Hearing Test

Question 1

Known as the labyrinth?

Accepted Answer

Inner ear

Answer

The inner ear is commonly known as the labyrinth due to its complex and intricate structure. It consists of the bony labyrinth and the membranous labyrinth, which house the cochlea for hearing and the vestibular system for balance, forming a maze-like arrangement.

Question 2

Auricle is a component of

Accepted Answer

Outer ear

Answer

The auricle, also known as the pinna, is the visible, external part of the ear. It is a component of the outer ear, responsible for collecting sound waves from the environment and directing them into the ear canal towards the tympanic membrane.

Question 3

Which of the following is not a component of the inner ear?

Accepted Answer

Tympanic membrane

Answer

The inner ear consists of the cochlea, vestibule, and semicircular canals, which are crucial for hearing and balance. The tympanic membrane, or eardrum, is located at the boundary between the outer ear and the middle ear, and therefore is not a component of the inner ear itself.

Question 4

What is the sound frequency range of human can hear?

Accepted Answer

20Hz-20kHz

Answer

The typical range of sound frequencies that a healthy human ear can perceive is from approximately 20 Hertz (Hz) to 20,000 Hertz (20 kHz). Frequencies below 20 Hz are infrasound, and those above 20 kHz are ultrasound, both generally inaudible to humans.

Question 5

Which of the following is specifically aided by having two ears?

Accepted Answer

The directional nature of sound

Answer

Having two ears (binaural hearing) is essential for sound localization, which is the ability to determine the direction from which a sound originates. The brain uses subtle differences in the arrival time and intensity of sound waves at each ear to pinpoint the sound source, providing a crucial sense of spatial awareness.
