An attachment for a device for generating an air flow or dispensing a fluid, which attachment is designed to be at least partially introduced into an external auditory canal of a human or animal ear, the attachment including a connection piece for connecting the attachment to the device for generating an air flow, and a tongue-type guide vane for conducting air that flows out of the device for generating an air flow via the connection piece, the guide vane having a bottom.

An earpiece including an intra-auricular support, a projection element coupled thereto, and a flexible body disposed thereon and inside an external ear canal of an ear, and a moldable earpiece material moldable about the intra-auricular support to conform to the auricle of an ear and curable to provide a fixed configuration of the earpiece.

Systems and methods are provided for sealing an ear canal for retaining a solution in the ear canal. Adhesive earplugs are provided through which the solution can be delivered, and which, following delivery, retain the fluid in the ear canal. The systems and methods may also be useful for delivering an anesthetizing solution to the ear canal of a human patient and for maintaining the solution therein for use with an iontophoresis system for anesthetizing the tympanic membrane.

The present invention provides a customizable ear insert for fitting within a user's outer ear or ear canal or both and methods therefor. In accordance with an aspect of the present invention, there is provided a customizable ear insert having: a body formed of photocurable polymer, the body having a first shape configured for insertion into the outer ear canal of a user; a light source, the light source positioned adjacent the body, and wherein the body can be cured into a second shape by application of light generated by the light source, the second shape snugly conforming to the interior surface of the user's outer ear or ear canal or both.

A push-in earplug is provided. The push-in earplug comprises an elongate core comprising a core material. The push-in earplug also comprises an outer layer comprising a foam material, the outer layer covering at least a portion of an outer surface of the elongate core. The push-in earplug also comprises a channel extending through the elongate core from a first end of the elongate core to the second end of the elongate core.

An atmospheric pressure adjustment apparatus is disclosed. The atmospheric pressure adjustment apparatus comprises: a speaker; a microphone; an earplug of which a main body is made of an elastic material so as to seal the external auditory meatus when the earplug is worn on the ear of a user, and which comprises an atmospheric pressure adjustment part penetrating the main body; and atmospheric pressure adjustment device for adjusting the fluid volume of the atmospheric pressure adjustment part; and a processor for outputting a sound through the speaker when the earplug is worn, measuring the air pressure difference between the middle ear internal atmospheric pressure and the external auditory meatus atmospheric pressure of the user on the basis of the strength of a received echo when the echo of the sound reflected from the eardrum of the user is received through the microphone, and adjusting the atmospheric pressure difference by moving the atmospheric pressure adjustment device according to the measured atmospheric pressure difference.

An assessment system includes a sound data acquiring unit configured to acquire sound data collected by a sound insulation device, the sound insulation device being fitted into a wearer's ears; and an assessment unit configured to assess noise to which the wearer is exposed, based on the sound data acquired by the sound data acquiring unit and time information associated with the sound data.

An attachment for a device for generating an air flow or dispensing a fluid, which attachment is designed to be at least partially introduced into an external auditory canal of a human or animal ear, the attachment including a connection piece for connecting the attachment to the device for generating an air flow, and a tongue-type guide vane for conducting air that flows out of the device for generating an air flow via the connection piece, the guide vane having a bottom.

An earpiece including an intra-auricular support, a projection element coupled thereto, and a flexible body disposed thereon and inside an external ear canal of an ear, and a moldable earpiece material moldable about the intra-auricular support to conform to the auricle of an ear and curable to provide a fixed configuration of the earpiece.

A noise-cancelling earplug assembly is provided, having an ear piece for insertion into the ear canal and a housing removably attached to the ear piece. A hollow core is defined in the housing to receive a sound-selective sound barrier that contains at least one sound filtering element to attenuate sounds reaching the ear drum. An end cap is provided and is attachable to the housing to enclose the sound-selective sound barrier inside the housing. The sound selective sound barrier can be removed from the housing of the earplug and replaced with a different sound selective sound barrier with different sound attenuation characteristics.
