Course Objectives The aim of this course is to learn basic psychoacoustic and acoustic concepts, as well as psychoacoustic and acoustic measurement principles.
Course Learning Outcomes The students who succeeded in this course;
  • Relates the amplitude, period, velocity and acceleration of an object in simple harmonic motion to the vibration motion of the wave.
  • Defines the characteristics of sound waves (frequency, period, amplitude, wavelength, wave speed, phase) and shows these characteristics on a graph (waveform or phase/amplitude spectrum).
  • Defines the concept of resonance and associates it with ear anatomy.
  • Makes logarithmic sound pressure level (SPL) calculations using the concept of decibel.
  • Makes mathematical calculations about the types of resonators formed by sound waves in different systems (closed-open, closed-closed, open-open ends).
  • Describe the function of Fourier analysis in the analysis of complex waves and classify complex wave types as periodic (square, triangle, sawtooth, pulse train etc.) and aperiodic (transients).
  • Draws phasor diagrams by associating acoustic impedance and related concepts (resistance, mass reactance and elasticity reactance) with the anatomical structure of the ear and explains which direction the system becomes dominant at low and high frequencies by mathematical inference.
  • Demonstrates the basic properties of audio filters for different filter types (high-pass, low-pass, band-pass, band-reject) by plotting them on a graph.
  • Explains amplitude, frequency and intermodulation distortion in sound waves.
  • Analyzes the parameters affecting the reverberation time in room acoustics (in environments with surfaces that reflect, disperse and absorb sound waves).
  • Establishes a relationship between physical quantities (sound pressure, wave frequency) and individuals' perception of these quantities (loudness, pitch).
  • It uses the Fletcher-Munson equal loudness curve to determine the perceived loudness level for different frequencies and different sound pressure levels (dB SPL).
  • Interprets the Mel scale grading the perception of treble.
  • Compare the advantages and disadvantages of classical psychophysical methods used to find absolute hearing thresholds.
  • Explain the basic concepts used in signal detection theory (hit, miss, false alarm, correct rejection).
  • Explain the role of localization and lateralization skills in spatial and bilateral hearing.
Course Content Evaluation of the positive and negative effects of sound hearing and echo control; technical measures to be taken during application and use.
