May was designated as the Better Hearing and Speech Month by the American Speech-Language-Hearing Association (ASHA) in 1927. The goals of Better Hearing and Speech month is to bring awareness to hearing and speech deficits, educate the population on how these issues effect the community, and empower individuals to take action if they suspect they have a speech or hearing deficit.
Hearing loss is the third most common health issue in the United States, effecting one in every eight people over the age of 12. Difficulty communicating with others can lead individuals to be withdrawn, negatively impacting them both socially and emotionally. The primary goal of an audiologist, when working with these patients, is to provide the tools they need to maintain an active lifestyle and minimize the effect of their hearing loss. The National Institute of Health (NIH) developed a short questionnaire* to see if you could benefit from having your hearing evaluated by an audiologist.
- Do you feel frustrated when talking to members of your family because you have difficulty hearing them?
- Do you have difficulty hearing or understanding co-workers, clients, or customers?
- Do you feel restricted or limited by a hearing problem?
- Do you have difficulty hearing when visiting friends, relatives, or neighbors?
- Do you have trouble hearing in the movies or in the theater?
- Does a hearing problem cause you to argue with family members?
- Do you have trouble hearing the TV or radio at levels that are loud enough for others?
- Do you feel that any difficulty with your hearing limits your personal or social life?
- Do you have trouble hearing family or friends when you are together in a restaurant?
If you answered “YES” to three or more of above questions, feel free to contact our clinic at (904) 339-0350 to schedule an appointment with a provider. Together you will develop an individualized plan to improve your hearing healthcare.

Sound and Taste: Where Is the Connection?
Synesthesia is a neurological phenomenon in which two or more senses interact; stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. One of the most common forms of synesthesia is grapheme-color synesthesia, in which people perceive individual letters of the alphabet and numbers to be “shaded” with a color. Other forms of synesthesia include correlating sounds with scents, sounds with shapes, or sounds with taste. This brings us back to: sound and taste, where is the connection?
Sound and Taste
Although not directly described as synesthesia, Charles Spence, an experimental psychologist at the University of Oxford has devoted much of his career specializing in research about the integration of information across the different senses. His work helps to explain why food can be more or less enjoyable depending on environmental features/atmosphere, colors, or in this case, sounds. Some of his most noteworthy work relates to how our perception of taste is effected by other sensory modalities, say sound, for example. As Spence writes, “Many of the food properties that we all find highly desirable – think crispy, crackly, crunchy, carbonated, creamy, and of course, squeaky (like halloumi cheese) – depend, at least in part, on what we hear”. Perhaps his most notable experiment in the field of cross-modal research was “The Role of Auditory Cues in Modulating the Perceived Crispness and Staleness of Potato Chips,” published in the Journal of Sensory Studies in 2004. From this research, Spence concluded that food can taste different depending on changes in sound. In general, higher pitched crisps with more crunch were reported to be more fresh and more desirable in taste. More recently, he found that higher-pitched music enhances sweetness. The evidence shows that when people are asked to match tastes with a specific pitch or musical instrument, the majority of people will match sweet-tasting foods with sounds having a higher pitch and the sound of the piano while matching bitter-tasting foods with lower pitched sounds and the sound of a brass instrument. Another thought: Ever think about why tomato juice or a Bloody Mary is more appealing on an airplane? Spence explains that the 5th flavor of taste, umami—a meaty, protein-like flavor described by the Japanese is actually enhanced in flight. According to research done by Spence, the loud engine noise of the plane at upwards of 85 decibels can influence how you taste food and beverage. It tends to suppress sweet and salty whilst enhancing umami, thus, you choose to drink tomato juice. Many drink options on planes tend to be sweet, hence juice and soda. Tomato juice is one of the only savory options. In fact, the German airline Lufthansa estimates people consume about as much tomato juice as beer aboard its flights! Spence’s suggestion to make more things taste appealing in air is to simply use noise-cancelling headphones. There is also work being done looking at different music people listen to on flights and how that can possibly contribute to how things taste. More work is being done in this area related to how restaurants can use sound to enhance the dining experience and food and beverage companies can utilize sound to better market their products.
Charles Spence recently published a book called Gastrophysics: The New Science of Eating. It is about the quirks of human perception and how they play out at mealtimes. https://www.amazon.com/Gastrophysics-Science-Eating-Charles-Spence/dp/0735223467

Learning About Cochlear Implants
If you or a loved one has a severe hearing loss and have tried hearing aids without success you may be a candidate for a cochlear implant. A cochlear implant is an implantable device that works together with an externally worn processor to bypass the damaged portion of the inner ear to deliver sound to the brain. Due to damage to the organ of hearing, many people find that hearing aids simply amplify sound and do not provide clarity or understanding.
