The results of a thorough hearing examination will be displayed in an audiogram, a chart displaying high and low-pitched sounds on opposite sides of an axis. When a person is suffering from hearing loss, a doctor will recommend treatment based on the severity of the condition. However, it is important to keep in mind that the strongest degree of hearing loss does not always correspond with the worst symptoms.
Moderately-severe hearing loss
People with moderately-severe hearing loss often have a hard time understanding people, especially over the phone. As the level of impaired hearing increases, people may become withdrawn, afraid to misunderstand conversations, or feel embarrassed to ask someone to repeat what they’re saying. Thankfully, hearing aids are available, including cochlear implants, to correct hearing problems. A formal audiogram, or hearing test, measures the range of decibels that people can hear. Normal hearing ranges between 0 and 20 decibels. People with normal hearing can pick out sounds as faint as human breathing, which is about 10 decibels.
People with moderately-severe hearing loss will find it difficult to follow a normal conversation, especially if the speaker is speaking at a relatively low volume. This means that the listener may need to repeat explanations to understand what the other person is saying. People with moderately-severe hearing loss cannot hear any sounds below 40 dB and will have to rely on lip-reading to understand conversations.
People with moderately-severe hearing loss will have difficulty understanding sounds in the range of 56 to 70 decibels. This includes conversations in restaurants, sounds from a vacuum cleaner, a loud shower, and the sound of an air-conditioning unit at 100 feet. People with moderately-severe hearing loss will also have trouble determining speech clearly. Fortunately, hearing aids can help people with this condition hear better and improve their quality of life.
When you visit a doctor for an appointment, you will need to explain the signs of your hearing loss and the symptoms you’re experiencing. You should write down what’s different about your hearing. If you can’t remember exactly what’s going on, ask a friend or family member to take notes for you. They can help you remember what to say and when. And they can help you remember the doctor’s appointment.
As the condition worsens, you may need to rely on lip reading to understand conversations. You may have to work harder than before to understand a conversation. Depending on your hearing condition, you may even need to get help from a specialist in this field. It’s not uncommon for people with hearing problems to avoid social situations altogether. Some also experience depression. If the condition worsens, people with moderately-sever hearing loss may experience debilitating health consequences.
In some cases, people with moderately-severe hearing loss can’t tell if they’re experiencing mild or severe hearing loss. However, they can tell if they can hear sounds of varying decibel levels. For example, a person with mild hearing loss may have trouble understanding conversations in a quiet room. However, in noisy environments, hearing sounds can be a challenge. If you’re not sure what you’re hearing, you can schedule an appointment with an audiologist.
Age-related hearing loss
This form of hearing loss can impact a person’s ability to hear and may negatively impact their quality of life. Fortunately, it can be treated by your healthcare provider, including an audiologist or hearing aid specialist. If you suspect that you may have an age-related hearing loss, visit your doctor to find out if you should get a hearing aid. In some cases, this type of hearing loss can be reversible, but treatment will vary depending on the extent of your hearing loss.
This type of hearing loss affects both ears and usually occurs gradually as a person gets older. It can be caused by genetics, diseases like diabetes, and medications like chemotherapy. Other factors can increase the risk of developing this form of hearing loss, including exposure to heavy metals and pollution. Some people are more susceptible to this form of hearing loss than others. While there are other types of hearing loss, age-related hearing loss is the strongest degree of hearing loss.
Those who suffer from this type of hearing loss may experience difficulty hearing high-pitched sounds, have difficulty understanding conversations in noisy places, or over the phone. This type of hearing loss is often accompanied by other problems and may even involve lip-leading or social bluffing. For more information, visit www.ncrar.org. If you suspect that you have age-related hearing loss, make an appointment with a physician today.
Symptoms of age-related hearing loss can be difficult to detect. People who suffer from this condition often withdraw from family and friends, and are easily misinterpreted as unresponsive or uncooperative. Unfortunately, many people with this condition go untreated and their hearing problems may progress to the strongest degree. Thankfully, there are solutions for age-related hearing loss. In some cases, hearing aids and special training are sufficient to correct the problem.
The highest frequency of age-related hearing loss typically occurs at the age of 50, with signs beginning at a younger age when frequencies above eight kHz are included. Researchers Lee et al.(2005) studied 188 older adults and analyzed their pure-tone thresholds with standard and extended high-frequency audiometry. The participants ranged in age from 60 to 81 years and were tested twice to 21 times over a three to eleven-and-a-half-year period.
Ototoxin exposure is another cause of hearing loss that is less common but can be deadly. It can occur from salicylates, aminoglycosides, and many other chemotheraupetics. In severe cases, exposure to ototoxins can result in a loss of hearing, dizziness, and even intracranial injuries. If your hearing loss is due to these conditions, prompt surgical intervention may be necessary.
Noise-induced hearing loss
Noise-induced hearing loss, or NIHL, is a degenerative hearing loss caused by prolonged exposure to loud sounds. It may happen immediately or over a period of time. In either case, it can have an effect on your ability to understand speech and understand others. It can be permanent or temporary, and affect both ears. There are several treatment options for NIHL, including medical management and communication therapies. If you suspect you are suffering from NIHL, it is important to seek the advice of an audiologist immediately.
This type of hearing loss affects a range of frequencies and can be classified as asymmetric, with one ear more affected than the other. This type of hearing loss also contributes to tinnitus and vestibular dysfunction. Compared to other hearing losses, noise-induced loss is usually more severe in the left ear. Fortunately, noise-induced hearing loss is largely preventable.
When you are exposed to loud noises, the noise in your environment can affect your ability to hear high-frequency sounds. During a hearing test, you can detect noise-induced hearing loss by a dip to the right, a phenomenon known as a noise-notch pattern. The symptoms of this type of hearing loss include difficulty hearing speech, difficulties understanding people’s voices, and complaints about loudness.
Although NIHL is caused by occupational exposure, it can also be caused by recreational, residential, and social noises. According to the World Health Organization, noise-induced hearing loss affects more than one-third of the global population, or more than 600 million people. Noise-induced hearing loss has been recognized as an occupational disease since the 18th century. In fact, the National Institute of Occupational Safety and Health (NIOSH) permits exposure to noise levels of 85 dB for eight hours a day. Fortunately, most workplaces do not exceed these limits.
In addition to reducing auditory processing, noise-induced trauma also causes the development of asymmetric NIHL. A study in 258 male soldiers found a strong correlation between asymmetrical NIHL and abnormal results on electromyography. The asymmetrical form of NIHL was associated with a reduction in caloric responses. It has been shown that the most severe and damaging effects were experienced by asymmetrical individuals, as compared to symmetrical NIHL.
Recent research in animals and epidemiology has provided further insight into the causes of NIHL. Exposure to high-frequency noise causes asymmetrical hearing loss. However, studies involving animals have shown that exposure to high-levels of noise accelerated age-related hearing loss. This may not be the case for humans, but the findings are worth investigating. But what we do know is that noise is damaging our hearing health, and that prevention is the first line of defense.
The acoustic reverberation rate (AUC) of the inner ear has been found to be the most common cause of noise-induced hearing loss. Studies have shown that constant exposure to loud sounds causes damage to these small hair cells and makes it difficult for our ears to hear. The damage caused to the inner ear can be permanent. In severe cases, the noise may even affect our brain and lead to permanent damage.
