Definition As Per The RPWD Act 2016
General Information About Hearing Impairments
In 2011, a study led by researchers from Johns Hopkins reported that nearly 20% of Americans 12 and older have hearing loss so severe that it may make communication difficult. The study also found that 30 million Americans had hearing loss in both ears while 48 million Americans had hearing loss in one ear. According to 2010 data from the National Institute on Deafness and Other Communication Disorders , approximately 17% of American adults report some degree of hearing loss. Of this group, 18% of American adults between the ages of 45 and 64 have experienced some degree of hearing loss. NIDCD estimates that approximately 15% of Americans between the ages of 20 and 69 have high frequency hearing loss due to exposure to loud sounds or noise at work or in leisure activities.
A hearing impairment can be caused by many physical conditions , and result in varying degrees of hearing loss. Generally, hearing impairments are categorized as mild, moderate, severe, or profound. An individual with a moderate hearing impairment may be able to hear sound, but have difficulty distinguishing specific speech patterns in a conversation. Individuals with a profound hearing impairment may not be able to hear sounds at all. Hearing impairments that occur in both ears are described as âbilateral,â and those that occur in one ear are referred to as âunilateral.â

Where The Concept Of Hearing Loss Percentage Comes From
Hearing loss percentage is a concept used to quantify the level of disability from hearing loss. It is an estimate of earning capacity as a percentage of what someone might be earning without a hearing loss. A 68% hearing loss corresponds to an average loss in income of 68%. This is the correct way to think about hearing loss percentage.
This concept is based on averages, and incomes will vary across the population of hard of hearing individuals.
The percentage is based on hearing thresholds, which cannot fully capture ones ability to understand speech and communicate. Therefore, in practice, some discretion goes into determining hearing disability.

What To Do With Your Test Results And Choosing A Hearing Solution
Seek the advice of a medical professional to examine your audiogram and provide you with treatment options for hearing loss. The audiogram will provide guidance on how to treat the condition by articulating what type of hearing loss you have, whether one or both ears have hearing loss, and how much hearing loss you have.
Complementing treatment with noise protection is always important.
Some treatments may include:
Whats The Definition Of Hearing Impairment
Hearing loss, or hearing impairment, is typically defined as having a limited or total inability to hear sounds. If you are unable to hear sounds under 25 decibels in volume, you are considered to be experiencing mild hearing loss. On the other end of the spectrum, an individual is considered deaf when he or she has absolutely no or very little hearing.
Legally, hearing impairment is usually defined at the state level. For example, many states will define hearing impairment as loss of 70 decibels or the ability to discern speech at 50 percent or less with aids. Special education laws define it as any hearing loss that affects the ability to learn that is not covered under the definition of deafness.
A hearing test administered by a hearing professional will help you determine if you are experiencing hearing loss, as well as the severity of your hearing loss.
What percentage of hearing loss means youre legally deaf or medically deaf? Is there some kind of universal point at which the line is drawn between hearing loss and deafness? Those might sound like philosophical, esoteric questions, but theyre not. Hearing loss labels affect whether you qualify for protection and can help you determine what treatment options are best for you.

What Is Considered Profound Hearing Loss
What is severe or profound hearing loss? According to WHO, if the quietest sound you can hear with your better ear is between 60 and 80 decibels, your loss is severe. It will be at least 80 decibels if your loss is profound. People with profound hearing loss cant hear sounds quieter than about 90 decibels.
Shortcomings Of The Hearing Loss Percentage Formula
The hearing loss percentage formula has several shortcomings.
- It is one single statistic that aims to summarise the overall hearing health situation of one individual. A lot of valuable information is lost in the process of calculating this value.
- Since hearing loss percentage is an average value, it does not tell us whether the hearing loss is flat , sloped, dented, or has a different shape.
- The formula disregards any hearing loss at or below 25 dB, while in reality, it is possible to see greatly reduced speech understanding even at relatively low thresholds.
- The inputs to the formula are pure-tone thresholds at four specific frequencies across a range from 500 Hz to 3,000 Hz.
- Pure-tone thresholds do not necessarily translate into our ability to understand speech or distinguish different sounds.

