Answer 1

The correct answer is 20- 20000 Hz

A normal human ear can hear the sound of frequency 20 Hz.
A human can hear the sound of frequencies between 20 and 20,000 hertz (Hz).
People don’t always know when they’re exposed to the frequency below 250 Hz.
Pitch is measured in Hertz (Hz) and loudness is measured in decibels (dB).
Humans can generally hear starting at 0 dB. But sounds that are more than 85 dB can be dangerous for your hearing in the case of prolonged exposure.
Sounds with a frequency of 20 kHz and higher are referred to as ultrasound (or ultrasonic sound).

Important Points

A sound is a form of energy that produces a sensation of hearing in our ears.
It is a kind of disturbance that travels through a medium due to repeated vibrations of the particles of the medium about their mean positions.
The disturbance being handed over from one particle to the next.

Additional Information

Characteristic	Explanation
Amplitude	It refers to the extent to which the particles of a medium are displaced through which the sound wave passes. Amplitude determines the loudness of sound waves.
Wavelength	The distance between two similar points in a wave is called its wavelength.
Frequency	The number of waves passing through a point in one second is called the frequency of a wave. The frequency determines pitch.
