Ultrasonic sound generator

使用此工具启动不同频率的超声波声音

** Can I hear ultrasonic ringtones? **

Find out just how far your ears can hear into the range of ultrasonic ringtones. Pretty much everyone should be able to hear the lowest tone (8kHz). Many people should be able to hear up to around 14.1kHz, from around 17kHz upwards we get into the range that only the under 20's can hear! Take the test below

Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is not different from "normal" (audible) sound in its physical properties, except in that humans cannot hear it. This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz.

** How to use this app ? **

It's really easy to use this app, first launch the app, in the main screen you can see different buttons.

8 buttons to generate one ultrasonic sound and one button to stop all current sound.

- 10 kHz

- 12 kHz

- 15 kHz

- 16 kHz

- 17 kHz
