Hear in Maine is an Alpha One program addressing hearing aid need and acquisition within Maine. Audiologist is a person who holds a mater’s or doctorate degree in the field of Audiology. Hearing Aid Specialists are people who have been sponsored and trained by someone in the field of hearing aid distribution. The purpose of a hearing exam is to quantify and qualify hearing in terms of the degree of hearing loss, the type of hearing loss and the configuration of the hearing loss. The type of hearing loss is information that suggests the point in the auditory system where the loss is occurring. An Audiogram is a report that is generated by hearing tests which graph out a chart of your hearing loss. Hearing exams are generally covered by insurances, but you should always check before making an appointment to be sure.
More than 75 percent of all hearing aid repairs are due to moisture and earwax accumulating in the hearing aid. Hearing aid batteries normally last 7-14 days when the hearing aid is used 16 hours per day. The sizes of hearing aid batteries are listed below along with their standard number and color codes. For equipment needs such as amplified phones, large button phones, door bell alert system, alarm clock alert, flashing fire alarms, etc.
One in every 350 babies is born deaf or hard of hearing in Minnesota each year (approximately 200 total).
A child with a mild high frequency hearing loss will have trouble hearing and understanding soft speech, speech from a distance, and speech with background noise.
Minnesota's Early Hearing Detection and Intervention (EHDI) Program ensures that every baby who does not pass hearing screening has timely and appropriate follow-up. For more information about hearing loss, visit Minnesota's Early Hearing Detection and Intervention (EHDI) Program. Information on this website is available in alternative formats to individuals with disabilities upon request. Two of the fundamental parameters that describe a sound wave in numbers are pitch and amplitude. To get an idea of the decibel scale: 10 dB is 10 times more powerful than 0 dB, not 10 points greater. 0 dB is the loudness of near silence (a mosquito 10 feet away), while 120 dB is the loudness of a loud car horn heard from 1 meter away. 90 Decibels or a sound as loud as only a raised voice can cause gradual hearing loss (Refer to the hearing safety chart here).
Since the loudness depends on the medium, the maximum loudness a medium can propagate is dependent on its density.
For events like the Saturn V launch, volcanic explosion, nuclear bomb explosion, earthquakes, star-quakes the concept of sound doesn’t really apply anymore.
However, in the universe beyond earth, the starquake on the magnetar SGR 1806-20 registered 22.8 to 32 on the Richter scale. The ear is divided into three sections: the outer ear, the middle ear, and the inner ear.
The outer ear consists of the ear flap or pinna, the auditory canal and the outer layer of the ear drum.
The middle ear consists of the three small bones (hammer or malleus, anvil or incus, and stirrup or stapes). The inner ear consists of the semicircular canals, the cochlea, the cochlear nerve, and the vestibular nerve. When hearing loss results from a problem in the outer or middle ear it is called a conductive hearing loss. When hearing loss results from a problem in the inner ear it is called a sensorineural hearing loss.
Individuals can also have what is called a mixed hearing loss, which is a combination of a conductive hearing loss and a sensorineural hearing loss.
Long-term hearing loss from loud explosions, such as blasts from roadside bombs, may not be as irreversible as previously thought, according to a new study by researchers at the Stanford University School of Medicine. Using a mouse model, the study found that loud blasts actually cause hair-cell and nerve-cell damage, rather than structural damage, to the cochlea, which is the auditory portion of the inner ear.


The increasingly common use of improvised explosive devices, or IEDs, around the world provided the impetus for the new study, which was primarily funded by the U.S. More than 60 percent of wounded-in-action service members have eardrum injuries, tinnitus or hearing loss, or some combination of these, the study says. Permanent hearing loss from loud noise begins at about 85 decibels, typical of a hair dryer or a food blender.
In order to determine exactly what is causing the permanent hearing loss, Stanford researchers created a mouse model to study the effects of noise blasts on the ear.
After exposing anesthetized mice to loud blasts, researchers examined the inner workings of the mouse ear from the eardrum to the cochlea. Previous studies on larger animals had found that the cochlea was torn apart and shredded after exposure to a loud blast. Much of the resulting hearing loss after such blast damage to the ear is actually caused by the body’s immune response to the injured cells, Oghalai said. Noise is unwanted sound —barking dogs, loud music, passing traffic, lawn mowers, industrial noise. Water Protection Earplug is ideal for swimmers and surfers, this plug helps prevent ear infections and keeps water out of the ears while in the pool or ocean.
Damaged hair cells cannot send electrical impulses to the auditory nerve, and the message to the brain becomes unclear, or may not be sent at all. When going to places like restaurants, theaters, or traveling in a car, is it difficult to hear speech?
