<br/>   abstract  = {Loss of directional hearing is not only related to one-sided deafness, but
may also occur when using hearing aids or cochlear implants. Loss of directional
hearing does not only mean a significant reduction in quality of life. It becomes
a risk factor when it prevents, for example, reacting quickly to a potentially dangerous
situation in traffic. The aim of the project is to process auditory signals
so that they are suitable for visual sensory perception in order to help hearing impaired
people. Two prototypes are presented to graphically display sound. Despite
their limited functionality, they demonstrate the technical feasibility of such a device
consisting of commercially available components at a reasonable price. The
first prototype is based on a Raspberry Pi with a 3.2 inch display. The sound acquisition
is done with 4 lavalier microphones and USB sound cards. The second
prototype is also based on a Raspberry Pi. However, sound processing is moved to
an enhanced computing platform with an array of 8 SMD microphones, to ensure a
synchronous sound sampling, and a sound source location framework is used. Visualization
options based on the requirements of hearing impaired people are introduced.
Lessons learned are discussed and future work is presented.},
