Communication Acoustics

Course Description

The course will offer knowledge on the following topics: Hearing process and hearing physiology. Sound source localization methods, Precedence effect, interaural time and intensity differences. Sound source localization precision. Binaural hearing and head related transfer functions. Masking and perceptual coding. Psychoacoustical parameters. Roughness, sharpness, fluctuation strength. Loudness and pitch perception. Sound quality. Listening tests. Sound evaluation methods, measurements of sound perception. Auditory scene analysis. Speech intelligibility. Influence of spaces on hearing sensation. Auralization. Auditory virtual environments.

Learning Outcomes

  1. Analyze functional elements of the hearing process
  2. Breakdown of methods used by the hearing system for sound source localization and identification
  3. Create a system for binaural recording and binaural sound synthesis
  4. Evaluate the sound quality based on psychoacoustic parameters
  5. Prepare speech intelligibility measurements in a communication system
  6. Use of different methods for speech transmission quality evaluation in a channel
  7. Assemble elements of sound auralisation in virtual reality system

Forms of Teaching

Lectures

The theory of communication acoustics and psychoacoustics is explained. These phenomena are also explained through demonstrations, where applicable.

Seminars and workshops

Work on a selected topic from the field covered in the course through a joint project.

Independent assignments

Individual work on a selected topic from the field covered in the course

Laboratory

The students will evaluate psychoacoustic parameters of hearing and communication acoustics through exercises in small groups.
