Mixed hearing loss transpires when you go through both conductive hearing loss and sensorineural hearing loss. In simpler words, when both your inner and outer ear are damaged, then the hearing loss is termed “Mixed Hearing Loss.”
The person’s ability to hear clearly and soundly gets alleviated as the impairment in the outer ear becomes ineffective to send the neural impulse to the inner ear. This further result in a dearth of auditory signals that is obligatory to be reached to the brain for interpretation and the brain fails to respond to the coming stimulations.
The inner ear loss or sensorineural component is treated as a permanent loss. Whereas conductive hearing or outer ear loss can be reserved in most of the conditions. The mixed hearing loss could be either unilateral or bilateral, depending upon your austerity of the situation.
The sounds are experienced as soft in volume and cumbersome to interpret as two main parts of the ear are out of function. Mixed hearing loss can ward off any of the levels of hearing loss.
Deformity and abnormalities in the outer ear, ear canal, or middle ear can block the ear functioning and make the person hard of hearing.
In case of effusion of perilymph or endolymph (fluids present in the inner ear) to the middle ear, it can also disrupt the pathway of the auditory nerve impulse to pass. This leads to an inability of the message to travel from ear to the brain. Hence, the brain is not able to comprehend the message.
Sometimes, ear infections like Otitis media, allergies, or infections in the ear could be some of the cause the conductive hearing loss.
People, who suffer from injuries over the head or head traumas, can also suffer from hearing loss. AS, sometimes, head injuries tend to either lead to internal bleeding or damage the interior organs of the ear.
Exposure to the extremely noisy and rowdy working or living conditions can also act as a cause. This tends to increase the normal human hearing capacity, making him/her desire to hear in louder volume as they are habituated to high standards of volume.
Deformity and eruption in the inner ear consisting of the cochlea and semicircular canals could be some of the major and general causes of sensorineural hearing loss (SNHL).
People who are suffering from mixed hearing loss may mumble and ineptitude to hear sound with ease and distinctly. These people usually miss out on some part of the speech. This could be any punch line or essence of the story. They often request to repeat or reframe the words or sentences for clarification and understanding of the context.
They generally tend to stare at people while they are talking either in the hope of comprehending the text or to lip read. But sometimes, this makes the other person a bit nervous and Spartan.
These people are usually dead on their feet when the day is about to end as they require more and extra effort in understanding what people have to say. They, moreover, have a bluffing tendency in order to hide their hearing disability and in the hope of saying the people to repeat the words again and again.
Although efforts have been made by the audiologist to cure the Conductive hearing loss, as being temporary in nature.
To correct the sensorineural hearing loss (SNHL), depending upon the severity of the situation, doctors either recommend you hearing aid or implantations in the ear.
Hence, either medical or surgical ways are adopted to cure an individual’s situation with the aim of providing the best possible relief.
It is important to consider that each and every case of mixed hearing loss is unique and in case of any suspects regarding the mixed hearing loss, it is recommended to visit an audiologist for better concern and to have the bigger picture of the condition.
Frequently Asked Questions:
Can Birth Defects Or Genetic Disposition Could Be The Reason For Mixed Hearing Loss?
Yes, mixed hearing loss either could be by birth or some genetic factors also had a vital role in mixed hearing loss. In some cases, it has been seen that the children have been born with the innate mixed hearing loss which can be treated later on.
Can Mixed Hearing Loss Be Unilateral?
Yes, mixed hearing loss can be unilateral or bilateral. Unilateral means the inability of only one ear to works adequately whereas; the other ear works perfectly well. Bilateral means, the deficiency of both the ears to work correctly.
What Is The Normal Age To Experience Hearing Loss?
According to the studies, hearing disabilities tend to start from the age of 65 and till the age people reach the age of 75, they are half deaf. They are quite common in elderly people as the sense becomes weaker with the age.