To learn more about cochlear implants and other implantable devices please join Jacksonville Hearing and Balance Institute as we partner with Cochlear Americas to host an Open House event on Wednesday, March 7th, 2018. Representatives from Cochlear Americas will be available from 8am-3pm to answer questions, discuss candidacy and show models of cochlear implants and other implantable devices. A cochlear implant audiologist from Jacksonville Hearing and Balance Institute will be available from 10-12pm and from 1-3pm to discuss the evaluation and follow up process.
Mark your calendars for this wonderful and informational event. Feel free to drop by at your convenience any time between 8am and 3pm.

How Long Do Hearing Aids Last?
One of the most common questions we hear during a hearing aid consultation is “how long will these devices last?” It’s a smart question to ask given the investment that is required for a new pair of hearing aids. Many long-term hearing aid users will also start to worry that their devices will fail suddenly, leaving them without sound.
The average hearing aid user will upgrade their technology after 5 to 6 years. Some people will continue to use a hearing aid for 8-10 years, while others will choose to buy new technology after just two years. Let’s take a look at what might affect how long someone uses a hearing aid:
- Repairs: Like all electronics, hearing aids are more prone to requiring repairs the older they are. After the initial manufacturer’s warranty expires on the hearing aid (typically at 2 to 3 years), all repairs are out-of-pocket costs. Depending on what has gone wrong, repairs can range from $50 to $300+. In most cases, frequent repairs also mean time spent without the hearing aid, which can be very difficult for people who have grown dependent on their amplification. If repairs become too frequent, a person may opt to put their money towards updated technology. Also keep in mind that eventually, a manufacturer will run out of replacement parts for older models of hearing aids, so it become more difficult to get an 8-10 year old hearing aid repaired.
- Updates to technology: Hearing aid technology turns over very quickly. Most manufacturer’s release at least one new product every year, if not more often. It usually takes about five years for someone to notice a significant increase in sound quality and functionality of the hearing aid in order to justify upgrading technology.
- Loss/Damage: New hearing aids usually have a loss and damage warranty for 1-3 years. During that time, if you lose a device, the manufacturer will replace it with a new one for a small fee. Outside of the warranty, if you lose the hearing aid, you have to purchase a new one to replace it.
- Hearing changes: Most hearing aids can be reprogrammed to fit a large range of hearing levels. In rare instances of severe and sudden hearing deterioration, it is possible that someone would need to purchase a power device, which would be a new hearing aid designed to fit worsening hearing.
If you are wondering if newer hearing aids are appropriate for you, or you are noticing increased difficulties hearing, it’s a good idea to visit your audiologist. He or she can make recommendations for improving your current devices or moving forward with purchasing new technology. Remember that this is your journey, so don’t be afraid to ask questions and state your preferences. We look forward to helping you along the way.

This October is National Protect Your Hearing Month!
Over 12 million Americans have hearing loss as a result of exposure to noise, or noise-induced hearing loss. The audiologists here at Jacksonville Hearing and Balance Institute as well as audiologists across the country are encouraging individuals to protect their hearing by:
- Wearing hearing protection when around sounds louder than 85dB for 30 minutes or more.
- Turning down the volume when listening to the radio, the TV, MP3 player, or anything through ear buds and headphones.
- Walking away from loud noise.
How Does NIHL Occur?
Noise-induced hearing loss is caused by damage to the microscopic hair cells which are found in the inner ear. They are small sensory cells that convert the sounds we hear into electrical signals that travel to the brain. Once damaged, our hair cells cannot be repaired or grow back, causing permanent hearing loss.
How Loud is Too Loud?
The loudness of sound is measured in units called decibels (dB). Noise-induced hearing loss is caused by prolonged exposure to any loud noise over 85 dB, such as concerts, sporting events, lawnmowers, fireworks, MP3 players at full volume, and more. A brief exposure to a very intense sound, such as a gun shot near the ear, can also damage your hearing.
An environment is too loud and considered dangerous if you:
- Have to shout over background noise to be heard.
- It is painful to your ears.
- It makes your ears ring during and after exposure.
If you have decreased or “muffled” hearing for several hours after exposure, that is a sign of a temporary change in hearing, which can possibly lead to permanent hearing damage.
What Kind of Hearing Protection Does JHBI Offer?
To prevent noise induced hearing loss, the Hearing Center at Jacksonville Hearing and Balance offers a wide range of hearing protection devices that are custom-made to fit the unique curvature of an individual’s ear. These devices attenuate loud sounds and can be used in any environment that can potentially damage hearing sensitivity; from concerts, to sporting events, and even to the firing range.
If you are interested in meeting with an audiologist to discuss custom hearting protection options to fit your lifestyle, contact the Hearing Center at 904-399-0350 to make an appointment.
