To arrange the components involved in the reception and transmission of sound waves from the eardrum, we can follow these steps: 1. **External Auditory Canal**: Sound waves enter the ear through the external auditory canal, which is the outermost part of the ear. 2. **Eardrum (Tympanic Membrane)**: The sound waves then hit the eardrum, causing it to vibrate. This is the first point of mechanical reception of sound. 3. **Malleus**: The vibrations from the eardrum are transmitted to the first of the three small bones in the middle ear, known as the malleus (or hammer). ...

The correct path followed by sound waves from external ear to inner ear is

Given below are some of the process which takes place in our ear when we are exposed to any sound. Arrange these in the correct order of sequence. (a)The eardrum vibrates the transmits the sound wave to the ear ossicles. (b) Vibration travel from oval window to the fluid of cochlea. (c) Ripples in the basilar membrane band the hair cell against the tectorial membrane (d) Generation of waves in the lymphs. (e ) sound waves are collected by the pinna. (f) generation of nerve impulse and transmission through auditory nerves to the brain

Read the following statements and find out the incorrect statements. a. Anatomically, the ear can be divided into three major sections called the outer ear, the middle ear and the inner ear. b. The outer ear consists of the pinna and external auditory meatus (canal). c. The tympanic membrane (ear drum ) is composed of connective tissue covered with mucus membrane outside and with skin inside. d. The ear ossicles reduces the efficiency of transmission of sound waves to the inner ear. e. The pinna collects the vibrations in the air which produce sound.

Name the structures in sequence which transmit the sound induced vibrations from the ear drum to the endolymph of the internal ear in mammals.

Largest ear ossicle is (a) Incus (b) Malleus (c) Stapes (d) Cochlea

When a sound wave enters the ear, it sets the eardrum into oscillation, which in turn causes oscillation of 3 tiny bones in the middle ear called ossicles. This oscillation is finally transmitted to the fluid filled in inner portion of the ear termed as inner ear, the motion of the fluid disturbs hair cells within the inner ear which transmit nerve impulses to the brain with the information that a sound is present. The theree bones present in the middle ear are named as hammer, anvil and stirrup. Out of these the stirrup is the smallest one and this only connects the middle ear to inner ear as shown in the figure below. The area of stirrup and its extent of connection with the inner ear limits the sensitivity of the human ear consider a person's ear whose moving part of the eardrum has an area of about 50mm^2 and the area of stirrup is about 5mm^2 . The mass of ossicles is negligible. As a result, force exerted by sound wave in air on eardum and ossicles is same as the force exerted by ossicles on the inner ear. Consider a sound wave having maximum pressure fluctuation of 4xx10^-2Pa from its normal equilibrium pressure value which is equal to 10^5Pa . Frequency of sound wave in air is 332(m)/(s) . Velocity of sound wave in fluid (present in inner ear) is 1500(m)/(s) . Bulk modulus of air is 1.42xx10^5Pa . Bulk modulus of fluid is 2.18xx10^9Pa . Q. If the person is using an hearing aid, which increase the sound intensity level by 30 dB, then by what factor the intensity of given sound wave change as perceived by inner ear?
