There are two different types of hearing impairments, conductive hearing loss and sensorineural hearing loss.
A conductive hearing loss is present when the sound is not reaching the inner ear, known as the cochlea.
Dysfunction of the three small bones of the middle ear, the hammer, anvil and stapes may result in conductive hearing loss. A sensorineural hearing loss is one resulting from dysfunction of the inner ear, the cochlea, the nerve that transmits the impulses from the cochlea to the hearing center in the brain or damage in the brain. Another common reason for hearing loss due to hair cell damage is noise-induced hearing loss.
Total or near-total sensorineural deafness may be the result of congenital malformations, head trauma, inner ear infection, genetic factors, or long history of excessive noise exposure. In addition to type, hearing loss can be classified based on degree of severity.  In increasing levels of severity, hearing loss is classified as mild, moderate, moderately severe, severe, or profound. The other 44 chromosomes that are not sex chromosomes are called autosomes.  A disorder of a gene that is located on an autosome is referred to as autosomal. This type of loss is due to the inability of sound to pass through the outer and middle ear.
This type of hearing loss occurs when there is damage to the cochlea (inner ear) or to the auditory nerve that goes to the brain. Without amplification, the child can hear most conversations up close and in quiet environments, but is likely to miss parts of words. Until recently, children with unilateral hearing loss did not have their hearing loss detected until they were in school. The audiogram is a graph that represents how loud a sound at a specific pitch has to be for the child to hear the sound. Configuration of hearing loss - is the shape of the hearing loss due to the amount of hearing loss at each frequency. My post about Hearing Loss: Taking Good Care For Healthy Ears was about some common types of hearing loss, how they develop, how they can be prevented and often treated and tips to take care of your ear health so you can keep your hearing intact for as long as possible. Hearing loss is measured by degree, separated into levels related to a person’s sound thresholds. Depending on the type of hearing loss, whether it is sensorineural hearing loss, conductive hearing loss or mixed hearing loss, the treatment will vary.
Severe and profound hearing loss is characterized by the inability to clearly hear sounds below the 70dB HL. Depending on the type and severity of the hearing loss, a hearing implant may be used to stimulate the inner ear. If you or someone you know is suffering from hearing loss, reach out to your doctor for help right away.


Disclaimer"Be Healthy, Be Happy", this blog, does not provide medical advice, diagnosis or treatment. Sensorineural hearing loss occurs when there is damage to the inner ear (cochlea) or the hearing nerve. A comprehensive hearing evaluation is necessary to differentiate between types of hearing loss and appropriate treatment options. The mobility of these bones, or ossicles, may be impaired for different reasons and disruption of the ossicular chain due to trauma, infection or other process may also result in hearing loss.
Chronic ear infection can result in a defective eardrum or middle ear cavity, and often in addition to the conuctive hearing loss the individual may have a sensorineural hearing impairment. This is why hearing loss should be detected and treated as early as possible.  A hearing loss present at birth should be addressed by no later than 6 months of age.How severe does the hearing loss have to be to affect language development? Other causes of hearing loss, listed above, should be ruled out before investigating genetics causes.
The sound is prevented from passing through the middle ear due to a blockage such as wax, a foreign object in the ear canal, infection in the middle ear or malformation of the pinna, ear canal or middle ear bones. Sensorineural hearing loss cannot be medically or surgically corrected therefore this damage is permanent. There is a problem with the outer and middle ear and damage to the cochlea or auditory nerve. The possible effects of a hearing loss depends on degree of loss, early identification services, amplification, and parent involvement. If loss is from birth, spoken language and speech may not develop spontaneously, or could be severely delayed unless modifications and interventions are taken. The child may rely on vision rather than hearing as the primary means for communication and learning.
Now, with newborn hearing screening, unilateral hearing loss is detected during the first months of life. Usually frequencies of 250-8000 Hz are used in testing because this range represents where normal conversation speech occures, although the human ear can detect pitches from 20-20,000 Hz. Ranging from ‘mild’ to ‘profound’ levels, hearing loss can vary in severity from person to person based on the type of condition and specific circumstances surrounding the impairment. Cochlear implants are a type of implanted hearing device designed for people with sensorineural hearing loss. As every type of hearing loss can vary in degree and nature of disruption, it is best to consult with a specialist to see which implant option may be best suited for an individual. This is sometimes referred to as nerve deafness, but the medical term is sensorineural hearing loss. For more information on the evaluation procedure, please see the Basic Hearing Test section under the Hearing Evaluation tab.


Hearing impairments are categorized by their type - conductive, sensorineural or both, by their severity, and by the age of onset. This will often interfere with speech understanding, as it is in the high frequency range that we find the consonant sounds that are most important especially in noisy surroundings. A conductive hearing loss is usually correctable through medical management such as surgery, medication, or removal of the obstruction. Proper amplification and intervention should enable the child to hear and recognize most sounds. With early and consistent use of hearing aids, many children will be able to detect sounds such as speech. Speech and oral language will not develop spontaneously without modifications and intervention. Often, a patient suffering from hearing loss can be treated with surgery, medicine or hearing aid or assistive listening devices. With the use of standard hearing aids, many people suffering from mild to moderate hearing loss may vastly improve their hearing without surgery or medical attention. Bone conduction implants have also proven to work well for those experiencing with conductive or mixed hearing loss. Furthermore, a hearing impairment may exist in only one ear (unilateral) or in both ears (bilateral).
Head trauma, ear infections, tumors and toxic medications such as certain strong antibiotics and chemotherapeutics are other reasons for sensorineural hearing loss. The child is at risk for significant delays in spoken language speech understanding, language comprehension and voice quality. Spoken language is significantly delayed, abnormal speech patterns may develop and voice quality is usually diminished.
When surgery of medication are not helpful, the hearing loss can often be improved with hearing aids.
Hearing aids and other assistive hearing technologies can often help this type of hearing loss. Depending on the definition it could be estimated that more than 50% of the population over the age of 70 has impaired hearing. May have difficulty understanding spoken conversations coming from the side of the head that has the hearing loss.
