Student Wellness resources - List of community, local and private resources, relating to mental health and wellness.

Counselling Services - Counselling Services can help you make the most of your university experience.They offer free professional, confidential, inclusive support to currently registered UVic students. A note to remind you to take care of yourself. Do your best to maintain a healthy lifestyle this semester by eating well, exercising, getting enough sleep and taking some time to relax. This will help you achieve your goals and cope with stress. All of us benefit from support during times of struggle. You are not alone.

Health Services - University Health Services (UHS) provides a full service primary health clinic for students, and coordinates healthy student and campus initiatives. We encourage students to use UHS as their primary point of health care while at UVic. We are located at the Petersen Health Centre.

Centre for Accessible Learning - The CAL staff are available by appointment to assess specific needs, provide referrals and arrange appropriate accommodations . The sooner you let us know your needs the quicker we can assist you in achieving your learning goals in this course. 

Elders' Voices - The Office of Indigenous Academic and Community Engagement (IACE) has the privilege of assembling a group of Elders from local communities to guide students, staff, faculty and administration in Indigenous ways of knowing and being.

Text: The Science of Sound, third edition by Thomas Rossing. Addison-Wesley 2002 (on reserve in the UVic Library)

also on reserve: The Acoustical Foundations of Music by John Backus

The Physics and Mathematics of Waves by Mike Divell. An optional primer on the physics of sound. Assumes knowledge of calculus and some differential equations. Not required for this course, read only if you are interested!

Grading:

Quiz (1) 15%
Homeworks (5) 25%
Midterm exam 25%
Final exam 35%

We will cover most of parts I, II, III, IV, VI of Rossing in this course (18 chapters).