A Brief History
The introduction of the jet engine aircraft in the late 1940s and early 1950s raised concerns about hazardous noise and was one of the most important occurrences to the subsequent development of hearing conservation programs (Nixon, 1998). No sound of the jet engine’s magnitude had ever been routinely experienced in the military or by civilians. In 1952, the Navy conducted a study to evaluate the effects of the jet engine noise on personnel aboard the aircraft carrier USS Coral Sea. The study verified the seriousness of the high-intensity noise problem. In response to the problem, the NAS-NRC Armed Services Committee on Hearing and Bioacoustics (CHABA) was established in 1952 (Nixon, 1998). It was their job to examine the areas of (a) effects and control of noise, (b) auditory discrimination, (c) speech communications, (d) fundamental mechanisms of hearing, and (e) auditory standards. CHABA members were at the forefront of hearing conservation program (HCP) development. They began sponsoring and publishing reports related to noise in the military. They went on to publish a Memorandum No. 2 on “Hearing Conservation Data and Procedures” in 1956. The Memorandum described components of a hearing conservation program and provided recommendations for their implementation.
In 1956, the Air Force was the first to establish a comprehensive hearing conservation program. The Regulation was revised in 1973. Both were model programs after which many organizations within and outside the government were created (Nixon, 1998). In 1978, the Department of Defense Instruction (DODI) 6055.3 was published and contained requirements that attempted to make all hearing conservation programs uniform across services. By 1980, the three branches (Air Force, Army, and Navy) had established hearing conservation programs in compliance with DODI (Nixon, 1998). In 1987, the DODI was revised. The most current DODI is 6055.12, and ensures that all services have a hearing conservation program implemented and these programs should include: a) sound measurements, b) engineering control measures, 3) noise labels in hazardous areas/on equipment, d) issuance of hearing protective devices, e) appropriate education to all personnel working around hazardous noises, f) routine audiometric testing which is to be stored in the Defense Occupational and Environmental Health Readiness System (DOEHRS), g) access to materials, h) record keeping through DOEHRS, and i) program performance evaluations (DOD, 2010).
NIHL in the Military
Northeast Florida is home to many military installations, including Naval Air Station Jacksonville, Naval Station Mayport, Kings Bay Naval Base, Camp Blanding Joint Training Center, Naval Aviation Depot Jacksonville, and Marine Corps Blount Island Command, which together provide employment to more than 50,000 active duty, reserve, and civilian men and women. As of 2011, there were 2,226,883 military members in the United States serving (including active duty, National Guard, Air National Guard, and reserves). Within the military population, an estimated 60% of veterans returning home from war have a hearing loss (CDC, 2013). Disabilities of the auditory system, including hearing loss and tinnitus, are the third most common injury experienced by veterans (Helfer, Canham-Chervak, Canada, & Mitchener, 2010). As far back as World War II, handguns, rifles, artillery rockets, ships, aircraft carriers, vehicles, communications devices, and many more, have been sources of potentially damaging noise levels (Humes et al., 2006, p. 201). Hearing is critical to the performance of military personnel, and noise-induced hearing loss (NIHL) is a severe impairment that can potentially reduce military effectiveness.
Several studies have been conducted to document reports of military hearing loss and tinnitus and effects due to noise. Results from a study conducted in 2010 using data between 2003-2005, found that a total number of 88,285 hearing impairment and noise-induced hearing related injuries (NIHI) were documented—unspecified hearing loss, tinnitus, perforations of tympanic membrane, acoustic trauma, impairment of auditory discrimination, etc. (Helfer et al., 2010). Overall, NIHI visits were reported for 9.6 per 1000 personnel.
How Does NIHL Occur? How Can It Be Prevented?
Loud noises destroy the ear’s special cells, called “hair cells.” They lie within the sensory organ of the ear, called “the cochlea”. The cochlea cannot regrow new hair cells. Once they have become permanently damaged, they are no longer a useful part of the cochlea. Hair cells are important because they help translate sound into a signal the brain interprets, or “hears.” The hair cells can be damaged significantly by a single impulse sound — gunfire, for example, or by prolonged noise exposure at levels that are harmful to healthy hair cells (greater than 85 dB).
Prevention is key in helping to reduce the number of military members and veterans with NIHL. Hearing conservation programs are a step in the right direction. Hearing protection devices, such as passive and active earplugs and earmuffs will also aid in prevention when used properly. Engineering controls to help reduce excessive noise levels should also be implemented. Most importantly, education about the dangers of hazardous noise levels is paramount to further reducing the incidence of NIHL in military members and veterans. Over the past several years, all branches of the military have been making strides towards better education about hearing loss and taking steps towards providing the best hearing protection for soldiers.
For the general population, three strategies you can use for prevention are: 1) walk away- at further distances, dangerous noise levels are not as harmful to your ears, 2) turn it down- if you have the ability, make sure you are listening to things at safe levels, reference the dB level above, and 3) protect your ears- always have a pair of earplugs or muffs on hand when you go to concerts, loud sporting events, hit the shooting range, etc. And just remember, currently, there is no cure for hearing loss, so try to protect the healthy hair cells you have!
