Показать описание
10000 Hz sine tone to test your speakers or headphones.

Humans can detect sounds in a frequency range from about 18 Hz to 20 kHz. (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature); the upper limit in average adults is often closer to 15–17 kHz. If you “hear” frequencies lower than 18 Hz, you might just be hearing harmonic distortion.
If you can´t hear the tone in this Video, this might be because of your listening device.

I have heard this frequency 24/7 365 since 2003, constantly. Only the volume changes. I feel slight pressure when playing this video. Peace!
