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:

Sound color: multidimensionality, acoustic and psycho-acoustic concepts

Objective color causality: spectral (frequency structure of a sound signal and its internal interaction), time (changes in periodicity and irregularity)

Perceptual space in relation to a 3D depiction of a music signal: dynamics level (time package, percussive, non-percussive, tremolo), melodic (frequency, instant frequency, harmonics, vibrato), harmonics (basic classification of music signals).

Presentation of the sound spectra: Schumann law of tone color and its application, interval and formant concepts

Sources of music sound: measuring vibrations of chordophones, string oscillations, resonator properties; measuring aerophones, oscillation mechanisms, vibrations of sound column, measuring vibrations of idiophone and membranophone, stick oscillations and plates and membranes

Tuning musical instruments, system overview, tuning measurements

Voice: measuring the human vocal system, vocal chords, vocal tract, formants (vowels, consonants): Dynamic properties (whisper, accent): Melody and understandability of words

Singing voice: vocal field measurement, development and division according to range, singing voice intonation and techique, breathing measurements

Sound in space: Binaural hearing, time-space perception of sound, sound color as a binaural phenomenon

Sound properties of musical instruments (dynamic, performance), influence of sound on spatial acoustics

Organs: pipe organs, tone color of lip and reed pipes, organ sound construction, diapozon registers

Electronic organs, static and dynamic synthesis (linear, non-linear), summary and differential methods, Furier and Non-Furier, modulational, form, comprehensive signal filtration;

Physical and mathematic modelling.
