One aspect of the present subject matter includes a method of using a first hearing assistance device in a first ear of a wearer to communicate with a second hearing assistance device in a second ear of the wearer using wireless communication, and determining whether quality of the communication between the devices has fallen below a programmable threshold such that communication can be improved by relaying the communication using an external intermediary device such as a smart phone. One method of determining the quality is to monitor a number of retransmissions that are used to maintain communication between the left and right devices.

A hearing assistance system comprises an input unit for providing electric input sound signals u.sub.i, each representing sound signals U.sub.i from a multitude n.sub.u of sound sources S.sub.i, an electroencephalography (EEG) system for recording activity of the auditory system of the user's brain and providing a multitude n.sub.y of EEG signals y.sub.j, and a source selection processing unit receiving said electric input sound signals u.sub.i and said EEG signals y.sub.j, and in dependence thereof configured to provide a source selection signal Ŝ.sub.x indicative of the sound source S.sub.x that the user currently pays attention to using a selective algorithm that determines a sparse model to select the most relevant EEG electrodes and time intervals based on minimizing a cost function measuring the correlation between the individual sound sources and the EEG signals, and to determine the source selection signal Ŝ.sub.x based on the cost functions obtained for said multitude of sound sources.

According to an embodiment, a hearing aid is disclosed. The hearing aid includes a first functional unit and a second functional unit. The second functional unit is configured to removably couple with the first functional unit. The coupling provides at least a mechanical connection between the first functional unit and the second functional unit. The first functional unit includes a moveable element that is configured to move between a first position and a second position. In the first position, the moveable element is contained entirely within the first functional unit. In the second position, a part of the moveable element is configured to protrude out of the first functional unit. The second functional unit includes a recess configured to receive the part of the moveable element that protrudes out of the first functional unit such that the first functional unit and the second functional unit are immovably locked with respect to each other in response to the moveable element is received in the recess.

Methods and devices for measuring vibration of an implanted driven vibrating elongate body coupled to a bone of the middle ear, for example using an accelerometer coupled to the vibrating body. The measured vibration can be taken during implantation and long again after implantation to check for possible decoupling, disease, or additionally impeded vibratory driving of the middle ear bone. An accelerometer signal can be converted to a displacement value and used to check for an under impeded or over impeded vibratory body. An implanted device can be used to periodically check the vibration of the vibratory body. Methods and devices can be used in conjunction with implanted devices which receive vibratory signals from a middle ear bone and use the signals to drive a disarticulated middle ear bone closer to the ear drum.
