What is Cookie-Bite Hearing Loss?

A study published in the Journal of Laryngology and Otology says that cookie-bite hearing loss is a type of sensorineural hearing loss, which occurs due to impairment in the auditory nerves. This hearing loss develops slowly, is permanent, and is more challenging to detect than other hearing loss types.


The term "cookie-bite" comes from the U-shaped pattern seen on an audiogram result for people with mid-range or mid-frequency hearing loss. This pattern looks like someone took a bite out of a cookie, which is how it got its name.


Humans can typically hear sounds from the range of 20 to 20,000 Hz.

People with cookie-bite hearing loss struggle to hear mid-frequency sounds, typically between 500 Hz and 2000 Hz, a range of sounds that are crucial for understanding speech and music. As a result, people may hear background noises like a slamming door but miss someone speaking nearby.

If the problem is not congenital, this condition develops gradually, starting in a person's 20s and worsening into their 30s or 40s. Because many sounds are still audible, it often goes unnoticed until it becomes severe, leading to delays in diagnosis and treatment.

Reasons Behind Cookie-Bite Hearing Loss

Genetic Factors: 

Cookie-bite hearing loss often runs in families. Genetic mutations, particularly in genes such as TECTA, COL11A2, and CCDC50, can lead to this condition.

Acoustic Neuroma: 

Acoustic neuroma is a rare and benign tumor that develops on the vestibulocochlear nerve, which is responsible for hearing and balance. This tumor can disrupt auditory signals and result in mid-frequency hearing loss characteristic of the cookie bite pattern.

Cookie-Bite Hearing Loss Symptoms

How Can Cookie-Bite Hearing Loss Be Diagnosed?

Diagnosing cookie-bite hearing loss involves taking an audiogram - a hearing test that displays results on a graph. The graph shows the softest sounds you can hear and highlights specific patterns, like the "cookie-bite" shape, that indicate mid-range hearing loss.


If the condition runs in the family, it’s often discovered during a child’s early hearing tests. However, if it develops over time, it may go unnoticed until it worsens, as it often starts with mild symptoms. If you have this type of hearing loss, others might notice your hearing issues before you do. Once diagnosed, it’s important to begin treatment quickly to prevent further complications.
