After you get a hearing test, the results will be charted on an audiogram, which is a visual representation of your hearing ability.
Certain types of hearing loss are named after the shape they create on an audiogram. For example, low-frequency hearing loss is sometimes referred to as “reverse-slope hearing loss” because the shape of the line is opposite of the much more commonly-diagnosed high-frequency hearing loss. Another type of hearing loss known as “cookie-bite hearing loss” describes mid-range hearing loss that appears as a u-shape on an audiogram.
“It got that name because when a patient with this pattern of hearing loss has an audiogram and the hearing thresholds are graphed, the pattern is a ‘U’ that looks as if someone took a bite out of it,” explained Jordan Glicksman, MD, MPH, FACS, FRCSC, otolaryngologist, rhinologist, skull base surgeon, and part-time lecturer at Harvard Medical School.
What Type of Hearing Loss Is Cookie-Bite Hearing Loss?
Cookie-bite hearing loss is a form of sensorineural hearing loss. That means it is caused by damage to the cochlea or auditory nerve as opposed to being caused by a blockage or deformity (which is known as conductive hearing loss).
What Sounds Do People with Cookie-Bite Hearing Loss Miss?
Most people with cookie-bite hearing loss can still hear high-frequency noises like birds chirping and women’s and children’s voices, as well as low-frequency sounds like thunder and men’s voices. As stated above, it is mid-range sounds that are most affected.
Unfortunately, a lot of human speech sounds fall in the mid-range – that is, between 500 Hz and 2,000 Hz. People with this type of hearing loss don’t necessarily have difficulty making out people’s voices, but have a hard time deciphering many words and sounds.
What Are the Symptoms of Cookie-Bite Hearing Loss?
Common symptoms of cookie-bite hearing loss include raising the volume on the TV much louder than others prefer, having difficulty hearing speech in crowded environments and overall experiencing trouble communicating. It is often the case that the loved ones of someone with this type of hearing loss suspect something is amiss.
