MCAT Basics Podcast

Sound and Hearing

In this episode, we focus on the physiology of sound and hearing.

We begin by exploring sound-related concepts, including sound waves, pitch, ultrasound, and the decibel system. Next, we delve into the anatomy and physiology of the ear, providing a clear understanding of how we perceive sound. This material will appear in two of the four MCAT sections: the Bio/Biochem and Physics/Chemistry sections.
