F7ABBTA - Technical Audiology

Code Completion Credits Range Language
F7ABBTA KZ 2 1P+1L English
Enrollement in the course requires an successful completion of the following courses:
Anatomy and Physiology II. (F7ABBAF2)
Biological Signals (F7ABBBLS)
Department of Biomedical Technology

The aim of the course is to give students a basic overview of audiology, i.e. basic knowledge of biology,

medicine and technology in relation to normal and impaired hearing, and all this in an interrelated context with emphasis on

technical aspects. Motivation to work in clinical practice in audiology is also an integral part of this goal.


Course entry requirements:

These requirements are expressed as prerequisites and a detailed breakdown of the requirements is as follows:

- nervous system - organisation and function of the CNS, internal environment of the CNS (blood-brain barrier, cerebrospinal formation, transport and function), neuroglia, motor nervous system, spinal cord (structure, reflexes),

- nervous system - motor system, brainstem (structure, reflexes), cerebellum (structure, reflexes), basal ganglia (structure, reflexes), cerebral cortex (structure, rexlexes), physiology of movement control,

- sensory nervous system - receptors, skin sensation, movement and position perception, vision, hearing, taste, smell, pain, autonomic nervous system, brain stem, hypothalamus, peripheral compartments: sympathetic and parasympathetic,

- waves, types of waves, successive waves, interference, standing waves, sound,

- types of signals, basic signal operations, signal decomposition,

- harmonic analysis, Fourier transform for continuous and discrete signals, DFT, FFT,

- convolution,

- technical and biological systems, systems and their description, linear and non-linear system,

- external description of continuous and discrete linear system - differential/differential equations, transfer functions, frequency characteristics, distribution of zeros and poles, time characteristics,

- coupling of systems, feedback loops,

- Characteristics of basic biosignals EEG, ECG, EOG, EP, EMG, artefacts, origin, sources, diagnostic applications, frequency range and bands,

- Biological data acquisition and preprocessing, basic computer conversion chain, A/D converters, problems signal sampling and quantization, Nyquist theorem, conversion errors, signal conditioning, aliasing, filtering, trends, sensing options.

Output knowledge, skills, abilities and competences:

Students will acquire a basic understanding of acoustics, measurement and diagnosis of auditory functions, including technical principles. instrumentation and software, and hearing aids and replacements. The students will be able to orient themselves. They will be able to learn about these issues, learn about other areas of medical instrumentation and methods used in clinical practice, as well as motivated and ready to enter the field of audiology upon graduation and to add to this knowledge and advanced skills within the framework of the so-called certified course, which, according to Act 96/2004 Coll., allows for the acquisition of the so-called „certificate of audiology“. Special professional competence Technical audiologist after graduation, i.e. after obtaining the so-called professional competence Biomedical technician under the Act.


Conditions for the award of classified credit:

Only one absence from the exercise is allowed.

Successful completion of two tests focusing on lecture and exercise issues.

The number of questions in the test is 10 (ABC questions - only one correct answer).

All questions will be weighted equally and the student will receive 10 points for a correct answer. The minimum number of points for credit is 50 and the final classification

grade is determined by the ECTS scale (maximum 100 points).

Syllabus of lectures:

1. Introduction to the subject, motivation, relation to professions, examples of applications, summary review of basic anatomy and physiology of the auditory organ with a connection to physics

2. Acoustics (general, electrical, noise and hearing protection, acoustic measurements)

3. Measurement and diagnosis of hearing functions I. (objective audiometry, tympanometry and vestibular examination, OAE, subjective audiometry)

4. Measurement and diagnosis of auditory function II (design and operation of audiological instruments)

5. Measurement and diagnosis of auditory functions III (software solutions for audiological investigations)

6. hearing aids and hearing aid replacements I. (hearing aids, technical principles)

7. Hearing aids and replacements I. (cochlear implants, technical principles)

Syllabus of tutorials:

1. Acoustic measurements (selected issues)

2. Objective and subjective audiometry, tympanometry

3. OAE examinations (BERA, CERA, ...)

4. Audiological investigation using SW

5. Measurements with hearing aids

6. Cochlear implant measurements

7. Use of rehabilitation hearing aids in practice (these would be annotated videos showing how

the surgical part as well as the actual procedure of fitting the patient for different types of implants)