The training for an Audiologist consists of not only hearing aid selection and fitting, but also detailed study of the ear and its function. In Maine, a Hearing Aid Specialist is required to pass a written and oral exam in order to receive their dispensing license. The loss may be conductive (a temporary or permanent hearing loss typically due to abnormal conditions), sensorineural (typically a permanent hearing loss due to disease, trauma, or inherited conditions), mixed (a combination of conductive and sensorineural components), or a central auditory processing disorder (a condition where the brain has difficulty processing auditory signals that are heard). Performance will vary depending on the style and type of hearing aid technology you are using. With moderate hearing loss the child will have difficulty with conversations even at close distances.
We know that children who do not receive early intervention services may have communication difficulties.
That means, it is just a series of pressure changes [compressions and rarefactions] in a particular medium. Like I said before, the perceived loudness depends on your ear’s distance from the source, so the loudness of a lawnmower can range anything from 90 dB to as much as 110 dB if you stand 3 feet away from it. Our atmosphere can do nothing more than 190 dB, that, by the way, is enough to make you deaf or cause death. The magnetar released more energy in one-tenth of a second than our sun has released in 100,000 years. An event which thankfully took place 50,000 light-years away from earth. This could be good news for the millions of soldiers and civilians who, after surviving these often devastating bombs, suffer long-term hearing damage.
Twenty-eight percent of all military personnel experience some degree of hearing loss post-deployment. Stanford scientists did not find this in the mouse model and speculate that the use of older research techniques may have caused the damage.
The creation of scar tissue to help heal the injury is a particular problem in the ear because the organ needs to vibrate to allow the hearing mechanism to work. Studies show that over 40 percent of Australians are disturbed at home or lose sleep because of noise pollution. Noise levels, referred to as decibels on the (A) scale (written as dB(A)) are a good indicator of people’s response to noise.
We make personalized earplugs, whether it is for industrial noise, hunting, shooting or swimming. This plus is also very popular with dentist and dentist workers; best choice for anyone who needs to hear accurately. The earphone is pressure fit into the mould and provides increased comfort and directionality of sound, cuts out background noise as compared with the standard Head-Phone normally supplied with device.
It is recommended to get a copy of your Audiogram so that you can bring this with you to compare other brands, vendors, and services.
Most insurances will not help with the cost of hearing aids, but there are a few exceptions, so again it is always better to check to be sure.


It is extremely important to clean the entire hearing aid every time it is removed from your ear by wiping and brushing it.
You can buy them at most general retail stores (drug stores, grocery stores) and also via the internet. If your audiologist started you off with hearing aid batteries color coded orange, you can buy any brand of battery with the same color coding. An audiogram, which is a graph, illustrates the type, degree, and configuration of hearing loss.
If a child is identified with hearing loss, Minnesota's EHDI program helps families access appropriate and timely intervention, statewide services, and needed resources.
But, the amplitude of a sound wave determines how powerful it is; greater the amplitude, louder the sound. On this scale, 9 means total destruction (8.2 was measured during the explosion of the largest bomb ever, Tsar Bomba). Had it been even 10 light-years away, the energy released would have wiped off life on earth. The most devastating effect of blast injury to the ear is permanent hearing loss due to trauma to the cochlea. These vibrations get sent to the cochlea in the inner ear, where fluid carries them to rows of hair cells, which in turn stimulate auditory nerve fibers. State government regulations state that our maximum daily noise dose should be no more than the equivalent of 85dB(A) for eight hours a day. They also have desiccants to absorb moisture and fans to circulate air around the internal components of the hearing aid.
Batteries cost about one dollar each so on average, if you wear 2 hearing aids, expect to spend about $4 per month.
Ninety percent of babies who are deaf or hard of hearing are born to hearing parents and most often, they have no experience with hearing loss. To understand more about audiograms, visit American Speech-Language-Hearing Association: The Audiogram. For instance, sound cannot travel in a vacuum due to the absence of any medium, but it can travel much faster in solids than in air.
These impulses are then sent to the brain via the auditory nerve, where they get interpreted as sounds. The musician plugs come standard with colour marking for left and right ear and personal initial if required. Get in the habit of cleaning the hearing aid after each use and keeping the hearing aid in the dry-aid kit at night. That is the reason you can’t hear someone talking in space (yes, movies that show loud explosions in space, lie).
Normally, a decibel scale ranging from 0 dB to 130 dB is enough for measuring the loudness of most things. This is a very short lived pulse which doesn’t carry enough energy to do us any harm.
But the results of the study would prove true for anyone who is exposed to loud blasts from other sources, such as jet engines, air bags or gunfire.
Prolonged exposure to noise levels above 85dB(A) can damage inner ear cells and lead to hearing loss. If you answered yes to any of these questions, maybe it is time to get your hearing tested.
Also, the faster speed of sound in steel rails is exactly the reason why, you can tell a train is approaching, if you stick your ears to the rails (do not try this on electric rails).
After further exposure, a person may not fully recover their initial level of hearing — irreversible damage will have been done, causing deafness.
Even brief exposure to very high levels of 130dB(A) or more can cause instant, irreversible hearing damage.
