Embodiment Construction

[0060] The detailed description given below in conjunction with the accompanying drawings serves as a description of many different configurations. The detailed description includes specific details to provide a thorough understanding of a number of different concepts. However, it is obvious to those skilled in the art that these concepts can be implemented without these specific details. Several aspects of the device and method are described by a number of different blocks, functional units, modules, elements, steps, processes, etc. (collectively referred to as "elements").

[0061] Figure 1A with Figure 1B A device for sensing vibration generated by a bone conduction hearing aid according to an embodiment of the present invention is shown. The device 100 is shown schematically, where the device includes a proximal end 105. The proximal end includes a proximal peripheral portion 105', which includes a material suitable for contacting the skin of the user of the bone conducti...

Abstract

According to an embodiment, an apparatus for sensing vibrations produced by a bone conduction hearing aid is disclosed. The apparatus includes a proximal end, a distal end and a side surface. The proximal end comprising a proximal periphery comprising a material adapted to, during a measurement, contact a skin of a user of the bone conduction device and to enclose a skin area within the proximal periphery. The distal end comprising a measurement microphone adapted to, during the measurement, receive an acoustic signal in dependence of vibrations produced at the skin area, the vibrations being representative of skull vibrations produced within the user by the bone conduction hearing aid in response to a sound signal. The side surface, in combination with the proximal periphery and the distal end, adapted to define an acoustic signal transmission cavity that allows transmission of the acoustic signal from the skin area to the measurement microphone during the measurement.

Description

Technical field [0001] The present invention relates to measuring equipment and methods. Specifically, the present invention relates to equipment configured to detect vibrations generated by bone conduction hearing devices and to facilitate the calibration and / or operation of bone conduction hearing devices. Background technique [0002] Air conduction (AC) hearing aids are commonly used for the rehabilitation of hearing impaired patients. However, for certain ear canal and middle ear disorders such as congenital malformations, chronic ear infections, purulent ears and ear canal eczema, etc., AC hearing aids cannot be used or they are not enough to solve the problem. In these situations, traditional bone conduction (BC) hearing aids can be used as an alternative. Bone conduction is a mechanism that transmits vibrations through the skull (rather than through the eardrum and middle ear like normal air conduction hearing). [0003] Sound is transformed into nerve impulses at the in...
