A hearing device including a housing, a receiver within the housing, and a contaminant guard having a guard sound port and one or both of an outer contaminant receptacle, which is located outward of the guard sound port and that extends around the guard sound port, and an inner contaminant receptacle, which that is located on the central axis of the guard sound port and operably connected to a location outward of the guard sound port.

Systems and methods for detecting and diagnosing causes of subpar performance of a hearing device are provided for a user. The hearing device may include a housing, a receiver and a sound processor configured to send signals to the receiver. The receiver may be configured to output audio signals from the signals sent by the sound processor. A base unit may include a main body having a cradle formed therein. The cradle may be configured to receive the hearing device therein. A base unit microphone interfaces with the cradle and may be configured to receive output audio signals from the receiver when the hearing device is received in the cradle. The base unit microphone and the receiver remain in open communication with a space exterior of the base unit when the hearing device has been received in the cradle. A processor associated with the system may be configured to compare signal energy levels of test audio signals produced by the base unit microphone, in response to the audio signals received from the receiver, with signal energy levels of reference audio signals, and to indicate a blockage of the receiver has occurred when a difference between the signal energy levels of test audio signals and the signal energy levels of reference audio signals exceeds a threshold difference.

An exemplary hearing device may comprise a housing configured to be worn at an ear of a user and an absorbing member positioned on the housing and configured to absorb a biofluid secreted by outer ear tissue of the user while the housing is worn by the user. The hearing device may further comprise an electrode assembly positioned with respect to the absorbing member such that the electrode assembly is in fluidic contact with the biofluid when the biofluid is absorbed by the absorbing member.

A hearing device and related methods are disclosed. The hearing device comprises a housing comprising a wall, a microphone inlet comprising a through-going opening, a microphone arranged within the housing for receiving audio via the microphone inlet, a first filter device comprising a first filter material, the first filter device being arranged at the microphone, and a second filter device substantially having the shape of a torus or a hollow cylinder and comprising a second filter material, the second filter device being arranged at the wall, wherein the first filter device is arranged between the microphone and the second filter device, and wherein the through-going opening comprises an outer recess in an outer surface of the wall, wherein the second filter device is arranged in the outer recess.

A replaceable filter member for a hearing aid device is disclosed. The filter member comprising an unit with a housing configured to be inserted into the ear canal of a user of the hearing aid device. The filter member is configured to prevent ear wax from entering an opening in the housing. The filter member is a one-piece body that is configured to cover several openings in the unit while being attached to the unit.

A hearing device seal module in accordance with at least one of the present inventions includes a tubular seal carrier defining a lumen configured to receive a hearing device core and including a connector region and a resilient seal support region formed from resilient material, a seal carrier support connected to the seal carrier connector region of the tubular seal carrier, including a support tube defining a longitudinal axis and a lumen configured to permit movement of the hearing device core and a tool along the longitudinal axis, and having an open state and a closed state.

An ear-canal earpiece having an electroacoustic sound transducer, a sound guide unit having a first and a second end for guiding the sound from the electroacoustic sound transducer to an ear of a user and at least one portion. The ear canal earpiece has a canal having a first end open towards the ear canal and a second outwardly open end. A diaphragm is provided in the canal and extends over the entire cross-section of the canal.

A transducer protection system for the protection of at least one transducer opening in a housing of a hearing device, including a support and a plurality of fibers each fixed at one end to the support and free to move on the other end.

A hearing aid fitting system (400) adapted for providing sound samples illustrating the impact on sound quality from a hearing aid system defect and a method of providing such sound samples. The invention also relates to a hearing aid system and computer program code capable of carrying out such a method of providing sound samples illustrating the impact on sound quality from a hearing aid system defect and methods of operating and fitting hearing aid systems.
