The man has a hearing impairment with a mutual tinnitus or annoying ear noises, a back disease and a knee joint damage. Hearing impairment with additional tinnitus is the cause of an occupational accident. To improve hearing he uses hearing aids with Tinnitusmasker, which superimposed the annoying noise of the ears by a second noise. The GdB
(degree of disability) is 100.,
Education and job:
The man has completed a teacher training with subsequent legal clerkship for the elementary school. He works or teaches 21 lessons on a part-time basis in the subjects sports and expertise.
To reduce the burden, he was allowed to reduce working hours by five to 21 lessons.
Workplace and work duties:
The teacher teaches mainly in a specially equipped classroom with carpeting, curtains and sound-absorbing materials on the walls to improve the room acoustics. Nevertheless, despite the hearing aids and the improved room acoustics, there are communication problems with the pupils. Especially in the first and second grade, the students speak softly and shyly and he has to constantly ask to understand the contents. Even at official meetings (eg conferences and meetings) in other rooms, the teacher can only follow the verbal communication to a limited extent. For this reason, an FM system (directional microphones, transmitter and receiver) was used, which can be used in combination with the new digital hearing aids - the old hearing aids were not suitable for this. In the classrooms and at meetings, the teacher places wireless directional microphones with zoom function on the tables. The microphones align themselves with the incoming voice signal and can thus record and zoom in on voice signals from different directions. About the transmitter in the microphone then the spoken, z. As the students, recorded and transmitted to the two recipients. The very small receivers are connected to the hearing aids via an audio shoe or an interface and transmit the speech directly to the hearing aids without any background noise. The other by the hearing aids perceived incident or noise can be filtered using various programs of hearing aids that can be changed via a remote control. For example, the remote can also be used to adjust the volume of the hearing aids.
In conversations with just a few people, the teacher only needs one microphone, which he can place on the table in the middle of the group or attach to his clothing.
Due to the number of students, the teacher often develops a disturbing and burdensome noise level. With the help of a noise lamp this is measured and visually displayed. If it is too loud or if the noise level is too high, the traffic light turns red and an additional acoustic signal appears. Often, students are unaware that they are too loud. The sound of the lights should now clarify this to them and exhort them to be calmer.
Assistive devices used:
