Sound propagation in fluids; speech, hearing, noise, architectural acoustics, loudspeakers, microphones, transducers, underwater sound transmission.7. Course objectives/student learning outcomes/program outcomes Course objectives1) To introduce the principles of underwater and airborne acoustics 2) To provide a practical working knowledge of underwater acoustics through problem solving, laboratory experiments and computer projects 3) To provide the fundamental knowledge needed for designing acoustic systems. 4) To provide practice using the computer as an everyday engineering tool. Student learning outcomes & relationship to ABET a-k objectivesAn ability to apply the knowledge of mathematics for formulation and analysis of acoustics problems. A thorough knowledge of the basic properties of sound propagation and mechanisms of sound generation An ability to calculate sound levels. A ability to write simple computer codes 8. Course evaluation method Ethics Test 5% Two exams during class (10% ea) 20% Homework & Quizzes 25% Laboratories & computer task (8% ea) 20% Comprehensive Final Exam 30% Note: The minimum grade required to pass the course is C. 9. Course grading scale Grading Scale: 95 and above: A, 90-95: A-, 85-90: B+, 80-85: B, 75-80 : B-, 70-75: C+, 65-70: C, 60-65: C-, 55-60: D+, 50-55: D, 45-50: D-, 45 and below: F. The final grade for the course will be the numerical average of grades assigned for all work in each of the categories listed above weighted according to the percentages shown. The instructor reserves the right, in exceptional cases, to raise or lower the final numerically averaged course grade by 2.5% in cases where the instructor does not believe that the average is representative of the student's performance in the class. Normally, the student will receive the numerically-averaged letter grade for the course. 10. Policy on makeup tests, late work, and incompletes Students are expected to attend all classes and complete laboratory assignments. Any exam, laboratory or quiz missed will be averaged as a zero. Make-ups will not be given except in the case of illness, or with the prior permission of the instructor. An Incomplete, or an I, will only be given out if a student, while carrying a passing average, becomes ill and is unable to complete the course on time. An I will not be given out to a student failing the course 11. Special course requirements 12. Classroom etiquette policy University policy requires that in order to enhance and maintain a productive atmosphere for education, personal communication devices, such as cellular phones and laptops, are to be disabled in class sessions. 13. Disability policy statement In compliance with the Americans with Disabilities Act (ADA), students who require special accommodations due to a disability to properly execute coursework must register with the Office for Students with Disabilities (OSD) located in Boca Raton campus, SU 133 (561) 297-3880 and follow all OSD procedures. 14. Honor code policy Students at Դɼ are expected to maintain the highest ethical standards. Academic dishonesty is considered a serious breach of these ethical standards, because it interferes with the university mission to provide a high quality education in which no student enjoys unfair advantage over any other. Academic dishonesty is also destructive of the university community, which is grounded in a system of mutual trust and place high value on personal integrity and individual responsibility. Harsh penalties are associated with academic dishonesty.
