The expertise of ear, nose, and throat specialists (or otolaryngologists) at University of Utah Health Care is used to diagnose and treat conditions of the ear, nose, sinuses, larynx (voice box), mouth, throat, head, and neck. One in 10 Americans has a hearing loss that affects his or her ability to understand normal speech.
The damage caused by noise, called sensorineural hearing loss or nerve deafness, can be caused by several factors other than noise, but noise-induced hearing loss is different in one important way, it can be reduced or prevented altogether.
Young children, who generally have the best hearing, can often distinguish sounds from about 20 Hz, such as the lowest note on a large pipe organ, to 20,000 Hz, such as the high shrill of a dog whistle that many people are unable to hear. Human speech, which ranges from 300 to 4,000 Hz, sounds louder to most people than noises at very high or very low frequencies. Lawnmower, shop tools, truck traffic; 8 hours per day is the maximum exposure to protect 90% of people. Chainsaw, pneumatic drill, snowmobile; 2 hours per day is the maximum exposure without protection. Sandblasting, loud rock concert, auto horn; 15 minutes per day is the maximum exposure without protection. Gun muzzle blast, jet engine; noise causes pain and even brief exposure injures unprotected ears.
Every gunshot produces a noise that could damage the ears of anyone in close hearing range. A ringing in the ears, called tinnitus, commonly occurs after noise exposure, and it often becomes permanent. Habitual exposure to noise above 85 dB will cause a gradual hearing loss in a significant number of individuals, and louder noises will accelerate this damage. For unprotected ears, the allowed exposure time decreases by one-half for each 5 dB increase in the average noise level.
The Occupational Safety and Health Administration, in its Hearing Conservation Amendment of 1983, requires hearing conservation programs in noisy work places. Ideally, noisy machinery and work places should be engineered to be more quiet or the worker’s time in the noise should be reduced; however, the cost of these actions is often prohibitive. When noise measurements indicate that hearing protectors are needed, the employer must offer at least one type of earplug and one type of earmuff without cost to employees. Earmuffs fit over the entire outer ear to form an air seal so the entire circumference of the ear canal is blocked, and they are held in place by an adjustable band. Simultaneous use of earplugs and muffs usually adds 10 to 15dB more protection than either used alone. Ordinary cotton balls or tissue paper wads stuffed into the ear canals are very poor protectors; they reduce noise only by approximately 7 dB.
Studies have shown that one-half of the workers wearing hearing protectors receive one-half or less of the noise reduction potential of their protectors because these devices are not worn continuously while in noise or because they do not fit properly. A hearing protector that gives an average of 30 dB of noise reduction if worn continuously during an 8-hour work day becomes equivalent to only 9 dB of protection if taken off for one hour in the noise. During the hour with unprotected ears, the worker is exposed to 1,000 times more sound energy than if earplugs or muffs had been worn.


Just as sunglasses help vision in very bright light, so do hearing protectors enhance speech understanding in very noisy places. Hearing protectors do slightly reduce the ability of those with damaged hearing or poor comprehension of language to understand normal conversation. It has been argued that hearing protectors might REDUCE a worker’s ability to hear the noises that signify an improperly functioning machine. If you have any of these symptoms, you may have nothing more serious than impacted wax or an ear infection, which might be simply corrected. If you suspect you suffer from hearing loss, consult an Ear, Nose and Throat Center physician at 801-328-2522. At the Ear, Nose and Throat Center, we offer same-day diagnosis with CT scan and perform all services and procedures in our nasal and sinus center. We use the latest technologies to ensure that procedures, surgeries and recovery are as fast and painless as possible. For questions about nose services and procedures, call 801-328-2522 to schedule a consultation with one of our nose specialists. Our doctors treat patients through both medical and surgical means providing facial plastic and reconstructive surgery, pediatric ENT, cochlear implants, and hearing aids as well as treatment for balance disorders, inhalant allergies, sinus and snoring disorders, voice and swallowing problems, and cancer of the head and neck. If you think you have grown used to a loud noise, it probably has damaged your ears, and there is no treatment—no medicine, no surgery, not even a hearing aid—that completely restores your hearing once it is damaged by noise. These funnel through the ear opening, down the ear canal, and strike your eardrum, causing it to vibrate. As a general rule, noise may damage your hearing if you have to shout over background noise to make yourself heard, the noise hurts your ears, it makes your ears ring, or you have difficulty hearing for several hours after exposure to the noise. When hearing impairment begins, the high frequencies are usually lost first, which is why people with hearing loss often have difficulty hearing the high pitched voices of women and children.
The scale runs from the faintest sound the human ear can detect, which is labeled 0 dB, to over 180 dB, the noise at a rocket pad during launch. This means that as decibel intensity increases by units of 10, each increase is 10 times the lower figure. Evidence suggests that loud rock music along with increased use of portable radios with earphones may be responsible for this phenomenon. Some people react to loud noise with anxiety and irritability, an increase in pulse rate and blood pressure, or an increase in stomach acid. You should also wear them when using power tools, noisy yard equipment, or firearms, or riding a motorcycle or snowmobile. This includes a yearly hearing test for the approximately five million workers exposed to an average of 85 dB or more of noise during an 8-hour work day. As an alternative, individual hearing protectors are required when noise averages more than 90 dB during an 8-hour day.
If the yearly hearing tests reveal hearing loss of 10 dB or more in higher pitches in either ear, the worker must be informed and must wear hearing protectors when noise averages more than 85 dB for an 8-hour day. Earmuffs will not seal around eyeglasses or long hair, and the adjustable headband tension must be sufficient to hold earmuffs firmly around the ear.


The better earplugs and muffs are approximately equal in sound reductions, although earplugs are better for low frequency noise and earmuffs for high frequency noise. This is because decibels are measured on a logarithmic scale, and there is a 10-fold increase in noise energy for each 10 dB increase. Even in a quiet setting, a normal-hearing person wearing hearing protectors should be able to understand a regular conversation.
However, it is essential that persons with impaired hearing wear earplugs or muffs to prevent further inner ear damage. However, most workers readily adjust to the quieter sounds and can still detect such problems. He moved to Utah from Washington in 1995 to attend the University of Utah Physician Assistant program.
The vibrations are passed to the small bones of the middle ear, which transmit them to the hearing nerve in the inner ear. Loss of high frequency hearing also can distort sound, so that speech is difficult to understand even though it can be heard. Thus, 20 decibels is 10 times the intensity of 10 decibels, and 30 decibels is 100 times as intense as 10 decibels. But even cap guns and firecrackers can damage your hearing if the explosion is close to your ear. Very loud noise can reduce efficiency in performing difficult tasks by diverting attention from the job. A maximum allowable while on-the-job followed by exposure to a noisy lawnmower or loud music will definitely exceed the safe daily limit. What you might notice is a ringing or other sound in your ear (called tinnitus), which could be the result of long-term exposure to noise that has damaged the hearing nerve. Patients often complain of chronic cough and posterior headaches if the sphenoid is involved. Here, the vibrations become nerve impulses and go directly to the brain, which interprets the impulses as sound: music, a slamming door, a voice, etc. A low pitch, such as a deep voice or a tuba, makes fewer vibrations per second than a high voice or violin.
People with hearing loss often have difficulty detecting differences between certain words that sound alike, especially words that contain S, F, SH, CH, H, or soft C sounds, because the sound of these consonants is in a much higher frequency range than vowels and other consonants.
They are available in a variety of shapes and sizes to fit individual ear canals and can be custom made.
Or, you may have trouble understanding what people say; they may seem to be mumbling, especially when you are in a noisy place such as in a crowd or at a party.
