Hearing Resources

Your hearing is an essential part of a quality life: when you hear better, you live better.

When you are ready to take the steps towards better hearing, it’s important to choose the most qualified professional to assist you in developing a successful, healthy hearing plan.

An Audiologist is an expert in hearing loss. They have focused their career on helping those with hearing and balance disorders, and have earned a Masters or Doctorate in Audiology from an accredited university. The audiologist’s title is then Au.D or Doctor of Audiology.

An Audiologist is trained to evaluate the entire auditory system and to perform diagnostic assessments to rule out any medical issues that can have serious consequences. Your audiologist analyzes your health history, including factors such as medications, genetics, diseases, physiology, and exposure to noise to determine their effects on your hearing.

Being a good Audiologist involves more than holding an educational background and practical experience, however. An Audiologist also understands the importance of being a good communicator and great listener, and is capable of translating your experience into a technical solution for better hearing.

As someone with whom you’ll invest your time and money, it’s important to choose an Audiologist you can trust and are comfortable with to discuss your questions and concerns. An Audiologist will be a part of your life for many years to come, committing themselves to giving you the best hearing possible through follow up visits and consistent quality care.

hearing resourcesIn the U.S., both dispensing audiologists or fitters/dispensers of hearing aids are hearing aid providers.

In California, an audiologist is a doctor who meets state qualifications to practice clinical audiology, which is the application of scientific principles, methods and procedures for measurement, testing, appraisal, prediction, consultation, habilitation, rehabilitation, or instruction related to disorders of hearing and balance systems, relating to hearing loss.

Audiologists are qualified to assess and treat both adults and children. An audiologist must have at least a Master’s Degree (M.S., or M.A.) or a Doctorate Degree (Au.D.) in communicative sciences and disorders from an accredited college or university before they can become licensed in California.

A fitter/dispenser is someone who measures hearing using an audiometer and selects, adapts, and sells hearing instruments. In California, a fitter/dispenser must pass an exam given by the State Committee of Examiners in the Fitting and Dispensing of Hearing Instruments and be supervised by another fitter/dispenser for one year.  No college degree is required to be licensed, only a high school diploma.  Fitters/dispensers will often use the designator, “HIS” which stands for Hearing Instrument Sciences. Even a skilled dispenser can miss signs of ear disease or other disorders simply because of limited educational background. Using an audiology-based practice is the most effective path to good hearing, as audiologists are educated to perform a comprehensive examination to confirm or rule out the need for medical intervention.

Hearing begins when the outer ear, the visible portion of the ear that is on the outside of the head, channels sound waves down the auditory canal. This tube-like passageway is lined with tiny hairs and small glands that produce ear wax.
The middle ear lies at the end of the auditory canal. It is composed of the ear drum and three small bones, known by the layman as the hammer, the anvil and the stirrup. When sound waves hit the ear drum, it vibrates and, in turn, moves the hammer. The hammer moves the anvil, which moves the stirrup, transmitting the vibrations into the inner ear.

The middle ear functions to amplify sound, which is why significant hearing loss can result from any disruption in any of the parts.

The inner ear consists of the cochlea and the nerve of hearing. It converts sound waves into nerve impulses that travel to the brain via the movement of tiny hair cells. The brain, in turn, allows us to hear… as long as the message it is receiving is not distorted due to problems in the process just described.

Do you have a hearing loss? You’re not alone…

People with hearing loss are often embarrassed because they think that they are different or that they have a rare condition. The last MarkeTrak survey (2008) estimated that 34.25 million people report a hearing difficulty; that is more than 10 percent of the U.S. population.

Here are some general guidelines regarding the incidence of hearing loss:

• Three in ten people over age sixty have hearing loss.

• One is six baby boomers (ages forty-one to fifty-nine), or 14.6 percent, have a hearing problem.

• One in fourteen Generation Xers (ages twenty-nine to forty), or 7.4 percent, already have hearing loss.

• At least 1.4 million children (eighteen or younger) have hearing problems.

• It is estimated that three in one thousand infants are born with serious to profound hearing loss.

Hearing loss affects only “old people” and is merely a sign of aging.

Actually it is the reverse of what most people think. The majority (65 percent) of people with hearing loss are younger than age 65. There are more than 6 million people in the U.S. between the ages of 18 and 44 with hearing loss, and nearly 1.5 million are school age. Hearing loss affects all age groups.

If I had a hearing loss, my family doctor would have told me.

Not true! Only 13 percent of physicians routinely screen for hearing loss during a physical. Since most people with hearing impairments hear well in a quiet environment like a doctor’s office, it can be virtually impossible for your physician to recognize the extent of your problem. Without special training, and an understanding of the nature of hearing loss, it may be difficult for your doctor to even realize that you have a hearing problem.

The signs of hearing loss can be subtle and emerge slowly, or they can be significant and come on suddenly. Either way, there are common indications. You should suspect hearing loss if you experience any of the signs below.

You might have hearing loss if you…


• require frequent repetition.

