Technical aspects of hearing aids, 7.5 credits

Admission to the course requires that the student has completed at least 45 credits from semester 1-2, with passing grades in Part 1 and 2 from the course Hearing assessment 1.

The general aims of the course are that the student should acquire basic knowledge about the design of hearing aids and function as a preparation for future courses in hearing rehabilitation.

The expected learning outcomes of the course
After completing the course, the student should be able to

• account for and explain non-linear and linear signal processing electroacoustic systems and be able to distinguish the systems from one another both theoretically and through interpretation of measurements
• describe and account for the components in different hearing aid styles and explain how these interact in an electroacoustic system
• describe and account for the technical function of different assistive listening devices
• independently be able to carry out measurements of the electroacoustic properties of hearing aids by means of measurements in measuring tool (coupler) and be able to describe and interpret the results of these measurements.

The following parts are included:

Lectures, group work, laboratory sessions and demonstrations. Group work, laboratory sessions and demonstrations are compulsory.

In case of absence from compulsory part, the student is responsible for contacting the course director for complementary assignment.

The course director assesses how absence from compulsory education elements can be substituted. Before the student has participated in the compulsory parts or has replaced compulsory education, in accordance to the instructions of the course director, the final study results cannot be reported.
Absence from a compulsory education element may lead to that the student can not recover the occasion until next time the course is given.

Part 1: Technical aspects of hearing aids, 6 HE credits
Written examination

Part 2: Electroacoustic measurements, 1.5 HE credits
Written laboratory report i group

For a Pass grade in the course, attendance and active participation in compulsory parts are also required. Students who do not pass a regular examination are entitled to re-sit the examination on five more occasions. Each time the course is offered, one regular examination and two additional examinations are given.If the student has failed six examinations/tests, no additional examination is given.
Each occasion the student participates in the same test counts as an examination. Submission of a blank exam paper is regarded as an examination. In case a student is registered for an examination but does not attend, this is not regarded as an examination.

Examination can take place according to an earlier literature list during a time of one year after the date when a renewal of the literature list has been made. Examination will be provided during a time of two years after a possible close-down of the course.

Assessment criteria for examination, specific instructions for certain tasks and timetable with specification of compulsory parts and list of responsible teachers may be found on Pingpong on the first day of the course.

Course evaluation will be carried out according to the guidelines that are established by the Board of Higher Education. The course evaluation is carried out both through a written course evaluation at the end of the course and through an oral course forum, at least once in connection with course, where students can state his opinions.
