Hearing loss comes in many different flavors. It’s kind of like popsicles that way. Except, it’s not frozen… and, y’know, not nearly as tasty. On that note, it’s far less likely to give you an ice cream headache as well. So that’s a plus.

Types of Hearing Loss

Because there is a wide variety of hearing loss types, we’ve decided to set you up with a not-so brief look at the smorgasbord of hearing loss “genres” that you may or may not be living with.[1] Are you ready to be informed? (Don’t answer that. It was a rhetorical question.)

Hear’re seven types of hearing loss:


Sensorineural Hearing Loss

What a mouthful. This is the most common form of hearing loss experienced by the average Joe or Jane. It occurs when there’s been damage to the cells of the inner ear, or the auditory nerve itself. Typically, this can block or weaken the necessary transfer of nerve signals to the brain. These nerve signals are responsible for carrying info about the loudness and clarity of sounds to your lobes – the kind that’s located in between your ears, not on them.

When you have this category of hearing loss, noises can seem either too loud or too quiet; the speech of others may sound slurred; you may hear a strange ringing noise in your ear(s); you could have a hard time hearing the voices of women and children; and the art of good, old-fashioned conversation might be a real chore.

Sensorineural hearing loss is caused by aging, blood vessel and autoimmune diseases[2], heredity, injuries, ototoxic medications[3], illnesses, unusually loud noises, meningitis[4], mumps, scarlet fever, measles[5], and – everyone’s favorite – exposure to noise over time. Gotta love that one.

Conductive Hearing Loss

It may not be the most common form but trust us: conductive hearing loss definitely happens. This occurs when there’s an obstruction or damage to the outer/middle ear that blocks sound from moving back into the inner ear. It can be permanent or temporary. That depends on what caused it. Much like the other types of hearing loss you’ll grow to know and probably not love, it’s not what you would call “fun.”

Since the inner ear and auditory nerve is intact, anyone who experiences conductive hearing loss will find themselves straining to hear the pitch and loudness of sounds and voices, even though they may still pick up certain conversation points loud and clear.[6] They’ll also have an easier time hearing out of one ear than the other, feel pain or pressure in either ear, get flustered during telephone conversations, think that their own voice sounds loud or “different somehow,” and maybe even smell a not-so-sweet scent wafting out of their ear canal on certain occasions.[7] (Ew.)

Technically speaking, conductive hearing loss is caused by many different factors that affect the functionality of the outer and middle ears. Thus, it can be tricky to single out one root cause for this issue. But don’t let that stop you.

Mixed Hearing Loss

Just like its name suggests, the next entry on our list combines the worst parts of sensorineural and conductive hearing losses to make a mixed medley of aural discombobulation. Mixed hearing loss occurs when there’s damage in both the outer and the middle ear which significantly affects the capability of sound to travel back to their inner cousin properly.[8] In some instances, the cochlea, auditory nerve, or other inner ear structures within the inner ear suffer some degree of impairment as well. Ouch!

Cases of mixed hearing loss usually range from mild to severe, and just like the conductive kind, there’s a myriad of factors that cause it. A person’s symptoms can vary depending on how much of each hearing loss type their precious ears are affected by.

For instance, if an individual has more conductive hearing loss, they may find it difficult to understand speech and pick up sounds that are softer in volume than those pesky unwanted background noises that have become the bane of their existence. If they’re leaning towards the sensorineural hearing loss end of the spectrum, other people’s speech may be distorted. Even if they’re blaring Top 40 hits at a loud enough volume, the person in question may still struggle with comprehending what’s being said (or sung).

Age and factors like certain medication, genetic predisposition, and – you guessed it – continuous exposure to loud noises can contribute to this type.[9] Think of this one as the “greatest hits of hearing loss.”

Sudden Hearing Loss

Quick FactsOtherwise known as sudden sensorineural hearing loss (SSNHL), this category is defined as a loss of hearing greater than 30 decibels in three neighboring frequencies, occurring over a period of fewer than three days.[10]

SSNHL kind of creeps up on you – hence the “sudden” part. Maybe you’ll notice it upon awakening in the morning, maybe it’ll strike before you go to bed. Either way, it will rapidly develop over hours or days. Some people hear a “pop” sound in their ears when it starts to set in. Sometimes it’s immediate, sometimes it’s not. Truth be told, it’s hard to predict when and where SSNHL will strike next…it’s like a ninja in the night: silent but deadly.

Unilateral Hearing Loss

Unilateral hearing loss – or single-sided deafness (SSD, yet another acronym for you to learn) – is when only one ear loses its ability to hear (See a graphic record produced by audiometry below). This can be temporary or permanent depending on how it originated. SSD can be a symptom of viral infections, head injuries, and sometimes surgical procedures.[11] Oh my!

Besides impaired hearing on one side, SSD can cause difficulty determining which direction a sound is coming from. This can make walking across the street or driving to the gas station around the corner a nerve-wracking experience. We’re biting our nails just thinking about it!

High-Frequency Hearing Loss

Besides sensorineural, this is one of the most common forms of hearing loss ever. If someone can’t hear sounds between 2,000 Hz and 8,000 Hz, they have high-frequency hearing loss.[12]

Just like the other, um, ilk of hearing loss on this list, people who live with this condition struggle to keep up in everyday conversation – especially if the person they’re talking to has a high pitched voice. More often than not, they miss consonants in higher registers such as the letters F, H, and S. Speech often sounds slurred or muffled to them, especially when gabbing away with their friends or relatives on the phone.

What causes high-frequency hearing loss, anyway? (And can we start calling it HFHL for short? No? Okay then.) The three big culprits for this are aging, noise exposure, and certain medical conditions.[13] These are notorious for causing wear and tear on the inner ears’ sensory cells in the lower section of the cochlea. When these are damaged, your ability to translate noises into electrical impulses is severely hindered. And that’s not okay.


