The Sound Circuit

This sequence explores the auditory system, moving from the physics of sound waves to the complex anatomy of the ear and the psychology of pitch perception. Students will investigate how we localize sounds and analyze the physiological causes and prevention of hearing loss.

Wave Wonders

Students explore the physical characteristics of sound, correlating frequency with pitch and amplitude with loudness. They visualize sound waves and interpret wave graphs to understand how physical properties become psychological experiences.

The Mechanical Ear

Students trace the path of sound through the outer, middle, and inner ear. They focus on the mechanical amplification of the ossicles and the critical transduction process occurring in the cochlea.

Pitch Perfect Theories

Students compare and contrast Place Theory and Frequency Theory to understand how we perceive pitch. They explore the Volley Principle as a bridge between these two fundamental theories.

Sonic Spotlights

An investigation into how the brain uses binaural cues—time and intensity differences—to locate sound sources in space. Students conduct experiments to test the accuracy of sound localization.

Silent Signals

Students analyze the differences between conduction and sensorineural hearing loss. Through case studies, they examine the impact of noise exposure and the role of technologies like cochlear implants.
