Single-Course English 10 ECTS

Acoustic Communication

Overall Course Objectives

This course covers a broad variety of topics related to fundamental elements involved in acoustic communication: hearing (anatomy, physiology), hearing loss, perception of sound (psychoacoustics), speech production and intelligibility. Through lectures, participants will learn about these topics as well as psychoacoustic measurement methods and diagnostic techniques. Working in groups, the students apply these methods in laboratory exercises and present their results in written reports.

Learning Objectives

  • describe the structure of the ear and explain the function of the various components.
  • sketch the hearing threshold in a free field (dB SPL-Frequency) and interpret the course of the curve.
  • compare classical and adaptive psychometric methods, explain essential concepts in signal detection theory, and explain a psychometric function.
  • explain the concept of loudness and loudness level and describe Stevens’ power law.
  • explain the concept of masking (simultaneous-, forward-, backward-) and it’s relation to the function of the inner ear.
  • explain how speech is produced and describe the physical properties of the speech signal.
  • define the concept of speech intelligibility, explain how different factors influence intelligibility, and discuss methods for measuring and predicting speech intelligibility (AI, SII, STI).
  • describe the principles of sound localization and sketch results of localization measurements.
  • discuss different diagnostic techniques, classify different hearing loss types by means of an audiogram, and explain the implication of a hearing loss for the perception of sound.
  • write an exercise report that is understandable for next year’s students.

Course Content

The anatomy and physiology of the ear. Psychophysical principles and psychoacoustic measuring methods. Psychoacoustics (hearing threshold, loudness, masking, frequency selectivity etc).
