HEARING AIDS II
LEARNING OUTCOMES OF THE COURSE UNIT
The course aims to enable students to know and understand basic information on the anatomo-physiology of the auditory and vestibular apparatus and on the theoretical and prescriptive basis of the acoustic amplification, also in order to allow students to use these knowledge and understanding in identifying the patient's problems related to the condition of a person suffering from a disease and to prepare an appropriate care plan
COURSE CONTENTS SUMMARY
The lessons cover topics such as the outer, middle and inner ear anatomy, the temporal bone and facial nerve anatomy, the liminal tonal audiometry, the supraliminal audiometry and the impedance; Fundamentals of the theory of measurements. Unit of measure - Champions - Accuracy and resolution of the measurement - Calibration of instruments, Measurements in the acoustic field.

ASSESSMENT METHODS AND CRITERIA
The achievement of the goals of the course is verified by an oral exam.
Answering questions about the contents of the course, the student will demonstrate whether he/she has achieved the goals of knowledge and understanding of the contents and the ability to apply the acquired knowledge.
Class lessons: the program themes will be discussed with the aid of slides. The proposed topics will be the subject of collective discussion and study on the basis of ideas and any questions raised during the lessons themselves.
