Knowledge
Students are expected to acquire:
knowledge about the physics of sound (origin, characteristics, propagation) in its
interactions with humans and the environment (refraction, reflection, standing waves, acoustic impedance);
knowledge on principles of ear physiology and psycho acoustics;
knowledge on the classification of hearing damages, on audiometric techniques like acumetry, tonal liminal audiometry, auditory masking and speech audiometry;
knowledge on the operation of audiometric equipments.
Assessment criteria of knowledge
In the written exam (1 hour), the student must demonstrate his/her knowledge of the course material.

Syllabus
Definition of sound, sound wave propagation, wave equation, acoustic impedance, Helmholtz resonator. Sound pressure, power and intensity, sound field. Sound physical features and human perception, Weber-Fechner law, decibel, sound level composition, audiogram, sound weighting curves and filters. Wave propagation: reflection, refraction, beats, Huygens' principle. Standing waves, resonance, sound tubes. Acoustic physics and physiology: sound localization, auditory canal and resonance, middle ear and impedance matching, inner ear and mechanical-electrical transduction. Complex sounds and Fourier Analysis: amplitude and phase spectrum, stationary constraint of the signal, resolution in time and frequency.
