Sound and Hearing

Sound and Hearing

Author: Peter Beyersdorf November 26, 2008 Duration: 55:51
We continue to look at mechanical waves, focusing on sound and hearing, specifically the decibel units for sound level.

Step into a San Jose State University classroom from the fall of 2008 with Physics 50 Lectures @ SJSU. This series captures the live, unedited lectures delivered by Dr. Peter Beyersdorf, offering a genuine semester-long course experience. You’ll hear the actual explanations, student questions, and chalkboard sounds from those Monday and Wednesday afternoons, covering fundamental principles essential for both science and pre-medical tracks. The audio in this podcast is enhanced to clarify key diagrams and equations discussed during the sessions, making it a valuable resource for anyone seeking to solidify their understanding of core concepts. While it documents a specific academic term, the material explores timeless ideas in physics, presented with a clear and engaging teaching style. Whether you're a student revisiting the basics, a lifelong learner curious about how the physical world works, or an educator interested in lecture methods, this archive provides an authentic auditory window into university-level science education.