What Should You Not Do Before A Hearing Test
Dont let earwax get in between you and hearing the world around you. At least 2 days before your appointment for a hearing test, clean your ears of wax. Dont use cotton swabs or place anything in your ear smaller than your foot. Your ears can be easily damaged if you insert objects in your ear canal.

What Do Those Lines Mean On My Audiogram
An audiogram is a graph that shows the softest sounds a person can hear at different pitches or frequencies.
Asymmetrical hearing loss is when each ear has a different level or type of hearing loss. Each ear is represented by a different line on the graph. If your graphs or lines look different, you have asymmetrical hearing loss. This is more unusual and signifies that the causes of the loss in each ear are different and therefore must be treated differently. When asymmetrical hearing loss exists, it is best to have your ears checked out by an ENT doctor to ensure that you are a candidate for hearing aids and that no surgery or treatment is needed. The sample graph above reflects an asymmetrical hearing loss as each ear has different levels of hearing loss.
Symmetrical Hearing loss is most natural with age-related hearing loss. It implies that hearing loss is the same in both ears. If both lines or graphs look the same, you have symmetrical hearing loss. The graph below shows an audiogram reflecting symmetrical hearing loss.
Hearing Loss Percentage Calculator
How To Calculate The Hearing Loss Percentage?
Example 1
Mr A has a hearing loss of 60 dB in his left ear and 65 dB in his right ear.
Referring to the Hearing Loss chart above
60 dB hearing loss = 40%
65 db hearing loss = 48.55%
Let us insert these values in the formula
Hearing Disability Percentage= + =248.55/6= 41.42%
Mr A has a hearing loss of 41.42%, as per the RWPD 2016 guidelines, Mr A is eligible for the Disability Certificate as his hearing loss is above 40%.
Example 2
Mr B has a hearing loss of 55 dB in his left ear and 70 dB in his right ear.
Referring to the Hearing Loss chart above
55 dB hearing loss = 23%
70 db hearing loss = 57.10%
Let us insert these values in the formula
Hearing Disability Percentage= + =172.10/6= 28.68%
Mr B has a hearing loss of 26.68%, as per the RWPD 2016 guidelines, Mr B is not eligible for the Disability Certificate as his hearing loss is below 40%.
The easiest way to remember is that the hearing loss in the better ear should be equal or more than 60dB.

How Hearing Loss Is Measured
So how do you know if you have hearing loss and to what degree? Dont guess or try to treat your inability to hear with over-the-counter or mail order solutions. Instead, make an appointment with a qualified hearing healthcare professional. Your family physician may be able to refer you, or you can visit our online directory and find a trusted professional in your community.
In this case, this person cannot hear high-pitched sounds unless they are fairly loud. This will make hearing speech difficult. High-frequency hearing loss is a fairly common hearing loss pattern for people with age-related hearing loss. Others may struggle to hear low-frequency sounds and other sound ranges.
The hearing healthcare professional will administer a series of hearing tests. The outcome of the evaluation is known as an audiogram, a graph of the softest sounds you heard during your test. Heres an example of an audiogram of someone with mild-to-moderately-severe high-frequency hearing loss. As you can see, hearing thresholds in each ear are not always the same.
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 auditory therapy classes. Keep in mind, untreated hearing loss puts you at risk for developing a host of other health-related problems, including depression, dementia and Alzheimers disease.
What Is A Word Recognition Score
The last part of your audiogram that you will need to take a look at is the Word Recognition Score or WRS. This is located in a little box to the side or below your audiogram graph. It looks something like this:
The word recognition score is a measurement of your speech comprehension abilities. Your audiologist will test your brains ability to understand language by having you repeat sentences and words back to them. Its important to understand that the parts of your brain that process speech and hearing are separate. This means that fitting you with hearing aids wont necessarily improve your speech if it falls below a certain level. Every audiologist has their threshold below which they will not recommend someone to be a hearing aid candidatefor many it is 50%.
Bear in mind too, that the longer you go without hearing aids, the more your language muscle atrophies, lowering your score even more. After a certain point, this muscle ceases to work on a functioning level and the damage cannot be restored. All the more reason to get fitted with your Audicus hearing aid as quickly as possible!

