As a child do you remember your parents telling you to turn the television or your music down so that you don’t blow your eardrums? Rather than risk losing your hearing, it can be quite advantageous to sufficiently protect your ears if you know that you will be around loud noises throughout your life.
There are several reasons as to why this particular type of hearing loss is incredibly prevalent but the most important reason is its rate of development.
Take a moment and determine what it would be like to be unable to watch your favorite film or to even hear your family members speak while at the dinner table. When you are exposed to incredibly loud sounds over an extended period of time, the inner structures of your ear become damaged, thus causing noise induced hearing loss.
The number one question that people who may experience noise induced hearing loss ask is whether both of their ears will be affected.
Another reason as to why it is so important to ensure that you were a sufficient amount of hearing protection while around loud environments is so that your ears are protected from being affected by other hearing issues.

Central hearing loss is due to a damage, malformation or infections of the neural pathways and the hearing centres in the brain.
Functional hearing loss is due to some psychogenic condition or maybe due to deliberate exaggeration of hearing thresholds for personal gains.
A hereditary disorder most commonly characterized by profound bilateral hearing loss due to vestibular and cochlear abnormalities and also associated with adolescent development of a goiter, Pendred syndrome is estimated to account for up to 10% of all hereditary hearing loss [1]. Pendred syndrome is a hearing loss spectrum disorder with a large range of severity of symptoms that varies between individuals. The reduced functional capabilities of mutant pendrin result in severe enlargement of the membraneous vestibular labyrinth, an elaborate system of interconnected canals ands membranous sacs within the temporal bone that are filled with endolymph.
While the mutations in an individual's SLC26A4 gene cannot be normalized to alleviate the effects of Pendred syndrome, modern medical technology has rendered the symptoms of the disorder manageable. In a study evaluating hearing outcome in Pendred syndrome with cochlear implant recipients, researchers evaluated the anatomical, audiological, and surgical complications associated with Pendred and the hearing outcome of the cochlear device implantation [6]. The SLC26A4 is located on the long arm of the 7th autosomal chromosome, in the 31st position.
Unfortunately it wasn’t an empty threat and your parents reminding you to keep the noise levels down to a minimum may have saved you from experiencing noise induced hearing loss.
According to the CDC, many different people throughout the world suffer from noise induced hearing loss whether they are adults or children.
Around 12.5% of individuals between the ages of 6 and 19 experience noise induced hearing loss.

Approximately 17% of adults between 20 and 69 years of age are affected by this detrimental medical condition.
Unfortunately these figures also represent the total number of people who have permanent damage to their hearing due to being exposed to an ample amount of noise. Noise induced hearing loss occurs over an extended period of time, therefore individuals do not realize the effect that it has on their hearing until it is too late. Now imagine what it would be like to be unable to hear these sounds at an incredibly slow pace, it would be horrible.
There is a high probability that you can lose hearing in both of your ears, but they will generally not be equal. One of the most common conditions that occur as a result of noise induced hearing loss is tinnitus. The abnormally enlarged vestibular aqueduct (EVA) results in a malformation of the temporal bone, however the abnormal temporal bone formation is not the underlying cause of the hearing loss associated with Pendred syndrome [5]. As a recessive gene, in order for the syndrome to manifest a child needs have two copies of the mutant gene, one copy inherited from each parent. Noise has become the number one cause of hearing loss throughout the world and it is an incredibly prevalent illness that is experienced by people of all different ages.
In today’s society, loud noises are just a part of every day events, therefore we have become desensitized to their danger. When we expose ourselves to loud and harmful sounds, whether at work or during our personal time, it can be severely detrimental to the well-being of our ears. At the beginning of the development of noise induced hearing loss a human will be able to process sounds near 4000 Hz. As an example, one ear may hear better than the other ear which is commonly known as asymmetric noise induced hearing loss. Tinnitus is classified as a ringing, hissing, or buzzing in the ear as a result of damage by extensive sounds.
Deafness at birth or in early childhood has disastrous effects on the child’s overall development. Some of the children classified as learning disabled or slow learners may have this type of hearing loss.
An affected individual inherits two copies of a disease-causing mutation in the SLC26A4 gene, one copy inherited from the mother and another mutant copy from the father [1].
The solute carrier gene family is made up of about 300 genes that encode for proteins that function in the transport of solutes into and out of the cell as well as transport between different components of the cell. Therefore both parents of an afflicted individual must have at least one mutant copy of the gene.

Whether you work in a factory with a lot of heavy machinery or if you are a musician who is constantly around loud noises, hearing loss is a current issue that is not to be taken lightly. Unlike other injuries such as a cut, there is no blood or visible signs to tell that our hearing is slowly disappearing due to loud noises. Towards the end of the deterioration they will only be able to process sounds between 500 and 3000 Hz. Asymmetric noise induced hearing loss can generally be seen in individuals who work with loud objects where the sound is focussed to one ear.
If you are affected by tinnitus, you will never be able to experience peace and quiet as there will always be a pestering sound in your ear.
There is no gender preference in autosomal inheritance as the gene is not located on the sex chromosomes.
As an example, a firing instructor who shoots right-handed will lose more hearing in their right ear than their left due to the fact that the muzzle is closer to the right ear.
Over 30 million adults suffer from tinnitus and are unable to focus their thoughts and emotions, unable to sleep, and unable to concentrate on everyday tasks and activities.
Pendrin is the transmembrane protein encoded by the SLC26A4 gene, that functions primarily in anion transport across the membranes of the cell.
Expressed in a variety of epithelial cells of the inner ear, thyroid, and kidney the pendrin protein is integral to inner ear formation [2]. Hearing loss incurred through the inheritance of mutant SLC26A4 varies in severity by individual.
The altered protein form of pendrin encoded by homozygous recessive mutant SLC26A4 genes displays significant loss of function and decreased ability to perform the anion transportation function typical of pendrin.
Inability to transport anions such as chloride, iodide, and bicarbonate across cell membranes results in abnormal concentrations of anions in epithelial cells [3,4]. Enlarged vestibular aqueduct; a radiological marker of Pendred syndrome, and mutation of the PDS gene.
Atrophic thyroid follicles and inner ear defects reminiscent of cochlear hypothyroidism in Slc26a4-related deafness.
