A hearing aid may include a hearing aid housing. The hearing aid housing may include a first housing wall portion and a second housing wall portion. The first housing wall portion has a first flexibility, the second housing wall portion has a second flexibility and the first flexibility is different than the second flexibility.

A hearing aid has a housing, a signal-processing arrangement housed in the housing, an LED, an actuatable switching element arranged on the housing, and a battery. The LED is connected to a positive pole of the battery with its anode connector and to a first connector of the signal-processing arrangement with its cathode connector. The signal-processing arrangement is formed with a monitoring unit, which switches the first connector if there is a drop below a first threshold voltage such that the cathode connector can be connected to a negative pole of the battery.

An ear fitting piece for creating an ear impression and a method for creating an ear impression. In order to allow the creation of an ear impression at low cost, the ear fitting piece for creating an ear impression has a liquid, which has a first state in which it can be shaped and a second state in which it is solidified, a soft rubber sleeve, which encloses the liquid, and an activating device, which is designed to cause a change of state from the first state to the second state of the liquid. A further change of state from the second state to the first state of the liquid can be caused by heating.

Children should be prevented from easily being able to remove the ear hook of a hearing aid. It is for this reason that a hearing aid that is to be worn behind an ear has a housing, which houses signal-processing components, and an ear hook, which is detachably attached to the housing. During the attachment process, the ear hook is moved toward the housing in an axial direction. The ear hook and the housing are embodied such that, in order to attach the ear hook to the housing, there is at least one movement of the ear hook in a second direction and a movement of the ear hook in a third direction, which differs from the second direction. Both the second and the third direction differ from the first direction. It follows that a complicated movement pattern is required when the ear hook is disassembled from the housing.

It should be possible to balance microphones and hearing apparatus more reliably. To this end, provision is made for a method for checking a measuring situation, wherein at least two measurement points of a frequency response of the hearing apparatus are recorded. A check then establishes whether the at least two measurement points lie in a predetermined tolerance range above a threshold. If this is the case, an OK signal is output. Otherwise, if at least one of the measurement points lies outside the tolerance range, the position of the measurement point outside the tolerance range is ascertained and a fault signal is output depending on the ascertained position. It is therefore possible to establish, for example, whether a measuring chamber lacks proofness, a microphone is blocked or the microphone is completely malfunctioning.

A hearing aid has a housing, a battery compartment, and a locking mechanism for the battery compartment. A shaft which is arranged on the housing or the battery compartment, and a slide having a hole which forms a fit with the shaft, such that the slide can be moved on the shaft in order to lock and unlock the battery compartment in the housing. The hole has a circular cross section, and the shaft has a cross section which is not a circle, with rotational symmetry when rotated through 360°/n, where n is an integer greater than 1. A battery compartment for a hearing aid has a locking mechanism such as this. Because a cross section of said shaft is different from the cross section of the hole in the battery compartment, the shaft is connected to the hole in the battery compartment only at a number of points. This ensures that the slide is held adequately on the shaft even in the event of a production tolerance on the one hand, while, on the other hand, the slide can move on the shaft with little resistance. In a preferred embodiment the shaft is trilobular in cross-section.

The wind sensitivity of hearing aids is reduced. The noise level of at least two microphones is measured and to compared with one another. The microphones are controlled according to the comparison result. In one embodiment, the microphone having the lowest noise level is used as an omnidirectional microphone in a wind situation.

A hearing aid, in particular a behind-the-ear hearing aid, has a speaker for generating a sound signal, a connecting piece for emitting the sound signal, and a flexible sound tube for transporting the sound signal from the speaker to the connecting piece. The flexible sound tube is flexible at least in a longitudinal center section in a direction orthogonally to longitudinal direction. A method of assembling a hearing aid has the following steps: a longitudinal end of a flexible sound tube is fitted on/in a connecting piece or a speaker of the hearing aid; the flexible sound tube is bent toward the speaker or the connecting piece; and the second longitudinal end of the flexible sound tube is fitted on/in the speaker or on the connecting piece.

A hearing aid has a housing, in which an electrical heating device is disposed in the housing. Because of the electrical heating device, moisture that occurs inside of the housing can be removed from the housing in a simple way, irrespective of whether a watertight hearing aid or an open system is concerned.
