The simplest and free online tone generator for creating pure audio signals of any frequency from 1 Hz to 20000 Hertz (20 kHz), sine sound signal generator.

The range of human hearing is typically quoted as being from 20-20,000Hz ... No one can hear a pure 1 hz sinusoid, 20 hz is the minimum audible tone for humans.

2 окт. 2018 г. · Many things.. For example there are dog whistles that emit frequencies from 23000 to 54000 hz.. Much too high for even the best human ears ...

The correct option is A. Audible sounds. Sound waves above 20,000 Hz are ultrasonics. Sound waves below the frequency of 20Hz are infrasonics.

Sounds having frequency more than 20,000 Hz are called Ultrasonic sound. As this is above the normal hearing range for humans, we cannot hear ultrasonic sound.
