Learning outcomes
The module aim is to introduce some characteristic physical concepts of the acoustics . It focuses, therefore, on the definition and properties of sounds, both in the time domain, both in the frequency domain and their transmission in free field and indoors. It also deepens acoustics psychophysics: the concept of loudness is developed, and the effects of noise on humans are clarified. In addition, the physical of ear is introduced, by means of the description of those physical phenomena that bind to the physiology of the ear. It is given a nod to the physics of phonation. Finally, the concept of bionic hearing is introduced and the main bionic subsidies and their sound processing mechanisms are described.
Program
INTRODUCTORY CONCEPTS: uniform circular motion, harmonic motion.
THE SOUND: the speed of propagation, the acoustic Ohm's law. Introduction of the concepts of sound pressure, sound intensity and sound power. Identification of links between sound intensity and power and between pressure and sound power. Introduction of the concept of sound density.
DEFINITION OF SOUND LEVELS. Logarithms and their properties. Definition of loudness.
THE SPREAD OF SOUND:
1- IN FREE FIELD
The presence of obstacles: introduction of the concepts of reflection, refraction and diffraction. Resonance definition. The outdoor sound propagation. Attenuation phenomena of sound level. Effects of directivity of the source.
Description of the Doppler effect.
2. INDOOR

ACOUSTIC PSYCHOPHYSICS: definition of loudness. Introduction of the physiological effects produced by noise.
EAR PHYSICs: introduction of concepts of physics and electronics on the pinna, the external ear canal, the middle ear and the inner ear. Definition of action potentials, with their properties.
PHYSICS OF SPEECH: description of a sounding board. Introduction of Bernoulli effect.
BIONIC HEARING: definition. Description of the main bionic subsidies and of their sound processing mechanisms for middle and inner ear. Hearing aids. Implantable hearing aids. Cochlear implants. Auditory brainstem implants. Experimental implants: inferior colliculus implants and PABI.
