of the railway transit equipment. The verification method includes establishing a plane wave source in the external ear as the acoustic excitation and applying pure timbre of a series of different frequency and sound pressure level in the external ear. Based on the acoustic modal analysis of external ear and the domain modal analysis, the ear finite element model and the sound sensitive band of the fluid domain finite element model are obtained and the matching between the sound sensitive band and the actual sensitive band of the human auditory system is compared. And based on the acoustic solid coupling method and the mode superposition method, the tympanic membrane and the acoustic response of stapes footplate are respectively obtained, and compared with the ANSI curve. The reliability of the ear finite element model and the fluid domain finite element model are determined by combining the results of the above two comparisons.
