Original Summary

I recently learned that you slowly lose the ability to hear higher frequencies with age, so I built a simple app for fun that lets you play messages that one age group might be able to hear, while another can't. You just type your message and set the range, and it plays it out as morse code. At a certain point there are sounds that comes out as loud and clear to some people, and can't be heard at all by others. It also varies from person to person and the ranges are not exact Let me know if you find it interesting and have any ideas of where else to take the idea   submitted by   /u/Dangerous-Tip182 [link]   [comments]
