The ear is a human auditory organ, which consists of three parts: the outer ear, the middle ear and the inner ear. When sound enters the ear canal through the outer ear, it will reach the eardrum, the boundary between the middle ear and the inner ear. Tympanic membrane is a very sensitive membrane, which can sense the vibration of sound and convert it into mechanical energy.
1, sound waves are introduced into the ear canal through the external auditory canal.
When sound waves are introduced into the ear canal through the external auditory canal, they will impact the eardrum and cause vibration. These vibrations are further transmitted to the inner ear through the ossicles, malleus, incus and stapes, where they are converted into nerve impulses and transmitted to the brain through auditory nerves for analysis. In the brain, these pulses are decoded into sounds that we understand, so that we can hear and recognize the surrounding sounds and sounds.
2, the role of tympanic membrane
In addition, the role of tympanic membrane is to protect the middle ear and inner ear from the influence of external acoustic pressure. If the eardrum is damaged or ruptured, it will lead to hearing loss and balance problems may occur. Therefore, it is very important to keep your ears healthy.
Including regular inspection of the condition of ears, avoiding excessive exposure to noise, and taking appropriate measures to prevent ear infections. Generally speaking, the eardrum plays a key role in the process of transforming sound waves into vibrations, enabling us to hear and understand the surrounding sounds.
Expand knowledge:
The ear is located behind the eyes. It has the function of receiving mechanical waves. It can convert mechanical waves and sound waves into nerve signals and then transmit them to the brain. In the brain, these signals are translated into sentences, music and other sounds that we can understand. The ear includes three parts: the outer ear, the middle ear and the inner ear.
Hearing receptors and position receptors are located in the inner ear, so the ear is also called position hearing device. Some people also list the outer ear and middle ear as appendages of audiometer. The external ear consists of two parts: auricle and external auditory canal. In addition, there are ear hairs and some glands on the skin of external auditory canal, and the secretions of glands and ear hairs have a certain blocking effect on the entry of foreign bodies such as dust.
