By understanding your child’s hearing loss you can understand how much the technology enables your child to hear, listen and talk.
Developing listening and language starts with appropriate prescription of digital hearing aids. There are different types of hearing loss and they are usually described in terms of the decibel level at different frequencies. The child will hear that you are speaking, but will not be able discriminate the quieter elements of conversation which carry a lot of meaning. Where decibels are talking about loudness, frequency is talking about the range or pitch of hearing. The frequencies that are measured by your audiologist are the important sounds for speech development. Hearing levels are usually plotted on an audiogram that identifies the decibels levels of loss and frequency range of loss. An audiogram is a graph which shows how loud (ie the decibel level) sounds have to be at each frequency for the child to hear them Audiograms represent the loss for the right ( red O ) and the left ear ( Blue X) on the graph since the loss can be different in each ear. Hearing levels are gained when the audiologists measures the response of the child to sounds going through the ear, middle ear and inner ear.
The audiologist will set up the digital hearing aid to match your child’s frequency and amplification needs. In this way only the frequencies required will be amplified so your child will hear soft sounds and loud sounds will be controlled so that they will have a comfortable listening experience and hear all the frequencies required. SENSORINEURAL - This loss occurs when there is damage to the inner ear mechanism (cochlea, vestibular system or auditory nerve). CONDUCTIVE - This loss occurs when there is a problem with the outer or middle ear and sounds are not transmitted properly. MIXED - This loss occurs with a combination of sensorineural and conductive components. Approximately 314 in 1,000 people over the age 64 have hearing loss, and 40 to 50 percent of people 75 years and older have hearing loss. Ten million Americans have suffered irreversible noise induced hearing loss, and 30 million more are exposed to dangerous noise levels each day. The audiogram is based on a logarithmic scale reported as a function of frequency (pitch) and decibels (loudness). Additional diagnostic measures include discrimination testing to assess speech audibility and understanding and middle ear function testing to help differentiate between a middle ear vs inner ear pathology.
It dawned on him that his left ear had developed a hearing impairment and his fear was confirmed when he visited a hospital. Dr Rachna Pande, a specialist in internal medicine at Ruhengeri Hospital, agrees with Dr Manirakiza saying, “There are various reasons for deafness acquired later in life. Dr Pande also says that viral infections such as herpes zoster, mumps, perforation of ear drum, drugs like quinine, gentamycin, degeneration of auditory nerve responsible for hearing, are some of the common causes.
However, the commonest cause of hearing loss is exposure to loud noise (either recreational or occupational) for a long period of time. At the same time, one may be confronted with hearing impairment as they begin to advance in age. Exposure to such sound over a long time, especially when it is done within close proximity can cause hearing loss.
In an article about Noise-Induced Hearing Loss, the US National Institute of Deafness and Other Communication Disorders (NIDCD) indicates that noise from heavy city traffic is approximately 85 decibels, motorcycles produce 95 decibels, while sirens produce about 120 decibels. At the same time, the treatability of a hearing loss also depends on its level (or severity). However, realistically experts say that hearing loss which comes as a result of ageing is always permanent and that it can only be managed. For instance, if hearing loss is as a result of wax or a foreign body, treatment can be as simple as removing wax or the foreign body. When you begin asking people to get closer to you in order to hear what they are saying, then you must visit the doctor.

According to the Ministry of Health, about one million people countrywide have hearing impairment. In the fight to keep your body healthy and functioning properly, minerals play an important role. Potassium-rich foods include: potatoes, spinach, lima beans, tomatoes, raisins, apricots, bananas, melons, oranges, yoghurt and low-fat milk. Folate rich foods include fortified breakfast cereal, liver, spinach, broccoli and asparagus.
Research conducted at the University of Michigan Kresge Hearing Research Institute has shown that people pretreated with magnesium (along with Vitamins A, C, and E) were protected from noise-related hearing loss. Scientists believe this is because magnesium combats the effects of free radicals emitted during loud noises – almost like a protective barrier for the delicate hair cells in the inner ear.
Foods rich in magnesium include fruits and vegetables, such as bananas, artichokes, potatoes, spinach and broccoli. Zinc boosts body’s immune system and is also responsible for cell growth and healing wounds, so it’s potentially helpful in warding off germs that cause the common cold and, ultimately, those pesky ear infections. Foods rich in zinc include beef, port and dark-meat chicken, cashews, almonds, peanuts, beans, split peas, lentils, oysters – and dark chocolate!
On a balanced diet, our bodies usually produce enough of these minerals to keep us healthy and functioning effectively. Our hearing organs perceive sound as pitch and loudness, respectively as frequency and intensity. Decibels (dB) are the unit used to quantify loudness (our hearing’s perception of sound intensity).
