Case Study
Neueinstellung eines Fachpraktikers für Zerspanungsmechanik


The medium-sized company manufactures turned parts according to customer order in contract manufacturing.

Disability and functional restriction of the employee:

The man is extremely hard of hearing and only very limited acoustic information, such. B. speech and signals to perceive. For him, therefore, audible information must be strengthened so that they can be perceived acoustically by the man again - without also increasing noise, so as not to worsen the hearing even further.

Education and job:

The employee completed an apprenticeship as a professional mechanic for machining mechanics in a vocational training center (BBW). At his current employer, he was recruited for the turning shop as Zerspaner.

Workplace and work duties:

The specialist works in the production of CNC lathes for the production of turned parts and was incorporated at the beginning of his activity accordingly. The programs are mainly written in the work preparation and then transferred to the machines. It may happen that corrections have yet to be made by the specialist on the respective machine or on the respective program. In addition to equipping the machines with material and tools, he is also responsible for setting up the machine, checking and checking the quality and maintenance as well as cleaning. Chips and the turned workpieces are transported via conveyors to containers. The use of machines and conveyors in the production hall creates noise and / or noise, which makes it difficult for the employee to perceive important acoustic information (speech, warning signals, etc.). The employee therefore received noise-approved hearing aids with customized hearing programs and earmolds to enhance the speech and attenuation of the noise generated by the machines and conveyors. This enables communication in the hall and at work with supervisors and colleagues and ensures the acoustic perception of warning signals for accident prevention.

Assistive devices used:

hearing aids

Keywords and Further Information

Funding and participation:

The hearing aids were funded by the statutory health insurance or health insurance to compensate for the disability with a fixed amount. Since the professional practitioner also has to perceive speech and special acoustic signals in the noise area at his workstation and at the same time has to be protected from noise, it was not possible to provide a hearing aid with disabilities at a fixed amount. The additional demand for suitable hearing aids was therefore promoted by the Employment Agency as part of the new hiring, whereby the advice was provided by their Technical Advisory Service. The Employment Agency also promoted initial training at the BBW and the employer as an integration subsidy as a monthly wage subsidy, as the practitioner is severely disabled, was unemployed and required more training than usual. The consultation, measurements and adjustment of the hearing aids was carried out by a hearing aid acoustician.
