Even the best hearing implants often improve hearing insufficiently. The cause for this often is the lack of a way to focus on sounds from specific directions, with too much noise as a result. Bees are experts in this directional hearing. Martijn Agterberg will examine the hearing organs of honeybees and bumblebees, in order to learn and provide information to improve hearing aids for humans. Recently, he received an Open Mind grant for this, worth 50.000 euro.
