Facts About Hearing Loss
In terms of our ability to communicate with others, hearing is our most critical sense. Even relatively mild hearing loss can seriously disrupt how we interact and connect with others. Without healthy hearing, the consequences for our social and mental health — and physical health, in some cases — become greater, and overall quality of life can plummet. Healthy hearing requires a number of processes in the inner ear and brain to work properly in order to correctly interpret the sounds you hear. Inner-ear problems, or ear problems in general, can prevent crucial pieces of sound information from reaching the brain, leading to confusion and an inability to understand what is being said. Commonly, an ear problem in the outer or middle ear is referred to as a Conductive Hearing Loss, while inner-ear problems or brain-processing difficulties are referred to as Sensoriaural Hearing. These are two distinct types of hearing loss with differing treatment methods.
- Conductive Hearing Loss: This is a type of hearing loss that is typically the result of an infection or blockage in the outer or middle ear. Otitis media (middle-ear infections) can sometimes cause difficulty hearing due to a fluid buildup. Swimmer’s ear or a buildup of earwax may create a blockage outside the eardrum. This type of hearing loss is typically reversible once the infection or blockage clears, or once necessary surgery is performed.
- Mixed Hearing Loss: Individuals with mixed hearing loss typically suffer from some combination of SHL and a semipermanent conductive hearing loss, such as a malfunction of one of the ossicles (tiny bones that conduct sound) in the middle ear. Hearing may improve after the conductive portion of the hearing loss is resolved through treatment or surgery. SHL is usually permanent.
- Unilateral Hearing Loss: Hearing loss that occurs in only one ear is referred to as unilateral hearing loss. This can be present at birth, may happen spontaneously, or can occur over the course of several days (referred to as sudden hearing loss). Unilateral hearing loss may delay or otherwise affect speech and language development, and children may have difficulty identifying where sounds are coming from (localization), hearing speech in noisy situations, and hearing from longer distances. Children who are born with unilateral hearing loss can achieve success academically, economically, and socially by focusing on communication development.
- Sudden Hearing Loss: A sudden loss in hearing, either entirely or partially, within a 24-hour period — or immediately. Degrees of deafness vary, and while sudden hearing loss typically resolves itself within two weeks, it’s possible that hearing may never return. Treatment may include steroids to support the recovery of hearing, but patients who see no change within two weeks are unlikely to see improvement. Those who suffer from a sudden hearing loss should consult their physician immediately, as faster treatment greatly increases chances of a full recovery. About 85 percent of those who seek treatment will recover some of their hearing.
- High-Frequency Hearing Loss: Those with high-frequency hearing loss can usually hear vowels just fine, but consonant sounds — like f, s, t, and z — become difficult to hear. High-frequency hearing loss is often difficult to diagnose, because it occurs slowly over several decades, like most forms of sensorineural hearing loss. Early signs are an inability to hear higher-octave sounds, like a bird chirping or the voice of a woman or small child. Difficulty conversing in groups or hearing speech in background noise also indicate the possibility of a high-frequency hearing loss. Using hearing protection prior to being exposed to loud noises will help prevent high-frequency hearing loss, while hearing aids are an effective treatment.
Hearing loss is usually gradual, and by identifying these symptoms, you’ve covered step one in the diagnosis process. But only an accurate hearing exam can reveal if you are having difficulty with specific sounds or if your hearing as a whole is suffering.
