Cartilage conduction can be useful for patients with disorders of the outer ear, including aural atresia (underdeveloped ear canal), where conventional air-conduction hearing aids cannot be used. The basic premise of cartilage-conduction hearing aids is that cartilage located outside the ear canal is vibrated, which allows the vibration to be ...
The folds of cartilage surrounding the ear canal are called the auricle. Sound waves are reflected and attenuated when they hit the auricle, and these changes provide additional information that will help the brain determine the sound direction. The sound waves enter the auditory canal, a deceptively simple tube.
The cartilaginous portion of the ear canal contains small hairs and specialized sweat glands, called apocrine glands, which produce cerumen . The bony part forms the inner two thirds. The bony part is much shorter in children and is only a ring (annulus tympanicus) in the newborn. The layer of epithelium encompassing the bony portion of the ear ...
The hollow region in front of the ear canal is called the concha. The ear canal stretches for about 1 inch (2.5 cm). The first part of the canal is surrounded by cartilage, while the second part near the eardrum is surrounded by bone. This bony part is known as the auditory bulla and is formed by the tympanic part of the temporal bone.
The cochlea is the part of the inner ear involved in hearing. It is a spiral-shaped cavity in the bony labyrinth , in humans making 2.75 turns around its axis, the modiolus . [ 2 ] [ 3 ] A core component of the cochlea is the organ of Corti , the sensory organ of hearing, which is distributed along the partition separating the fluid chambers in ...
However, they often rely on lip-reading even when they are using hearing aids. The most quiet sounds heard by people with severe hearing loss with their better ear are between 70 and 95 dB HL. Profound hearing loss - People with profound hearing loss are very hard of hearing and they mostly rely on lip-reading and sign language. The most quiet ...

The visible part is called the auricle, also known as the pinna, especially in other animals.It is composed of a thin plate of yellow elastic cartilage, covered with integument, and connected to the surrounding parts by ligaments and muscles; and to the commencement of the ear canal by fibrous tissue.
