- Children with normal hearing in both ears generally perform better with auditory tasks and processing sound in their right ear up until puberty.
- Ears are completely individual just like fingerprints! Yahoo has even explored technology that could unlock a cell phone when held to the ear.
- Of the 206 bones in the human body, the six smallest are in your ears: three in the right and three in the left. Together, each three are about the size of a pencil eraser.
- The hearing organ, called the cochlea, has 16,000 microscopic hair cells called sterocilia.
- The unit used to measure loudness – the decibel - was named after Alexander Graham Bell, the inventor of the telephone.
- We turn the radio up when we drive on the highway and down when we are on side streets is due to the fact that those with normal hearing need sound levels to be nearly 10 decibels louder than background noise. This is referred to as the signal-to-noise ratio.
- Other than vision and proprioception (the ability to sense the orientation of your body in your environment), our primary organs of balance, known as the vestibular system, are located in the inner ear. There are three semi-circular, bony rings located on different levels which contain fluid that moves as we move.
- Ears are self-cleaning. Only the outer third of the ear canal produces ear wax (cerumen), which moves outward on tiny hairs as we move our lower jaw to talk or eat.
- Thunder is the sound accompanied by lightning, but often there is a delay between when we see lightning and hear the thunder. That’s because sound travels nearly 760 mph whereas light travels about 186,000 mph. This is why we see lightning before we hear thunder.
- The best way to measure the distance of lightning from your location is by counting the seconds (one Mississippi, two Mississippi…) between the lightning and thunder. For every five seconds you count, the storm is about one mile away.
Did you know the most frequent pediatrician visits, other than for well-child care, are for ear problems? And, did you know that the most common surgery performed on children in the U.S. is for “tubes in the ears,” which refers to Tympanostomy tube (myringotomy with pressure equalization – “PE tube”) placement is the most common surgery performed on children in the United States
For most people, hearing loss occurs very gradually. The process of getting hearing aids, however, is not gradual. You walk into the audiologist's office, and a few minutes later you're hearing! It takes the brain time to get adjusted to the new sounds you'll be hearing through the hearing aids. To make the adjustment process a little easier, start with easy situations and work your way up to more difficult listening environments.
Hearing loss may make conversational speech seem very soft, or may prevent a person from hearing certain speech sounds at all. This is why people with hearing loss often say they can hear people talking, but can’t understand what they’re saying. They may be able to hear some sounds, so they can hear the person’s voice, but the hearing loss is blocking out the sounds that are vital to understanding. Usually, when a person is diagnosed with a hearing loss, hearing aids are recommended. Hearing aids are designed to amplify the sounds that the person needs the most, the sounds that they are unable to hear due to the hearing loss. Unfortunately, hearing aids have limitations and will not restore hearing to normal. Hearing aids are only part of the hearing loss puzzle. The best solution to increase hearing and understanding at the same time is to pair hearing aids with effective communication strategies.
Language is the basis for all learning. Children first learn to communicate through eye contact, crying, vocalizing and gesturing. As they grow, they learn the language around them. Children then learn about their world through language by talking, playing and reading; parents and teachers use various forms of language to help children learn. Later, children learn about language as they grow older.
Your Cleveland Hearing & Speech Center (CHSC) audiologist can place an order for your hearing aids. Before you can order a hearing aid, you must have your hearing tested. Once this testing is done, you should talk with your audiologist to decide which hearing aids are best for you, your hearing loss, and your lifestyle. Next, the audiologist will take an impression of your ear. During this process, she will put a putty-like material in your ear for about five to ten minutes. This material will harden to the shape of your ear so the hearing aid company can make your custom hearing aid.
Infant hearing loss affects approximately 2-3 out of 1,000 live births (NIDCD).
As of July 2004, all babies born in the state of Ohio receive a free hearing screening before they go home from the hospital. The Universal Newborn Hearing Screening (UNHS) legislation has been helpful in detecting hearing loss sooner and allowing families to begin helping their babies earlier. Typically, hearing is tested at birth, and, if it’s normal, is not tested again until approaching age 4. This usually takes place on a visit to the pediatrician. Hearing is screened again when the child enters school. Many schools then alternate between vision and hearing screenings during the school-age years.
Impairments in hearing can happen in either frequency (the high or low pitch of a sound) or intensity (the volume of a sound), or both. For example, a person may not be able to hear very high-pitched noises like a whistle, or they may not be able to hear the TV unless the volume is turned up – or both. Hearing loss severity is based on how well a person can hear the frequency or intensities most often associated with speech. Severity can be described as mild, moderate, sever, or profound. Hearing loss can be congenital (occurring from the time of birth) or acquired (developing later in life after a period of normal hearing). Hearing loss can affect one or both ears – and in different degrees of severity in each ear. A loss that affects one ear is called a “unilateral” (one-sided) hearing loss. A loss that affects both ears is called a bilateral (two-sided) hearing loss.
When your hearing aids do not provide enough help in certain environments, or if you don’t wear hearing aids but need help hearing only in certain situations, you may want to consider an assistive or alerting device. Discuss with your audiologist which devices might be helpful to you. At CHSC, we offer a variety of devices and can you determine which is right for you.