The severity of a hearing impairment depends on how loud a sound must be before an individual hears it. DiMarco uses the universal language of dance to change the hearing world’s perception of what it means to be Deaf – and he just might win the Mirrorball trophy in the process. Wearing hearing aids has been such a positive experience for Marie Redfern, she wants to encourage others with hearing loss to try them, too. When measured together by your hearing healthcare professional, dB and Hz tell the degree of hearing loss you have in each ear. Based on the outcome and the lifestyle information you provide, the hearing healthcare professional will be able to recommend a course of treatment, which may include the purchase of hearing aids and enrollment in aural communication classes. Pitch is similar to the difference we hear between a low note played on a piano and a high note. Most vowel sounds (a,e,i,o,u) in English are low frequency but many consonants, like s, t, k, are high frequency. We do this to provide information, support, and encouragement for families who wish to learn more about how their deaf children can learn to listen and talk. This is typically a permanent, non-medical type of hearing loss, and usually helped by amplification. In an article about hearing loss, WebMD, an American corporation that provides health news and advice, states: “In age-related hearing loss (presbycusis), changes in the nerves and cells of the inner ear that occur as you get older cause a gradual but steady hearing loss. It is now the norm to plug in earphones, ignore the world and blast music at almost an ear-drum-shattering volume. This could also explain why people who live within the city are more likely to suffer from noise-induced hearing loss. In fact, some of the treatable hearing impairments become irreversible because of the tendency to take health issues for granted.
Any injury, severe pain, discharge, tinnitus, should not be neglected because timely treatment of any of these symptoms can prevent deafness,” says Dr Pande.
In the case of drugs causing deafness, stopping the drug reverses the condition, says Dr Pande.
During a screening for hearing impairment early this year sponsored by Rwanda Otolaryngology Head and Neck Surgery Society (ROHNSS) in partnership with the Starkey Hearing Foundation, a US-based NGO, Jean Damascene Bizimana, the youth representative of the Rwanda National Union of the Deaf (RND), said it is crucial for people to turn up for screening exercises since the burden of being deaf is too heavy to carry.
Calcium builds strong bones the milk commercials tell us and zinc is an important mineral for boosting the immune system.

That’s important to your hearing health because fluid in the inner ear is dependent upon a rich supply of potassium, especially in that part of the ear that translates the noises we hear into electrical impulses the brain interprets as sound.
Studies have shown that adults over the age of 50 with low levels of folic acid in their blood are 34% more likely to develop presbycusis. Also, lack of adequate magnesium in the inner ear causes the blood vessels to shrink, depriving it of valuable oxygen. Some studies suggest it’s also effective in treating tinnitus in individuals with normal hearing.
Low frequency sound waves produce low pitched, bass sounds while high frequencies produce high pitched, whistle sounds. A pleasant conversation, for example, has the intensity of 60 dB, a lawn mower up to 100 dB. Technically speaking, it’s defined as having hearing loss between 26 and 40 dB in the speech frequencies. Don’t guess or try to treat your inability to hear with over-the-counter or mail order solutions.
The outcome of the evaluation is known as an audiogram, a graph of the softest sounds you heard during your test. Keep in mind, untreated hearing loss puts you at risk for developing a host of other health-related problems, including depression, dementia and Alzheimer’s disease. Learning to Talk provides more information about how to help your deaf child learn to listen and talk.
Your child will gain more from hearing normal pace of language including intonation, accent and clear context. Thresholds that fall in the yellow shaded area of the graph between 0dB - 25dB reflect normal hearing acuity. And yet call after call, and even though the speaker volume was at maximum, he couldn’t hear anything. The inner part, containing the nerve that works on both the hearing and general body balance is the most affected with deafness.
These include pricking ears with needles, matchsticks and pins, rinsing ears with water and exposure to very cold air.
Research in occupational medicine shows that the amount of tolerable noise for human beings falls below 75 decibels. It could be as simple as the need to increase the television volume higher than was formally normal or straining to hear responses during conversations. Some minerals, like the ones listed below, are also critical elements in protecting our hearing health.
As we age, those levels naturally drop and contribute to presbycusis – or age-related hearing loss. Zinc does interact antiobiotics and diuretics, though, so be sure to seek a physician’s advice before adding this mineral to your diet. The level of a shout close by would be about 80 or 90dB as would that of a lorry passing you in the street. That might be because the body uses folic acid to metabolize homocysteine, an inflammatory compound that reduces circulation. Your family physician may be able to refer you, or you can visit our online directory and find a trusted professional in your community.
Thresholds within the pink shaded area of 41dB- 70B reflect a moderate to moderately-severe loss. Good circulation is an important component in keeping the hair cells of the inner ear healthy and working properly.