• have difficulty following conversations involving more than two people.

• think that other people sound muffled or like they are mumbling.

• have difficulty hearing in noisy environments, such as conferences, restaurants, malls or crowded meeting rooms.

• have trouble hearing children and women.

• have your TV or radio turned up to a high volume.

• answer or respond inappropriately in conversations.

• have ringing in your ears.

• read lips or more intently watch people’s faces when they speak with you.


• feel stressed out from straining to hear what others are saying.

• feel annoyed at other people because you cannot hear or understand them.

• feel embarrassed to meet new people or from misunderstanding what others are saying.

• feel nervous about trying to hear and understand.

• withdraw from social situations you once enjoyed because of difficulty hearing.


• have a family history of hearing loss.

• take medications that can harm the hearing system (ototoxic drugs).

• have diabetes, heart, circulation or thyroid problems.

• have been exposed to very loud sounds over a long period or single exposure to explosive noise.

• Noise exposure

• Acoustic trauma

• Medication

• Age

• Do you have difficulty understanding the television?

• Do you avoid group conversations?

Noise is one of the most common causes of hearing loss, and one of the most common occupational illnesses in the United States. A single shot from a shotgun, experienced at close range, may permanently damage your hearing in an instant. Repeated exposures to loud machinery may, over an extended period of time, present serious risks to human hearing.

• Ten million Americans have already suffered irreversible hearing damage from noise.

• Thirty million are exposed to dangerous noise levels each day.

• The effects of noise on hearing are often underestimated because the damage takes place so gradually.

• Excessive noise damages the delicate hair cells in the inner ear. This damage results in sensorineural hearing loss and often tinnitus (ringing of the ears).

hearing resourcesWhat can you do?

• Limit exposure time in noisy activities.

• Wear hearing protection.

• Turn down the volume on the television, radio, stereos and MP3 players.

• Consult an Audiologist about what you can do to conserve the hearing you still have.

• Have your hearing screened annually.

• Be alert to hazardous noise. Prevention is critical!

Not all hearing loss can be corrected through the use of hearing aids or alternative listening devices. The type of hearing loss determines the specific treatment required.

There are four types of hearing loss:

Conductive:  This could be caused by something as simple as earwax buildup. A conductive hearing loss can be the result of a blockage in the external ear canal, or can be caused by any disorder that unfavorably effects the middle ear’s ability to transmit the mechanical energy to the stapes footplate. Generally, the cause of conductive hearing loss can be identified and treated resulting in a complete or partial improvement in hearing. Following the completion of medical treatment for cause of the conductive hearing loss, hearing aids are effective in correcting the remaining hearing loss.

Sensorineural: This is the most common type of hearing loss, and is caused when tiny hairs in the cochlea are missing or damaged. The reason for sensorineural hearing loss sometimes cannot be determined. It does not typically respond favorably to medical treatment, and it is typically described as an irreversible, permanent condition. Like conductive hearing loss, sensorineural hearing loss reduces the intensity of sound, but it might also introduce an element of distortion into what is heard resulting in sounds being unclear even when they are loud enough. Once any medically treatable conditions have been ruled out, the treatment for sensorineural hearing loss is amplification through hearing aids.

Mixed: This is a combination of conductive and sensorineural hearing loss. A mixed hearing loss can be thought of as a sensorineural hearing loss with a conductive component overlaying all or part of the audiometric range tested. So, in addition to some irreversible hearing loss caused by an inner ear or auditory nerve disorder, there is also a dysfunction of the middle ear mechanism that makes the hearing worse than the sensorineural loss alone. The conductive component may be amenable to medical treatment and reversal of the associated hearing loss, but the sensorineural component will most likely be permanent. Hearing aids can be beneficial for persons with a mixed hearing loss, but caution must be exercised by the hearing care professional and the patient if the conductive component is due to an active ear infection.

Central: Strokes and central nerve diseases are often the cause of this type of hearing loss.

When you arrive, you’ll be greeted by our staff and asked to fill out several forms, including personal information, medical history and insurance matters, as well as receive a privacy notice.

When the exam begins, your audiologist will review your personal information with you and ask questions about any hearing concerns you have.

Next, the audiologist will look into your ears using an otoscope. We can examine the ear canal and the ear drum, checking for any obstructions or other ear exterior ear problems.

hearing resourcesThe pure tone hearing test then begins. You’ll sit in our special soundproof booth. The audiologist fits you with headphones connected to an audiometer. The audiometer transmits a series of tones at various volumes to your ears to determine the threshold at which you can hear various sound frequencies. When you hear a sound, you’ll be asked to press a patient response button or raise your hand.

Next is speech testing, asking you to listen to a series of one and two syllable words at different volumes and then repeat them. Your audiologist will determine the level at which you can both detect and understand speech. We may also conduct a speech in noise test. This test determines how clearly you hear sentences in a noisy environment.

