Losing some degree of hearing as you age is perfectly normal, as the body becomes less efficient at protecting and repairing cells, including the tiny hair cells in your ears. These hairs are capable of detecting sound wave vibrations and translating them into nerve impulses that the brain can interpret as sound.
While it may seem as though hearing loss would result in a decrease in the overall volume of all sound this is usually not the case.
Usually hearing loss will start in the higher frequencies, and when this occurs you may find it harder to hear hisses, whispering, or high-pitched scratches or screeches. Another early sign of hearing loss that often goes overlooked until it becomes an annoyance is tinnitus, a symptom that can be described as hearing a ringing, humming, buzzing, hissing, or chirping sound in your ears even when there is no sound present.
Hearing loss can make it difficult to comprehend speech because people tend to speak in varying volume levels and the quiet points can be misheard or inadvertently ignored altogether.
If you have a hard time understanding public speakers or engaging in conversations in restaurants or cafeterias while others around you seem to have no trouble hearing then you may be seeing the beginning signs of age-related hearing loss.
Hearing loss has an incidence of 1 in 250 births and over half of isolated childhood hearing loss has a genetic etiology, with many genes involved. A number of subpanels are available for individuals with a diagnosis or clinical suspicion of a specific hearing loss phenotype or syndromic condition, such as auditory neuropathy spectrum disorders, Usher syndrome, Pendred syndrome or hearing loss with EVA, Branchio-oto-renal syndrome, Waardenburg syndrome, or Wolfram syndrome. This test is performed by next generation sequencing using Agilent SureSelect capture followed by Illumina MiSeq sequencing of the coding regions and splice sites.
PCR analysis is performed to detect the presence or absence of a deletion spanning the GJB6-D13S1830 region of chromosome 13. This test does not detect variants in non-coding regions, aside from the splice junctions, that could affect gene expression and a few exons have been excluded due to technical difficulties. The Otogenome™ Test is an early intervention approach that sequences 70 genes in children with hearing loss.
Therefore, if you have a point on your audiogram that is charted very high and far to the right side of the graph, you are able to hear a high pitched sound at a very soft volume. Once you understand how to read an audiogram, you must then be able to understand how to interpret the results. By comparing your audiogram results to the ideal hearing range, you can determine the severity of your hearing loss. While it is always good to think positively, you do not want to misunderstand the results of your audiogram.


As Bob has been working in close proximity to loud squealing circular saws, his hearing has experienced a sharp decline in the high frequency region. Jeremiah is suffering from an illness or infection, which is causing fluid to build in his middle ears. Summary Statement: Provides a basic understanding of the nature of noise exposure in construction and details on how to set up a hearing conservation program to minimize hearing loss. When the hairs become damaged due to the affects of aging or an underlying condition then your ability to pick up sound in certain frequencies may be diminished. Typically an individual will experience a loss in a specific frequency, whether it be high or low, or both.
You may also have trouble distinguishing the “S” sound from the “TH” sound in English speech, so you may for example mishear words like “the” or “she”.
While most causes of age-related hearing loss are not a cause for concern, in some cases there are underlying conditions that could present serious secondary risks if left untreated. Gene variants can be inherited in an autosomal recessive, autosomal dominant, X-linked, or mitochondrial pattern. Detection of copy number variants (CNVs) encompassing 1 or more exons is performed using VisCap™ analysis followed by confirmation using an alternate assay. CNV analysis is only performed when data meets necessary quality standards and may not be available for all cases.
Regions with high sequence homology are included in this test if a unique Sanger sequencing assay can be designed to rule out false positive calls.
By offering such a broad test, we may be able to identify at-risk patients, long before the onset of disease. There will be points on the graph along all of the tested frequencies, showing the softest volume at which you were able to hear the tone. The left ear is represented by the letter X and the right ear is represented by the letter O. As you can see in the picture provided above, this yellow shaded area on the graph forms a banana-like curve. One of our hearing care professionals will help you read your audiogram, allowing you to better understand your hearing ability.
Your bone conduction thresholds show healthy hearing capabilities, meaning you may have a restriction in your middle or outer ear.


Due to ageing and noise exposure damage, people tend to experience a higher degree of hearing loss amongst the higher frequencies.
Many people focus very heavily on the frequencies they can hear well, while discounting the frequencies that are giving them trouble.
These results show that Jeremiah has a conductive hearing loss and that his inner ear is quite healthy.
While not all cases of age-related hearing loss are caused by the same factors, there are some common symptoms. You may also find it difficult to understand the starting or stopping points in speech, as these points are usually spoken in lower volume as the voice tapers off and the vocal chords retract. The mumbling or slurring may be more pronounced when more than one person is speaking at the same time.
The comprehensive approach of the OtoGenome™ Test now makes it possible to simultaneously screen 87 genes known to cause both nonsyndromic hearing loss and syndromes that can present as isolated hearing loss, such as Usher, Pendred, Jervell and Lange-Nielsen (JLNS), Branchio-Oto-Renal (BOR), Deafness and Male Infertility (DIS), Perrault, and Waardenburg syndromes. Sanger sequencing is used to fill in regions with insufficient coverage and to confirm clinically significant variants, excluding variants classified as likely benign or benign. If a bone conduction threshold is recorded, these results will be represented by brackets [ and ]. Within the speech banana diagram, you can see where common sounds occur at normal conversational volume. Once this condition is alleviated properly, sound will once again be able to easily pass through the middle ear to the cochlea. Furthermore, a positive result from this test may predict the onset of syndromic features (e.g.
When your hearing is deficient in a specific frequency, sounds in that frequency may sound loud and distorted because your brain isn’t getting a clear sound profile from the hair cells in the inner ear.
Some describe it as a low hum that sounds like a generator in the distance, while others hear a high-pitched constant ring. Tinnitus is a sign that the mechanics in your ear are not working properly and there is some type of feedback be created as a result.