What Are The Treatment Options
Its important to see your doctor if you have hearing issues that interfere with your day-to-day activities. Your doctor can do simple tests to check your ears and your hearing. If they suspect hearing loss, they may refer you to a specialist for further testing.
People who are hard of hearing can choose from among several different treatment options. Some options include:
- Hearing aids: Hearing aids are small devices that sit in the ear and come in a variety of types and fits. They help amplify sounds in your environment so that you can more easily hear whats going on around you.
- Other assistive devices: Examples of assistive devices include captioning on videos and FM systems, which use a microphone for the speaker and a receiver for the listener.
- Cochlear implants: A cochlear implant may help if you have more severe hearing loss. It converts sounds into electrical signals. These signals travel to your acoustic nerve, and the brain interprets them as sounds.
- Surgery: Conditions affecting the structures of your ear, such as the eardrum and bones of the middle ear, can cause hearing loss. In these types of cases, doctors may recommend surgery.
- Earwax removal: A buildup of earwax can cause temporary hearing loss. Your doctor may use a small tool or suction device to remove earwax thats accumulated in your ear.
There are several steps that you can take to protect your hearing. For instance, you can:
Why There Is A Common Misconception About Hearing Loss Percentage
Audiologists summarise hearing test results on an audiogram, which is often simplified to cover the range from zero to one hundred decibels.
Each value on an audiogram is a hearing threshold and is a different concept from the level of disability.
To see the dangers of confusing these concepts, notice that the decibel scale is logarithmic. For example, a sound at 36 decibels has twice the sound pressure of a sound at 30 decibels. The percentage scale, however, is linear.
During a hearing test, the audiologist measures your hearing thresholds, which should not be confused with a statistic used to quantify the level of disability caused by hearing loss.

What Is The Definition Of Legally Deaf
The medical definition of legal deafness is 66 to 85 decibels of hearing loss. On the scale of hearing loss degrees, this is considered severe. Anything over 85 decibels of hearing loss is considered profound. According to the U.S. Centers for Disease Control and Prevention, only those whose hearing impairment impedes their ability to comprehend speech and language are considered to have some level of deafness.
Those who are considered legally deaf have extreme difficulty in understanding speech, even with the assistance of hearing aids. At the profound level, hearing aids are not likely to contribute to any significant improvement in the ability to hear. It is estimated that as much as one-fifth of the American population had hearing loss severe enough that it impeded the ability to communicate. Although being legally deaf is associated with being medically classified as deaf, there are also social and psychological factors in considering the level of hearing loss. Cultural perception of the quality of ones hearing may lead to an individual being classified as deaf from a sociological perspective, even though the individual has not been diagnosed as clinically deaf. The same is true of individual psychology. It is possible for individuals to become convinced that they are deaf even though medical evidence suggests otherwise.

What Is An Audiogram How Does It Measure Hearing
An audiogram is the visual result of an audiometry hearing test administered by an audiologist or other health professional. This test measures potential hearing loss. The test uses a type of technology called an audiometer that can be connected to headphones, a speaker, or bone-conduction devices. The audiometer emits sounds that measure sound intensity and frequency.
You can get an audiometry hearing test in a quiet space at a doctors office. The test administrator will ask you to raise your hand or push a button when you hear a sound. The administrator will mark the sounds you hear on an audiogram.
