Course detail
Bioacoustics
FSI-RBKAcad. year: 2012/2013
Bioacoustics is dealing with human organs and the organs of the next living creature of which their function is connected to an using of acoustic waves summary of an acoustics using. Bioacoustics is dealing especially by the human voice generation and by the hearing perception. The source voice is generated by the vocal folds and is adapted when is going through the vocal tract. The source voice differs when it is generated in whisper or in aloud. The source voice is a cause of the formant excitation of individual vowels according the set up of the vocal tract. The formants are the natural frequencies of the vocal tract.
The other organ using the acoustic waves properties and vibro-acoustic systems anywise is a hearing system. The hearing apparatus catches the acoustic waves from surrounding environment and by means of complicated electrical-mechanical system them transformed into signals which are sent further into brain.

Assesment methods and criteria linked to learning outcomes
The claims for accreditation:
100 % attendance on the exercises. In case of the orderly excused absence is necessary to solve a alternate problem. Accreditation is carried out by means of the written test at the term end. The test consists of the three questions covered a very important areas of the acoustics subject. Participation on the exercises is compulsory. Head of exercises carry out continuous check of student’s presence , their activity and fundamental knowledge. A not excused presence in the exercise is a reason not to give the accreditation. Definite form of the fulfilment of these claims defines the head of exercises in the term begin.

Aims
In the BIOACOUSTICS subject the attention will be devoted to the both problems given above. The function both organs will be analysed theoretically, by the computer modeling by means of finite element method and further by the experiments.