Commonly referred to as “ringing in the ears,” tinnitus is one of the most seriously annoying flavors – er, forms of hearing loss out there. It causes people to hear weird sounds that aren’t there like ringing, buzzing, whistling, clicking noises and more. Sometimes, tinnitus makes people hear music that’s not there, too. While we admit that would come in handy sometimes, it’s not healthy, so we don’t condone it.

Since millions of people experience tinnitus in the US alone, it’s become one of the most commonly reported health conditions in the nation. If you stop and think about how many people could be walking around out there listening to music that doesn’t technically exist, it’s a little creepy, no?

Tinnitus comes in two sub-genres: subjective and objective. Subjective tinnitus encompasses those sounds that only the afflicted can hear. Objective tinnitus is much rarer and includes head or ear noises that are audible to both the person who has it and the people around them.[14] Can you imagine if you got a Hall & Oates song stuck in your head and the rest of the world could hear it? Yikes. (We’re trying not to.)

Now that you’re all caught up on the different flavors – er, forms of hearing loss, what’s next?

Good question.

There are many misconceptions about hearing loss out there. Chances are, you may believe a few of them without even realizing it. For (your) ear’s sake, allow us to help you get a fresh perspective on three common myths about hearing loss you should stop believing.

    How the hell would I know what type of hearing loss I have? I have tinnitus (ringing) I have had a test done – graph.

    Quite frankly hearing aides are just a ripoff industry.

    Great explanation of type & degree of hearing loss. Good job Eargo!

    I tried Eargo hearing aidsfor about a month. At first, they seemed wonderful. Thenthe one in my right ear rotated as a result of my chewing during lunch. Apparently, the muscles involved in chewing flexed theareea where the devices were in my ear, causing the Eargo device to rotate and move deeper into my ear canal.

    I had to use tweezers to remove the errant device. I reinstalled the devices and continued with my life, still thinking that the devices were okay to use. But, the same thing happened again, and I had to ask my son to remove the rotated device because I was unable to do it myself, even with tweezers.

    I changed the tip of the errant device and continued to use them. Then, the same thing happened to the right ear’s device. Since the problem seemed to be resolved with the change to the larger tip in the right ear, I replaced the tip in the left ear as well, and the problem occurred again, even with the larger tips.

    This time, I removed both devices and haven’t used them since. As a result of those instances, the ends of my ear canals are still sore, even though it’s been several months since I last used the Eargo devices.

    After those experiences, I received a survey from Eargo. When I tried to complete it, and included my impression of Eargo, the questionaire began repeating the questions I had already responded to, in an endless loop. I then assumed that it was programmed to do that with negative responses, and I gave up trying to complete it. I haven’t used the Eargo devices since then, and I have moved on to other manufacturers, all of whom had negative things to say about Eargo.

    • Hi Don, we’re sorry to hear about the technical difficulties one of our surveys may have given you. I have requested our Client Care team reach out about the fit of your devices, and please feel free to dial us directly at 1-800-734-7603 so we can help support the issues you’re currently experiencing with your devices.

    I’m gonna try using Eargo….fingers crossed. the medical profession has sadly priced out the elderly. At a time in one’s life when money is short a “hearing aid” can cost thousands and competes with scant retirement budgets. So having worked for many years (and having served in the Army, using heavy artillery) I am now punished to age in a world of silence – hurtful and deeply sad.

    • Thank you for your service, Peter. Eargo was designed for adults with mild to moderate, high-frequency hearing loss and may not be appropriate for those experiencing more severe to profound loss. You can take our hearing screener at try.eargo.com, or call our team of personal hearing guides with any questions at 1-800-734-7603. Ch(ears)!

    • @Peter Weir: What Army? I was in the Air Force during Vietnam. Flying damaged my hearing and at one time I was told that since I wasn’t career military I could not get help with hearing aids. Two years ago I met a couple of guys who were Army and artillery. They told me things have changed with the VA and that I should try again. I did and am now getting a monthly disability plus now working on getting hearing aids with the help of the VA. You should contact your nearest VA office and go see them about hour hearing loss. They will arrange for a hearing exam.

      • Thank you for your service. We’re glad it seems you’ve found a hearing solution that meets your needs.

    article mentioned, adults living with mild to moderate, high-frequency hearing loss, what about tinnitus? Do you recommend I have a complete hearing test to get a full diagnosis

    • Individuals with tinnitus report hearing sensations of sounds such as ringing, hissing, buzzing, clicking or roaring without any external stimulus. Noises associated with tinnitus can vary in pitch with some loud enough to affect someone’s ability to focus. Moreover, the sounds may be present around the clock. Some of those experiencing tinnitus have reported some symptom relief through tinnitus maskers, the use of sound machines (which produce “white noise”) and, in some cases, hearing aids. Eargo was designed for adults with mild to moderate, high-frequency hearing loss. We cannot offer assurance our hearing aid will provide relief from tinnitus.

    • Thank you for letting us know, Jan. We’ll send a note to your personal hearing guide now. Please feel free to dial us directly at 1-800-734-7603.

  7. Does Medicare cover any costs of hearing devices such as Eargo?

    • We do not currently handle any insurance reimbursements as it helps help keep costs down for our clients. If your provider covers hearing aids, our audiologists will complete a superbill for you). Our personal hearing guides are all ears ? at 1-800-734-7603 for any questions.

  8. I suffer from tinnitus. I flew helicopters for over twenty years and used earplugs and my flight helmet while operating the machine. I have lost a great deal of hearing and the constant sometimes drives me nuts! Can or is hearing loss be hereditary? I tried so hard not to lose it.
