At the end of this course, the students;

1. Relate amplitude, period, velocity and acceleration magnitudes of an object making simple harmonic motion with the vibration motion of the wave.
2. Show the characteristic properties of the sound waves (frequency, period, amplitude, wavelength, wave velocity, phase) on the graph (waveform or phase / amplitude spectrum).
3. Associates the concept of resonance with structures of ear anatomy.
4. Perform logarithmic sound pressure level (SPL) calculations using the concept of decibel.
5. Make mathematical calculations related to the resonator types formed by sound waves in different systems (closed-open, closed-closed, open-open ends).
6. Classify complex wave types as periodic (square, triangle, sawtooth, pulse train etc.) and aperiodic (transients).
7. Associate acoustic impedance and related concepts (resistance, mass reactance and flexibility reactance) with the anatomical structure of the ear, draw phasor diagrams.
8. Demonstrate the basic properties of sound filters by drawing on the graph for different filter types (high-pass, low-pass, band-pass, band-reject).
9. Explain amplitude, frequency and intermodulation distortions (distortion) occurring in sound waves.
10. Analyze parameters affecting the reverberation time in room acoustics (in environments with reflective, dispersive and absorbing surfaces of sound waves).
11. Establish relationship between physical quantities(sound pressure, frequency) and individuals' perception of these magnitudes (loudness, pitch).
12. Use Fletcher-Munson equal loudness curves to identify the perceived loudness level for different frequencies and different sound pressure levels (dB SPL).
13. Interpret the Mel scale which rates the pitch perception.
14. Compare the advantages and disadvantages of classical psychophysical methods used to find the absolute threshold of hearing.
15. Explain the basic concepts (hit, miss, false alarm, correct rejection) used in signal detection theory.
16. Explain the role of localization and lateralization skills in spatial and bilateral hearing.
