This simple application shows the tonotopic organization of the human cochlea.  How the program works: the input from the microphone is divided into several frequency ranges. The amplitude of a given range is mapped to the region of cochlea that is responsible for the process of converting the energy. It is not 100% accurate, and boundary frequencies may spread to several regions. Like in living cochlea, pure tones excite not only one region but many, although one region is excited mostly. ## Key features - Visualizes cochlear tonotopic organization - Processes microphone input - Maps frequency amplitude to cochlear regions - Demonstrates pure tone stimulation ## Frequently asked questions about Human Cochlea Simulator ### 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. ### When was the Human Cochlea Simulator last updated? The Human Cochlea Simulator was last updated on November 3, 2020, to version 2.0. ### Does the Human Cochlea Simulator have ads? No, the Human Cochlea Simulator does not contain advertisements, providing an uninterrupted learning experience for users. ### What is the user feedback on the Human Cochlea Simulator? Based on the available data, the Human Cochlea Simulator has received one rating of 1.0 stars, indicating a very low user satisfaction score. ## Version history (last 3 releases) ### 2.0 — 2020-11-03 New and improved look, more interesting information. ### 1.1 — 2017-11-10 Fixed minor bugs ### 1.0 — 2017-11-07 No release notes. ## More apps by Marek Porowski - [Auditory System Simulator](https://appshunter.io/ios/app/auditory-system-simulator/id1357978280) - [Mars Vs Melon](https://appshunter.io/ios/app/mars-vs-melon/id1566736042) All apps by Marek Porowski: https://appshunter.io/developer/1308045835 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
