Master Craftsman Preparatory Classes

The Academy of Hearing-aid Acoustics offers various classes to prepare fort eh national Master Craftsman exam, targeting Hearing-Aid Acoustic Journeyman or Master Craftsmen of other professions as well as engineers who wish to work in the field of hearing-aid acoustics.

The classes impart all the knowledge and skills, which are legally required (Official Federal Gazette) for the Master Craftsman Exam. The students have the opportunity to practice with the equipment out of class hours and on the weekends.

The Master Craftsman Exams of the examining boards Rheinhessen-Mainz and Halle are held in the premises of the Academy of Hearing-Aid Acoustics with the equipment the students are used to work with. A smooth running of the exams is guaranteed thanks to years of experience.

1.Fulltime Class („Master Craftsman Course of Studies“) Part I-IV
This course extends over an 11-month period at the Academy of Hearing-Aid Acoustics. All parts required for the Master Craftsman Exam are offered as full-time training courses. If the student has already completed part III and IV or wants to do these parts separately, he /she can still pick this full-time course, i.e. it is possible to do certain parts separately. This way, these students will have additional time for individual studying.

We have also integrated the recommended preparation of the European Diploma/Certificate Hearing-Aid Acoustician in this course. In addition to the regular teaching units, the student selects a specific subject from the field of hearing acoustics, does research and writes a final thesis. He then also has to present his thesis in a colloquium and explain it to a committee of experts.

2.Part-time Class in Lübeck on the weekends („MVWK North“) Part I and II
This course is designed for all those who cannot attend a fulltime class, allowing a combination of both, working in a company while preparing for the Master Craftsman Exam on the weekend. In Lübeck we offer 8 weekend modules with 24 teaching units, each from Thursday to Saturday and another 3-week period with 40 teaching units. The entire class up to the Master Craftsman Exam extends over one year. The exam will be taken in the summer.

3.Part-time/Weekend class in Würzburg / Lübeck („MVWK South“) Part I and II / NEW
This is another course for students who cannot attend a fulltime class. It also allows combining the regular work within the company with studies preparing for the Master Craftsman Exam. In Würzburg we offer 8 weekends modules with 24 teaching units – Monday to Saturday and afterwards, two weeks in Lübeck with a total of 60 teaching units. The entire class up to the Master Craftsman Exam extends over a one-year period; the exam will be taken in the fall/winter.

Bachelor Course of Studies Hearing Acoustics in Lübeck

In 1999 the first German Hearing Acoustic Diploma course of studies already set the benchmark for the professional qualification of a trade. Developed and implemented in co-operation of the Academy of Hearing-aid Acoustics with the University of Applied Sciences, it was changed into a Hearing Acoustic Bachelor course of studies in the winter term 2004/3005.

The fitting of hearing systems in order to guarantee an optimal rehabilitation of hearing-impaired people is a comprehensive process, which does not only require specific technical knowledge, as for example on digital signal processing, but also considerable medical-audiological and especially psychosocial skills. The Bachelor course of studies Hearing Acoustic in Lübeck embraces the entire spectrum of hearing acoustics and is directed towards interdisciplinary work. It helps close the gap between the technical vocational training to become a hearing-aid acoustician and the theoretical studies at university.

The course of studies is geared towards young people who want to work on a high professional level, use their practical knowledge and take over managerial functions in the field of hearing-aid acoustics. The course of studies combines the vocational training as hearing-aid acoustician with a course of studies at the University of Applied sciences and consequently is very practice-oriented. Content-wise it is based on the three following key points:

  • Technical as well as mathematical-scientific field
  • Hearing acoustic and medical-audiological field
  • Business administration and economics

The interdisciplinary orientation of the Lübeck course of study prepares its students in the best possible way for the challenges they are confronted with in their future fields of activity audiology and hearing acoustics, e.g. in one of the following roles:

  • Head of a hearing-acoustic specialist company
  • Specialist in an audiological center
  • Audiological consultant
  • Specialist in the audiological-technical industry, especially companies producing hearing-systems.

The course of study is very practice oriented. Students work on individual projects in the field of hearing acoustics, focusing on current topics from their professional practice and will also to a 10 week internship either in the industry, a clinic and hearing-acoustic audiological company or a similar institution. Furthermore there we will organize regular field trips, which will give students an additional insight into the various fields of activity in this profession. During the field trips and the internship period they will gather valuable experience and establish contacts. By choosing specific course that will deepen their knowledge in a certain area, students can start to focus on certain topics, which are of personal interest to them and are useful for their future careers. This way, students have a chance to develop a specific profile not only in the technical, medical-audiological but also in the business administrative field.

The Lübeck Hearing-Acoustic course of studies is organized according to international standards and rates he performance of students according to the European Credit System (ECTS), which facilitates the recognition of credits in other European countries. During the internship period or while preparing the final thesis, valuable experience abroad can be gathered. A very notable characteristic of this course of study is that the theoretical part of the Master Craftsman Exam Hearing-Aid Acoustic will be recognized and is compatible with the requirements of the European Diploma/Certificate „Hearing-Aid Acoustician“ of the Association Européenne des Audioprothésistes (A.E.A.).

Implant Specialists

Implant specialists are responsible for the optimal care of hearing-impaired persons, who have received a hearing implant. Due to the technical integration of regular and implantable hearing systems, it is in the best interest of hearing impaired people to receive a comprehensive and interdisciplinary after-care. Therefore it is of vital importance to integrate a hearing-aid acoustician in the process of fitting hearing implants.

The professional training of a hearing-aid acoustician includes many aspects of audiology and hearing system technology. A hearing-aid acoustician will offer in depth counseling on rehabilitation methods, chooses suitable hearing systems plus accessories, fits these systems according to the individual and audiological particularities of the hearing-impaired and carries out post-fitting hearing measurements. Consequently hearing-aid acousticians are predestined to be involved in the entire inter-disciplinary process of providing hearing-impaired with implantable hearing systems.

The advanced training of a hearing-aid acoustician to become implant specialist further promotes the integration of the hearing-aid acoustician in the process of implant fitting and aftercare. Only a co-operation of ENT clinics, ENT doctors, health physicists and audiologists, pedagogic institutions, manufacturers and health insurances will guarantee a comprehensive treatment of the patient.

Upon completion of this advanced training course, participants will have acquired the theoretical knowledge and basic practical skills to:

  • Carry out an indication evaluation and do a pre-selection according to audiological criteria
  • Conduct an educational counseling on the various kinds of hearing implants
  • Ensure inter-disciplinary co-operation of ENT clinics, doctors, health physicists, audiologists, pedagogic institutions and manufacturers
  • Offer technical support
  • Work out an individual aftercare concept, which takes the audiological and technical parameters and be part of the implementation of this concept
  • Diagnosing and fixing problems
  • Ensure the hearing-impaired patient is well taken care of in the entire process of dispensing hearing systems with invasive and non-invasive techniques.

This course does not include the expert course on the fitting of cochlear implants, which is offered individually by each company. The fitting of other implants (Baha, MOI, Retro X) is possible upon completion of the advanced training.



As national center of excellence for the continued education and advanced training of all hearing-aid acousticians, the Academy of Hearing-Aid Acoustics actively supports the quality and training initiative of the Federal Guild of Hearing-Aid Acousticians, public corporation, by offering expert seminars and inter-branch seminars all over Germany. You will receive more detailed information in time.
