Learn about Hearing Loss & Ringing in the Ears
Our ability to hear is not the same as our ability to understand. Hearing sensitivity is a function of the ear. Speech understanding is a function of the brain. The outer ear, ear drum, ossicles, cochlea etc. function to collect sound and transmit it to the auditory cortex of the brain. There the brain must translate what the ears have collected into something that it can understand. If hearing loss prevents the ear from picking up all of the sounds of speech then the amount of information that the brain has to work with becomes limited and speech understanding suffers. If this lack of stimulation goes unchecked for many years the brain effectively forgets how to process speech. It’s a case of use it or loose it and thus why early diagnosis of hearing loss and early intervention with the proper hearing aids is so important.
Hearing vs. Understanding
There are two primary components of speech; volume and clarity. These contribute to our understanding. The volume of words comes from loud, low frequency vowel sounds that we make with our vocal cords. The clarity of words comes from soft, high frequency consonant sounds that we make with our lips and teeth. If high frequency hearing loss prevents us from hearing the soft sounds at the beginning of a word and we only hear the loud vowel sounds, then we don’t know if the person speaking said, Hat, Cat, or Sat. We just hear, “at” and accuse the speaker of mumbling. This seems worse in a noisy place like a restaurant because all of the sound waves colliding in the air further exaggerate the condition and the auditory environment just seems like a dull roar.
Ringing in the Ears
Crickets, ringing, buzzing, static, humming are all symptoms of high frequency hearing loss. It may be louder or softer at times and is usually more noticeable when it’s quiet. Many people have it and simply learn to ignore it, but others can’t seem to ignore it and are bothered constantly. How can you manage it?
Tinnitus is a symptom, not a disorder by itself. The most common cause of tinnitus is hearing loss. This condition presents two simultaneous complaints: “I hear but I don’t understand” and “My ears buzz or ring.” There can be other factors involved that cause or contribute to tinnitus to lesser extents. High doses of aspirin, some prescription medications and excessive caffeine can all contribute to increased tinnitus, but by and large the most common condition I see in the office is hearing loss itself.
Hearing Loss and How Hearing Aids Make a Difference
Hearing aids used on a regular, daily basis can provide great improvement in not only hearing but understanding as well. Research shows that most people with hearing loss wait seven years between the time that they first start having problems and the time that they get a hearing test. In this time period, the brain is losing practice at understanding. If the hearing loss is too severe and goes on for too long there is always a chance that it can not be improved, but almost always, patients who choose to correct their hearing loss sooner rather than latter and who wear their hearing aids often will hear and understand speech much better.
An accurate examination can reveal exactly where the deficit lies along the spectrum of speech sounds and which type of hearing aid circuitry and programming will best aid the listener in regaining the ability to understand speech more clearly. This is where the experience and training of your audiologist in Conway comes into play in order to incrementally give the user the correctly prescribed settings, in the correctly prescribed amount of time so that the brain can be appropriately reintroduced to the subtle differences between consonant sounds.
Hearing loss is the 3rd most prevalent chronic condition in older adults behind hypertension and arthritis. The majority of hearing loss, 90%, in adults is sensorineural, for which hearing aids are the only treatment available. Hearing aids are also a viable treatment option for conductive hearing losses where surgery is not an option.
