Topics

  1. Overview of audio communication
  2. The physical basis for audio
    • Acoustic variables: Sound pressure, velocity, intensity, impedance
    • Sound fields
    • Sound conversion: Microphones and loudspeakers
    • Sound storage: Record, CD, SACD, DVD-Audio, MP3
  3. Audiotory physiology
    • Peripheral hearing system
    • Otoacoustic emissions (OAEs)
    • Central hearing system
  4. Psychoacoustics
    • Methods
    • Auditory field, masking
    • Critical bands
    • Loudness
    • Pitch and pitch strength
    • Just noticable differences
    • Sharpness
    • Fluctuation strength, roughness
    • Binaural hearing: binaural cues, sound localization
  5. Applications: Selection of current research topics from
    • Audiology and hearing devices
    • Room acoustics
    • Speech evaluation
    • Audio technology
    • Sound quality design

Excercise Course
