If you have to shout over the noise to be heard by someone within arm’s length, the noise is probably in the dangerous range. Here are the warning signs:

  • You have pain in your ears after leaving a noisy area.
  • You hear ringing or buzzing (tinnitus) in your ears immediately after exposure to noise.
  • You suddenly have difficulty understanding speech after exposure to noise; you can hear people talking but can’t understand them.

We hear sound when delicate hair cells in our inner ear vibrate, creating nerve signals that the brain understands as sound. But just as we can overload an electrical circuit, we also can overload these vibrating hair cells. Loud noise damages these delicate hair cells, resulting in sensorineural hearing loss and often tinnitus (ringing in the ears). The cells that are the first to be damaged or die are those that vibrate most quickly—those that allow us to hear higher-frequency sounds clearly, like the sounds of birds singing and children speaking.

Studies have shown that concert  lovers who wore earplugs were roughly five times less likely to have some temporary hearing loss than those who didn’t wear them. The earplug-users also were less likely to suffer from tinnitus afterwards. Prolonged exposure to lawn mowers, power tools, motorised recreational vehicles, target shooting, sporting events and fireworks can potentially damage hearing. But you can avoid or minimise hearing damage by wearing earplugs or other ear protection. Your local hearing care professionals at ‘ My Audiologist’ can provide custom ear protection that is crafted to fit each unique ear. Custom protection ensures a proper, optimal fitting each time, further reducing the risk of unwanted noise exposure. We  can also provide a hearing test to determine your baseline hearing level and determine if you already have any hearing loss.

Single sided deafness can be caused by a number of things, from viral infections or thrombi to brain tumours  and is currently incurable and difficult to treat. Symptoms include difficulty localising sound (direction of sound source) have significant difficulty hearing in noisy situations, especially when the noise is comingssd4from their hearing side.  The noise becomes part of the speech and very difficult to separate. Technology has evolved as we now have sophisticated Contralateral Routing of Signals (CROS) and Bilateral Contralateral Routing of Signals (BICROS) .

Researchers have been studying brain plasticity in response to Single sided deafness.  Brain plasticity is the ability of the brain to modify its own structure and function in response to changes, such as disease,  within the body or external factors.  It is at the base of normal brain function:  it helps us to learn and change our behaviour  as children, and as adults can help us to overcome brain injuries, use prosthetic limbs and of course, as well as many other things – including hearing devices.

Researchers found that the spread of cortical activation was symmetrical across the hemispheres of the brain in normal-hearing subjects, while in those with the single sided deafness the spread of neuron activation was extended in one hemisphere and reduced in the other.  This discovery demonstrates plasticity in both hemispheres of the brain in SSD sufferers, and is an important step toward the possible development of biomarkers that will assist in the guidance of treatment choices. Ultimately, it may even be possible to use this plasticity to develop therapies to cure the condition: by using brain stimulation as a process to restore a normal interhemispheric relationship.  Additionally, it may be that scientists may be able to restore normal auditory processing, returning SSD sufferers to a life less affected by their hearing and communication handicap.

Researchers have found that older patients with hearing loss appeared better able to be balance when their poor hearing was enhanced with hearing aids. The study found that participants for the study used sound information coming through their hearing aids as auditory reference points or landmark to help maintain balance…..

Do you suspect your hearing is not as good as it had been and also have trouble with your balance.  Please call ‘ My Audiologist” on 07 3446 5845 for a  comprehensive hearing assessment and advise…..

Studies have shown that a healthy cardiovascular system—a person’s heart, arteries, and veins—has a positive effect on hearing. Conversely, inadequate blood flow and trauma to the blood vessels of the inner ear can contribute to hearing loss. The inner ear is so sensitive to blood flow that it is possible that abnormalities in the cardiovascular system could be noted here earlier than in other less sensitive parts of the body.” researchers found that audiogram pattern correlates strongly with cerebrovascular and peripheral arterial disease and may represent a screening test for those at risk. Researchers even concluded that patients with low-frequency hearing loss should be regarded as at risk for cardiovascular events, and appropriate referrals should be considered.Research shows that hearing loss is frequently associated with other physical, mental, and emotional health conditions, and that people who address their hearing loss often experience better quality of life. Eight out of 10 hearing aid users, in fact, say they’re satisfied with the changes that have occurred in their lives specifically due to their hearing aids—from how they feel about themselves to the positive changes they see in their relationships, social interactions, and work lives.
When people with even mild hearing loss use hearing aids, they often improve their job performance; enhance their communication skills; increase their earnings potential; improve their professional and interpersonal relationships; stave off depression; gain an enhanced sense of control over their lives; and better their quality of life.

There are many risk factors associated with dementia, but one of the most recently discovered correlations is a condition that few would consider as even related to the disease. Research has identified hearing loss as a potential indicator of the development of dementia. Compared with individuals with normal hearing, people with hearing loss are more likely to develop dementia. The findings are found in a study published in 2011 made by Frank Lin, otolaryngologist and epidemiologist at Johns Hopkins School of Medicine in the US. He and his team followed 639 patients for 18 years. None of the subjects had cognitive impairments at the beginning of the study, although some did have a certain degree of hearing loss. During the 18 years of follow up, 58 cases of dementia were diagnosed amongst the 639 patients. The researchers found that for older adults with hearing loss, brain tissue loss happens faster than it does for those with normal hearing. We “hear” with our brain, not with our ears. When we have a hearing loss, the connections in the brain that respond to sound become reorganised.

Fortunately, for many people, hearing aids can provide the sound stimulation needed for the brain to restore the normal organisation of connections to its “sound centre” so it can more readily react to the sounds that it had been missing and cognitively process them.

Researchers says un-addressed hearing loss not only affects the listener’s ability to “hear” the sound accurately, but it also affects higher-level cognitive function. Specifically, it interferes with the listener’s ability to accurately process the auditory information and make sense of it.

In one study, Wingfield and his co-investigators found that older adults with mild-to-moderate hearing loss performed poorer on cognitive tests than those of the same age who had good hearing. The sharpness of an individual’s hearing has cascading consequences for various aspects of cognitive function. Even if you have just a mild hearing loss that is not being treated, cognitive load increases significantly.One has to put in so much effort just to perceive and understand what is being said that you divert resources away from storing what you have heard into your memory. As people move through middle age and their later years, researchers suggest, it is reasonable for to get  hearing tested annually. If there is a hearing loss, it is best to take it seriously and treat it.
