The hearing range of the human ear is from 20 Hz to 20,000 Hz. This means that the average person can hear sounds that have frequencies within this range. Let's understand this answer in detail.

What is frequency?
Frequency is the number of vibrations or cycles per second that a sound wave produces. It is measured in Hertz (Hz). The higher the frequency, the higher the pitch of the sound.

The human ear and sound perception
The human ear is a complex organ that allows us to perceive sound. It consists of three main parts: the outer ear, the middle ear, and the inner ear. Sound waves are collected by the outer ear (which includes the visible part of the ear, called the pinna) and directed into the ear canal. These sound waves then reach the eardrum, causing it to vibrate.

The vibrations from the eardrum are transmitted to the middle ear, where three small bones called the ossicles (the malleus, incus, and stapes) amplify the sound. The amplified sound waves then travel to the cochlea in the inner ear.

The cochlea and frequency perception
The cochlea is a spiral-shaped structure in the inner ear that contains thousands of tiny hair cells. These hair cells are responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. Different regions of the cochlea are sensitive to different frequencies.

Hearing range of the human ear
The human ear can perceive a wide range of frequencies, but there are limits to our hearing ability. The lowest frequency that the average human ear can detect is around 20 Hz. This is known as the lower threshold of hearing. Frequencies below 20 Hz are called infrasound and are typically felt rather than heard.

On the other end of the spectrum, the highest frequency that the average human ear can detect is around 20,000 Hz. This is known as the upper threshold of hearing. Frequencies above 20,000 Hz are called ultrasound and are also typically not heard by humans.

Conclusion
In conclusion, the hearing range of the human ear is from 20 Hz to 20,000 Hz. This range allows us to perceive a wide variety of sounds, from low-pitched sounds like thunder to high-pitched sounds like a dog whistle. Understanding the limits of our hearing range helps us appreciate the incredible abilities of the human ear.
