EN2100 Sound Perception 7.5 credits

Can sounds be distorted in such a way that the distortion is not noticeable? How can we understand speech in noise that is louder than the speech? Why do we hear sound sources "out there" and not inside the head? How can we objectively measure subjective sound impressions? Can a hearing loss be compensated by external signal processing? The course in Sound Perception gives you tools to answer this kind of questions.

Content and learning outcomes

Course contents

The course is about human hearing and gives basic knowledge about design requirements for technical sound presentation and sound transmission systems, with regard for human auditory perception.

Intended learning outcomes

The participants shall after the course

  • understand in some detail how human hearing works
  • be able to assess how sound perception affects the usefulness of technical systems for sound reproduction
  • be able to apply basic psychoacoustic testing methods to measure hearing or to evaluate the sound quality of reproducing systems
  • be able to use computational models for estimating subjective properties of sounds and systems, such as loudness and speech intelligibility
  • have some knowledge of the consequences of hearing impairments and limitations in technical aids for the hearing impaired.

Grading scale

A, B, C, D, E, FX, F


  • INL1 - Individual Assignment, 1.0 credits, grading scale: P, F
  • LAB1 - Laboratory Work, 0.5 credits, grading scale: P, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

Other requirements for final grade

Exam 6 p (A-F). Homework assignment 1 p (P/F). Lab exercise 0.5 p (P/F).

Ethical approach

  • All members of a group are responsible for the group's work.
  • In any assessment, every student shall honestly disclose any help received and sources used.
  • In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