Test results are recorded on a form called an audiogram, which the audiologist reviews with you. Your audiogram shows your hearing loss in frequencies and decibels. You’ll see the type and degree of hearing loss, as well as the degree of normal conversational speech that you are able to hear. Your audiologist will interpret these results as they relate to your concerns about hearing. Once test results are obtained, we can suggest possible treatment solutions.

The Digital Revolution Has Arrived!

Digital Hearing Aid Features and Technology Levels

Dramatic improvements have been made to the form and function of today’s hearing aids. Digital technology enables hearing aids to deliver a more natural sound, similar to what some users used to hear before experiencing a hearing loss. Hearing aids now come is all shapes and sizes to accommodate your lifestyle, budget and cosmetic preference, with dramatic designs and colors to designs that are virtually invisible.

Digital Hearing Aid Features

Dual microphones allow you to hear better in noisy situations; some can even identify the source of the noise and reduce it.

Open Technology that keeps the ear canal unobstructed and eliminates the “talking in a tin can” effect.

Feedback Cancellation eliminates whistling

Hands Free Technology automatically adjusts to your listening environment, whether you speaking with a telephone, in a crowded room, or in windy conditions.

Your Audiologist can program your hearing aid via computer to closely match your individual needs

• Wireless Technology allows you to hear your mobile phone, television and home phone in stereo, directly through your hearing aid.

Do you hear a ringing, roaring, clicking, or hissing sound in your ears? Do you hear this sound often or all the time? Does the sound bother you a lot? If you answer “yes” to these questions, you may have tinnitus (tin-NY-tus).

Tinnitus is a symptom associated with many forms of hearing loss. It can also be a symptom of other health problems. Roughly 25 million Americans have experienced tinnitus. Some cases are so severe that it interferes with their daily activities. People with severe cases of tinnitus may find it difficult to hear, work, or even sleep.

What causes tinnitus?

• Hearing loss. Most people who have tinnitus also have some kind of hearing loss.

• Loud noise. Exposure to loud noise can cause permanent hearing loss and tinnitus. Continued exposure can make the tinnitus and hearing loss get worse.

• Medicine. More than 200 medicines, including aspirin, can cause tinnitus. If you have tinnitus and you take medicine, ask your doctor or pharmacist whether your medicine could be involved.

• Other potential causes. Allergies, tumors, problems in the heart and blood vessels, jaws, and neck can cause tinnitus.

What should I do if I have tinnitus?

The first step is to see an Audiologist for an evaluation. A careful history and audiometric testing will lead to the most likely causes and best treatment for your tinnitus. You may be referred to an ear, nose and throat examination to complete the diagnosis.

How will hearing experts treat my tinnitus?

Although there is no cure for tinnitus, Audiologists, scientists and doctors have discovered several treatments that may give you some relief. Not every treatment works for everyone, so you may need to try several to find the ones that help.
Treatments can include:

Hearing aids. Most people with tinnitus have some degree of hearing loss. Hearing aids create a dual benefit of enhancing hearing and masking or covering up the tinnitus. The majority of patients with tinnitus receive partial or complete relief from their tinnitus with the use of hearing aids.

Maskers. Tinnitus maskers are small electronic devices that look like hearing aids and are tuned to generate sound that masks or covers up the tinnitus. Like hearing aids, they may provide relief from the tinnitus, but will not enhance hearing and may interfere with understanding speech. Many types of devices, such as fans, radios and sound generators can be used as tinnitus maskers to help tinnitus sufferers to fall sleep or get back to sleep.

Medicine or drug therapy. Some tinnitus sufferers develop anxiety and other strong emotional responses to their tinnitus. Certain medicines may provide relief from these emotional reactions and provide some relief from the tinnitus. Other medicines and nutritional supplements have provided relief in some patients.

Neuromonics Tinnitus Therapy. This treatment uses a combination of testing, counseling and specialized masking to help you to effectively manage and gradually reduce your response to the tinnitus. This treatment can take six months or more to complete but has the highest rate of success.

Counseling. People with tinnitus may experience anxiety, depression and other psychiatric problems. You may be referred to a psychiatrist our counselor as needed.

Relaxing. Learning how to relax is very helpful if the noise in your ears frustrates you. Stress makes tinnitus seem worse. By relaxing, you have an opportunity to rest and better deal with the sound.What can I do to help myself?

Think about things that will help you cope. Many people find listening to music very helpful. Focusing on music might help you forget about your tinnitus for a while. It can also help to mask the sound. Other people like to listen to recorded nature sounds, like ocean waves, the wind, or even crickets.

Avoid anything that can make your tinnitus worse, such as smoking, alcohol and loud noise. If you are a construction worker, an airport worker, or a hunter, or if you are regularly exposed to loud noise at home or at work, wear ear plugs or special earmuffs to protect your hearing and keep your tinnitus from getting worse.

If it is hard for you to hear over your tinnitus, ask your friends and family to face you when they talk so you can see their faces. Seeing their expressions may help you understand them better. Ask people to speak louder, but not shout. Also, tell them they do not have to talk slowly, just more clearly.
