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...
