Now, you can test that concept within a clean and easy-to-use interface. High Frequency Tones will allow you to generate any frequency up to 20,000 Hz – widely considered the upper limit to human hearing. Potential uses include: • Annoy your friends or classmates without tipping off the teacher or other adults. • Use it as a dog whistle or bug deterrent (both of whom have better hearing than humans!). • Ward teenagers away from an area. • Compete with your friends to determine who has the best hearing!
