How High Can You Hear? Discover the Surprising Limits of Human Hearing<\/h3>\n

You may think you’re hearing every sound around you\u2014but what if some sounds have already slipped beyond the reach of your ears? This time, I used a smartphone app to test just how high a frequency I could actually hear. The results were more surprising than I expected and revealed just how different our ears can be.<\/p>\n

The Range of Human Hearing<\/h3>\n

Humans are generally said to hear sounds between 20 and 20,000 hertz (Hz)<\/b>. Hertz is the unit used to measure frequency, or pitch. The higher the number, the higher the sound.<\/p>\n

For reference, the highest note on a piano is around 4,000 Hz, while the buzzing of a mosquito is roughly 500\u2013600 Hz.<\/p>\n

But when I tested myself, I found that I could barely hear anything above about 15,000 Hz<\/b>. So much for matching the textbook exactly!<\/p>\n

A Simple Experiment Anyone Can Try<\/h3>\n

For this experiment, I used Narika’s Low-Frequency Oscillator CR-WEB<\/a>. This handy online tool can generate sounds from 0 to 20,000 Hz and works right from a smartphone or computer.<\/p>\n

In the video below, I used a tone generator app and gradually increased the frequency. You can follow along and see how far your own hearing reaches.<\/p>\n
