Listening capability and age
Are you over twenty years old?
It is said that people over twenty years old are less sensitive to high-pitch sounds!
As I mentioned before in the blog that the mosquito machine invented by British follows this principle. Today, it's your turn to experience a touch of it!
Please listen and see how high the pitch you can hear!
Here we go!
