Beginning of the course: 28 September 2018
ATTENTION! The course begins with a demonstrative visit to Casa del Suono, Piazzale Salvo D'acquisto - 1 - Parma, at 14.30. After a brief introduction of the course, the students will have the possibility to experiment with the advanced recording and playback audio and video systems installed in Casa del Suono. These are some of the topics of the course....
Thecourse ofAppliedAcousticsis an introductory course to a scientific andtechnologicalfieldundergoing a very rapid development, which offers great employmentopportunities,andwhich involves disciplines apparently very different:architecture,structural engineering, physiology, psychology, statistics,physics,electronics, vibration mechanics, fluid dynamics, digital signalprocessing, telecommunications, measurements, hygiene of the workplace,music, musicology, virtual reality.
Obviouslyinapost-graduate course of 6 CFUs we can only provide the methodological basis of Applied Acoustics whichmust then befurther studied in more advanced courses, such as courses for Competent Technicians in EnvironmentalAcoustics (typically 3-6 months)orMaster Courses (1 year) available at some Italian universities,or evendedicatedpost-graduatedegrees (2 years, for example thepost-graduate(advanced)degree inMusical Acoustics ofPolitecnico di Milano).
Becauseof itsmultidisciplinaryand transversal nature, the Course of Applied Acousticsisattended bystudents from various degree programs (almost all branchesofEngineering, butalso students of Architecture and Physics).
Forstudentsof allbranches of engineering this is a key course,itis practicallythe only opportunity to see (or, rather, hear)thetechniqueslearned in previous courses, in which the purelytheoreticalfoundations of modern advanced mathematical methods are taught.When the "numbers" are transformed in sound, abstruse and difficult mathematicalproceduresquicklybecome veryclear and immediate,andthepossibilities offered by sound editing systems on the PC,usedextensivelyboth during lectures and duringlaboratoryexercises, make it possible to listen immediately(usuallyin realtime) to the "effects" of filters or otherdevices(compressors, gates, convolvers, denoising, etc.).
Given the scientific interests of the teacher, the course covers both the noise-related topics common to all branches of engineering , and the morespecific themesrelative to the acoustics of theatres and cinemas, audio productionin music and television / film, musical instruments, high fidelityrecording and Stereo(1D), Surround (2D) andthree-dimensional (3D, VR, AR) systems.
Many students donot understand the physical meaning of "differentiation" and "integration" operators applied to a function. Math teacherstend to give"graphical" explanations , such as "thederivative is the slope of a curve" or "theintegral is the area under a curve." These explanationsare useless for those who are devoid of the capacity of visualisationneeded to transform these concepts into images.
Inacoustics, theoperations of differentiation or integration modify the spectrum of asound. Inparticular, differentiation boosts high frequencies(increases the soundlevel of 6dB/octave). On thecontrary, integration boosts lowfrequencies. Here's anexample, which allowsto "listen" todifferentiation and integration applied to a recording of the humanvoice:
The method of examination is quite standard: a written test, based on exercises, followed by an oral final question, mostly theoretical. The oral question follows the written exam, but is always done the same day. This method is unchanged in the last 9 years.
These students will still have the possibility to improve their starting score, by making the written exam the same day as the final oral question, with the safety that, if the written exam results in a score lower than the score of the in-class test, the latter will still be considered as the starting score for the oral questions. In practice you can only get a better score, not worst; hence there is no risk attempting to improve your score with the written exam.
The written exam is made typically of 3 or 4 exercises, with numerical solution, similar to those of the in-class tests. It lasts one hour, the correction is immediate, and after this the students perform immediately the final oral question.
The final oral question is simple and short, an typically takes no more than 5 minutes. It causes a small variation (positive and negative) of the score already obtained with the written exam, which remains the most relevant part of the evaluationprocedure. Typically the final oral question gives a maximum variation of +/- 3 points, which only exceptionally can go up to +/5 points.
Thewritten exercisesare to be completed in an one-hour time limit, typically starting at9.15, after the nominative call procedure is completed. After a few minutes for the correction of the exercises, the oralexaminations start (typically around 10.30).
Duringthe writtenexercises it is possible to employ all of the above material, includingnotes and/or textbooks; instead, during the final oral question, thestudent is not allowed to consult his/her notes or books, but he/shecan still employ charts and tables - so it is advisable to keep themseparate from the notes.
Exception to this rule is allowed only for students with certifiedLearning Disabilities (LD, DSA in Italian), who are invited to contactthe teacher before the exam, possibly by Email or in person, instead of passing through the LD Office "Le Eliche".
Forthe writtenexercises, each student is given two pieces of paper: the examinationform, which includes the problems and there are spaces for writing theresults, and one 4-faces "protocol" foil, where the student shouldwrite clearly the passages required for getting the solutions. Bothsheets must carry, since the beginning of the exam, name, surname, matricula and signature of each student. It is forbidden to write on anything elsethan the "protocol" sheet: if one is not enough, additional "protocol"sheets can be asked to the examiner. All the "protocol" sheets must begiven back together with the examination form.
Foroptimal trainingto the exercises, it is strongly discouraged to"study" thesolution of already-solved problems. The only way to be trainedcorrectly is by attempting to solve problems without any preliminaryknowledge of the correct solution. For this, it can be useful todownload the text of the problems which were employed in past years,which can be downloaded here:
It is alwaysmandatory to satisfactorily answerto at least one oralquestion,typically on theoretical topics, even for students who passed the written exercises or the in class tests with maximum score.
The evaluation of the oral examination, which usually is positive, insome cases can provide a NEGATIVE score, reducing the score obtained inthe written part. Normally a range of +/-3 points is available. Only in very exceptional cases thisrange can be expanded to +/- 5 points, based on the sole evaluation ofthe examiner. And, independently from the sum of the scores, ifthe oral examination is judged unsatisfactory, the student can alwaysbe rejected.
