Directional microphones need to be aligned to a horizontal axis in order to have the best directivity. However, microphones which are positioned horizontally are visible behind the ear. Up to now, the decision for directivity or for discreteness is an unsatisfying trade-off. In addition, the microphones are susceptible to environmental stress such as dirt, moisture and other. Up to now, the microphones cannot be exchanged or even reconditioned. Microphones covers are used instead in order to protect the microphones. Furthermore, the current wireless technologies require more space of the hearing aid housing which leads to big hearing aid.
