Objectives
Programme
Lectures (each in 2 hours extent):
1. lecture: Basics of aoustics from the point of view of audio engineering: sound pressure, sound pressure level, sound waves.
2. lecture: Reflections in enclosed spaces: reverberation time formulae by Sabine and Eyring, energy decay curve, critical radius, standing waves, assurance of adequate absorbance.
3. lecture: Psychoacoustics I: the mechanism of our hearing, subjective loudness, definition of phom and sone, critical bands.
4. lecture: Psychoacoustics II: spectral and temporal masking effects and their usage in psychoacoustic encodings, transient detection.
5. lecture: Sound source localisation (based on intensity and phase), stereophonic directional hearing (phantom source localisation), surround sound: Quadro, Dolby Stereo, -Surround (Pro Logic), -Digital, Haas effect (i.e. source localisation in rooms, its use in sound reinforcement tasks).
6. lecture: Elements of sound radiation systems and their properties (regular, horn, cluster), subwoofers, positioning of loudspeakers near to walls/corners.
7. lecture: Strongly directed sound radiation, interpretation of directivity. Electronically controlled speech columns: beam-width, -elevation.
8. lecture: Line-array systems, difficulties of sound reinforcements in large-scale concerts (side radiation, positioning of subwoofers). Power properties of amplifiers: sinusoidal/musical/rms power, peak to rms ratio, optimisation for PA (=Public Addressed) applications, digital amplifier.
9. lecture: PA vs. HiFi loudspeakers (efficiency, dynamics, sound quality). Active vs. passive loudspeakers (efficiency, frequency range, sound quality, weight, price). Studio monitors vs. HiFi loudspeakers.
10. lecture: Microphones in audio engineering: dynamical, condenser, gouping of microphones based on their usage. Important parameters of microphones from the point of view of audio engineering: frequency range, directivity pattern.
11. lecture: Analogue signal transmission: symmetric-assimetric transmission, phantom powering, signal levels (microphone, electrical instruments, line level), dB references: dBV, dBm, dBu, earth-loop, DI-Box, transmission of digital audio signals: AES/EBU, SPDIF, ADAT, MADI.
12. lecture: Sound-system technique: microphones, mixing consoles, effects, loudspeakers, monitoring, recording. Channel and master section of mixing consoles, synchronisation of digital equipment, automatisation.
13. lecture: Selected topics of mobile sound reinforcement: wireless audio signal transmission, powering of loudspeakers and other sound processing devices.
+1 lecture: the sum of the 3 “small clausures” each lasting 30 minutes (equally distributed along the semester)
Laboratory (each lasting 4 hours):
1. Sound studio practice: signal transmission
2. Seting up and measuring sound radiation systems
3. Programming of sound effects (in Matlab)

The goal of this lecture is to teach participants those knowledge, which is expected to be known, whom call themselves as Audio Engineer in Hungary. Special emphasis is on sound reinforcement questions, because the innocence of practicing sound engineers is in that area the greatest. The man goal of this course is to make students, who knowledge in the field of electrical engineering, able to master at high level sound reinforcement and other audio engineering tasks.

General rules
Requirements:
a. During the semester: 3 “small clausures” (each lasting less than 30 minutes), from which at least 2 have to surpasse a note of 2 to receive signature.
b. In exam time: written exam with oral correction possibility
c. Computation of final note: 80% E + 10% sC/a + 10% sC/b
(rounded towards the nearest note), where E means note of the exam, sC/a and sC/b mean the 2 best notes fo the small clausures.
c. Proposed note: by absolving all three small clausures, if their mean achieves or surpasses the note 4, then by acceptance of this note
d. Pre exam: no
Additional possibilities:
The small clausures cannot be recovered
