Cookie-Bite Hearing Loss: Reasons Behind It, the Treatments

A person can fall victim to hearing loss problems at any point in their life, no matter what type of hearing loss. Any hearing loss can profoundly affect the way of life of a person, and there are hearing loss problems of various kinds. Hearing loss can be age-related, or can be caused due to exposure to loud noise, or can be hereditary. Hearing loss can be temporary, while the others are permanent and you won't fully cure them. Hearing loss problems can also be divided into 5 degrees, ranging from mild to profound.

There are also some unique forms of hearing loss, and “Cookie Bite Hearing Loss” is one of them. Cookie Bite Hearing Loss is relatively uncommon, as it doesn’t occur as much as other hearing loss such as age-related hearing loss, or noise-induced hearing loss. Mid-range hearing loss is referred to as Cookie Bite Hearing Loss, and this term has derived from the shape of the audiogram result of a test taken by a mid-range hearing loss patient.

What is Cookie Bite Hearing Loss?

Research published in the Journal of Laryngology and Otology says that Cookie Bite Hearing Loss is a type of sensorineural hearing loss, and sensorineural hearing loss problems are permanent types of hearing loss. So, it occurs due to impairment in the auditory nerves. This hearing loss is quite unusual, as it affects particular sounds a person will hear. And it gets developed slowly and is more challenging to detect than other hearing loss types.

As said earlier, the name comes from the shape created on an audiogram result, which shows the results of the hearing test of a person that is suffering from mid-range or mid-frequency hearing loss. When a patient is diagnosed with Cookie Bite Hearing Loss prognosis, the pattern of their hearing thresholds looks like a ‘U’. There is a dent in the middle that looks like someone has taken a bite out of a cookie. Hence this hearing loss got this name. You can see the dent in the graph given below. And this dent indicates that a person is facing severe problems in hearing mid-range sounds.

So, a person with this hearing loss faces problems hearing sounds of mid-range or mid-frequency, which is from about 500 Hz to 2000 Hz. Humans can typically hear sounds from the range of 20 to 20,000 Hz. So, the sounds range from low frequency sounds to high-frequency sounds. And people with this hearing loss fail to hear the mid-frequency ones. A considerable part of human speech, and also music fall into this category. But they can still hear low-frequency and high-frequency sounds.

As you’ll still be able to hear many sounds despite having this hearing loss, you might succeed in figuring out what people around you are saying. That’s why many people fail to detect that they are suffering from hearing loss. But it can have severe consequences at times like you might hear someone slamming a door or playing a musical instrument, but won’t be able to hear someone speaking just beside that.

If the problem is not congenial, then cookie bite hearing loss gets developed slowly over quite some time, and people might notice this problem first in their 20s, but it gets severe when they are in their 30s or 40s. And people tend to not care about it until it gets unbearable, so it remains undetected and keeps worsening with time.

As they don’t get to hear sounds clearly, they need to raise the TV volume to understand what they are watch. It becomes tough to listen to music and understand environmental sounds.

And most importantly, their social life gets highly hampered as they struggle to keep up with conversations in crows or during social gatherings. Their life can get really frustrating as a consequence.

Reasons Behind Cookie Bite Hearing Loss

Cookie Bite Hearing loss is usually a genetic condition, so if someone in the family has a history of this hearing loss problem, future generations will be at risk of getting diagnosed by it. A person can be born with this problem, so that it can be congenital. Again, this problem can develop over time in a person due to the already existent genetic problem.

Apart from genetic reasons, some rare causes of cookie bite hearing loss problems are being developed. One such cause can be a rare type of tumor called “acoustic neuroma” or “vestibular schwannoma.” Suffering from it can lead a person to mid-frequency hearing loss.

How Can Cookie-Bite Hearing Loss Be Diagnosed?

The diagnosis process of Cookie Bite Hearing Loss involves an audiogram assessment that will reveal the particular patterns, which will point out that a person has this specific hearing loss. And as said earlier, the result of the cookie bite audiogram will look like the shape of a cookie bite. An Audiogram is a specific type of hearing test where the result of your hearing is shown on a graph. It will show the softest sounds you can hear during the test on that graph. Audiogram tests help determine what degree of hearing loss you have, and what frequency sound you can and can’t listen to.

If the hearing loss problem is hereditary, it might get discovered first when the child gets a hearing test. But if the hearing loss develops over time, it might take longer for someone to realize they have hearing loss, and the situation worsens with time. Sometimes the people you interact with might feel that you have hearing loss problems before you understand, as it is primarily a mild form of hearing loss.
