Hearing loss can be explained by the following information, which is presented to you by foresthills audiology. Hearing loss is most of the time a natural happening but sometimes it can be caused by some reasons. Hearing loss and its effects can vary from person to person. The loss can be noticed at different pitches and frequencies of sound.
Symptoms Of The Hearing Loss
- Most of the time the individual who is suffering from conductive hearing loss may complain about muffed sound
- There are some changes that person feels the sound coming from a large distance
- There may be some rare cases of feeling of numbness in the outer ear.
- The hearing loss comes with the muffled speech and tinnitus in the person
Causes Of The Hearing Loss
- Congenital, the hair cells are abnormal from the birth of the person which result in hearing loss
- Damage to cells is another possible reason, which causes hearing loss. The damage may occur due to the infection or drug intake. Any kind of trauma along with the noise exposure also causes the damage of hair cells
- Presbycusis is the age relating cause of the hearing loss
- Most of the time the infection within the outer or middle ear becomes the cause of conductive hearing loss
- Complete blockage due to the ear wax is another major reason for this loss
- Deterioration of the ear bones can also because
- Otosclerosis also causes the conductive hearing loss
- The hole within the eardrum or damaged eardrum causes the hearing loss
- Absence of the outer ear or sometimes the absence of middle ear structure
- Damage to the inner ear
- Buildup of earwax
- Ear infection a
- abnormal bone growths
- Ruptured eardrum
- Loud noise
- Occupational noises
- Recreational noises
- Some medications
- Some illnesses
Types Of Hearing Loss
Sensorineural Hearing Loss
Moving ahead in knowing the types of hearing loss, the foresthills audiology is describing sensorineural loss. As the name is referring that, the issue is all about the sensory receptors within the hearing system. The loss is due to the issues in the cochlea along with the auditory nerve. The damage to the hair cells of the cochlea also causes sensorineural hearing loss. The damage reduces the chances of sound moving in the ear, which then reflects as the loss.
Conductive Hearing Loss
Within the list of the types of hearing loss, the first one under limelight is the conductive hear loss. The word conductive is referring the point that there is some problem with the conduction of the sound toward the ear.
The conductive hearing loss is actually the problem of the inner ear along with the cochlea. The type also involves the issues in the ear canal, eardrum along with the middle ear. However, there is no harm to the auditory nerve in the conductive hearing loss. The overall loss is caused by the bad conduction of the outer sound to the ear
Mixed Hearing Loss
Not contains its own symptoms and causes, because it is a mixture of the above two types. The mixed hearing loss is caused when conductive and sensorineural both reasons are available in a person. We can also say that it is the loss of the inner ear and as well as of the outer ear. The middle ear may also be affected along with the other two.
Some of the causes make the mixed hearing loss temporary. While on the other hand, some causes from the second type make it permanent. Do not panic, the foresthills audiology is working for the best treatment of mixed hearing loss.
Types Of Tests In Audiology
The type of testing is there to measure the speech reception within the person. The foresthills audiology explained that our hearing is directly connected with the speech when we are asked to react to sounds.
The speech testing can be performed in a noisy area and as well as at some quiet place. The Measuring one can identify the speech and background noise separation.
Furthermore, the foresthills audiology is there to perform the Tympanometry test. The purpose of the test is to check the movement of the eardrum in the presence of the air pressure. The movement is identifiable when there is proper fluid along with the wax buildup. The eardrum perforations and tumors may also affect the movement of the eardrum.
Acoustic Reflex Testing
The test is used to measure the muscle contraction within the middle ear. It is actually identified to determine the actual location of the hearing problem. The same testing process also identifies that which is the type of hearing loss from which a person is suffering.
Auditory Brainstem Response
It is the testing, which is there to determine the type of hearing loss from which a person is suffering. Most of the time, the test is used when there are symptoms of Sensorineural hearing loss. A person has to wear headphones and have to react to some certain sound. The person with the headphone should be sitting in a designed booth. In the testing, the audiologist determines the person’s response to the sound and then note down at the audiogram.
Within the list of the types of hearing tests, which are performed by foresthills audiology, is Otoacoustic emissions. In the process, the sound is produced by the certain vibrations of the hair cells within the inner ear. The process uses the probe, which is fitted with the microphone along with the speaker to stimulate the cochlea. The probe is used to measure the exact response to the sound vibrations.
The person with normal hearing is going to produce the emission. While on the other hand, there will be no sound when a person is facing hearing loss. It mostly happens when the loss exceeds the limit from 25 to 30 decibels.
