CODE 65468 ACADEMIC YEAR 2025/2026 CREDITS 1 cfu anno 1 LOGOPEDIA 9282 (L/SNT2) - GENOVA SCIENTIFIC DISCIPLINARY SECTOR FIS/07 LANGUAGE Italian TEACHING LOCATION GENOVA SEMESTER 2° Semester MODULES Questo insegnamento è un modulo di: PHYSIOLOGY AND BIOCHEMISTRY TEACHING MATERIALS AULAWEB AIMS AND CONTENT AIMS AND LEARNING OUTCOMES At the end of the course, the student should: know the basics of acoustics; know the laws of acoustics that specifically intervene in the mechanisms of language; know the physical phenomenology underlying hearing; be familiar with the technical units of measurement used to characterise sounds. TEACHING METHODS The course is conducted in the second semester of the first year by means of lectures (10 hours) using mainly screen presentations and exercises. SYLLABUS/CONTENT Physical quantities involved in sound. Acoustic pressure. Velocity of sound. Characteristic impedance of a medium. Sound intensity. Sine plane waves. Wavelength, frequency. Fourier techniques. Principle of superposition. The ear and Fourier analysis. Transmission and reflection coefficients in intensity. Classification of sounds according to frequency. Decibels. SIL and SPL scales. Frequency scale in the audible. The human vocal apparatus. Use of apps on mobile phones to check frequencies and formants by calculating Fourier transforms. RECOMMENDED READING/BIBLIOGRAPHY The texts (in pdf format) of the presentations projected in class are made available online. Supporting text: D. Scannicchio - E. Giroletti - Elements of Biomedical Physics - EdiSES (Naples).

Class schedule ACOUSTICS EXAMS EXAM DESCRIPTION Verification of learning takes place both in written form by means of open-ended questions and the performance of simple numerical exercises and in a discussion of the papers. ASSESSMENT METHODS The student will have to demonstrate that he/she has learnt the notions explained to him/her in the course and has therefore achieved an acceptable attainment of the envisaged learning objectives (see detailed learning objectives). FURTHER INFORMATION The examination cannot be taken if the propaedeuticities laid down in the Study Course Regulations are not met. Since these are integrated course examinations, failure to pass a single discipline entails repeating the entire examination.
