About
This educational app visualizes the tonotopic organization of the human cochlea. It processes microphone input, dividing it into frequency ranges and mapping their amplitude to corresponding cochlear regions responsible for sound energy conversion. While not perfectly accurate, it demonstrates how pure tones stimulate multiple regions, with one being most excited.

FAQ
What is the Human Cochlea Simulator?
The Human Cochlea Simulator is an educational application that visually demonstrates the tonotopic organization of the human cochlea. It uses your device's microphone to analyze sound frequencies and show how they are processed by different parts of the cochlea.
How does the Human Cochlea Simulator work?
The app takes input from your microphone, divides it into various frequency ranges, and then maps the amplitude of each range to the specific region of the cochlea responsible for converting that sound energy. This illustrates how different frequencies are perceived at different locations within the cochlea.
Is the Human Cochlea Simulator accurate?
The application is designed to demonstrate the concept of tonotopic organization and is not 100% accurate. Like in a living cochlea, pure tones may excite multiple regions, although one region will be predominantly stimulated.
What devices does the Human Cochlea Simulator support?
The Human Cochlea Simulator is available for iPhone, iPad, and iPod devices, making it accessible to a wide range of Apple users.
What is the age rating for the Human Cochlea Simulator?
The Human Cochlea Simulator has an age rating of 12+, suggesting it is suitable for users aged 12 and older.
