Subject guarantor:

Zdeněk OTČENÁŠEK

Name of lecturer(s):

Zdeněk OTČENÁŠEK

Learning outcomes of the course unit:

This course broadens basic knowledge in the perception of a music signal. Students are acquainted with the psycho-acoustic linked to the concept of sound, psycho-acoustic dimensions, their physiological traverses and the relationships among subjective perception properties of sound and objective properties of sound signals.

Mode of study:

1 hour per week.

Prerequisites and co-requisites:

Basic knowledge of physiologic and music acoustics.

Course contents:

Acoustics: sound, mass point oscillation, sound spread, acoustic field

Acoustic line from sound source to hearing perception, sounce of music sound and sound signal

Objective properties of sound signals: Time course, incidential ,continual, periodic signal, transient signal, signal analysis in time domain (periodicity, correlation)

Sound time development: Transient events, post-oscillation state, modular and quasi-periodic signals, Composition of comprehensive signals, signal analysis (band filters, FFT, DFT, wavelettes), anti-aliasing, spectra time development, weighting, average spectra, static and dynamic signal concept (tone, noise).

Subjective properties of sound signals: the listening process and hearing perception, subjective dimensions

Listening principles: internal ear, neurogram, music sound distinguising mechanism, non-linear distortion in listening

Neurogram: perception of a simple tone, critical band width, perception of two simple tones, echo, first order events, aural and combination tones

Second order events, reverb of out-of-tune consonance, perception of fundamental tone, residual tone

Psycho-acoustics: sound hearing, hearing tests, presentation of sound stimuli, psycho-acoustic measurement

Sound assessment: Verbal and non-verbal methods, assessor compliance, objectivization of results

Basic psyco-acoustic dimensions (volume, pitch, duration, color), sound quality, relations of objective and subjective dimensions.
