What are the common causes of hearing loss?

Which of these common causes of hearing loss cause the most hearing loss?

I've heard (no pun intended) that wearing headphones with the volume turned up is a major reason. The length of time a person is exposed to loud noises is also a factor. The more exposure, the worse it is.  (+ info)

Do you get any earches when getting hearing loss from loud music?

What are the symptoms you see when getting hearing loss from loud music?

Ringing. The lovely sound of nerves dying.  (+ info)

What would cause injury-related hearing loss?

I want to know what events might lead to hearing loss. I'm not talking about blasting music or anything like that. I mean, like, perforation of the ear drum. What would cause that, short of someone jabbing a pointy object into an ear. Something accidental.

If you hit your head.  (+ info)

Anyone who had benefited from the latest technology on sensorineural hearing loss?

Anyone who had benefited from the latest technology on sensorineural hearing loss? Its something about sound vibration which helps people who have Sensorineural hearing loss hear naturally. I heard there was a 26 year old guy from Austria who took the treatment (surgery) and was wondering if I could get in touch with him? Any help on this would be highly appeciated!

What causes hearing loss in newborns?

is there something during pregnancy that could have cause hearing loss in the newborn...or what else could've cause hearing loss in a newborn?
what if none of the parents family have this problem what coul've been the cause?

simply being premature is a risk factor for newborns to have hearing loss. Also high or low (not sure which is more abnormal) billirubin counts (when baby has jaundice - yellow skin) is a risk factor for hearing loss. Genetics is a common factor as well. Even though the parents may not show hearing loss, hearing loss is commonly inherited through recessive genes. So both parents may each have 1 impaired gene for hearing loss, and pass it on to child. If child has 2 impaired genes they exhibit the trait (hearing loss), both parents only have 1 impaired gene so they don't show hearing loss, but they are carriers of the trait.  (+ info)

What does it mean when my head is throbbing & loss of hearing?

My head starts throbbing everytime I lay on my stomach. I feel a throbbing sensation in my head and I start to feel a slight loss in my hearing. Everything starts sounding really far away. am I okay?

Can ear infections cause loss of hearing?

I currently have an ear infection in my left ear and it has been causing me to not be able to hear as well. Will this loss of hearing be permanent? I am currently taking amoxicillin.

As kAudio has already stated you are most likely suffering for a conductive loss caused by the built up of fluid within your middle ear. This fluid acts as insulation stopping sounds from getting through to your ear.

Whether or not your hearing loss is permanent depends on the treatment you are receiving. Seeing as you are on antibiotics the likelihood is that your hearing will be back to normal in no time at all. What will happen is the fluid that is currently causing your hearing loss will be absorbed by your body.

Problems arise when people don't notice or don't care about an ear infection. If the infection is given time it can spread deeper down into your auditory system (cochlear) and cause a permanent hearing loss.

Seeing as I haven't actually conducted a proper exam on yourself and don't know any family/medical history it is hard to give you a 100% Yes or No answer.

I would suggest that if you are still concerned wait for the infection to clear up and then ask to be referred onto an Audiologist who can give your hearing proper testing.  (+ info)

Anatomy and Physiology: How is tympanic membrane involved in hearing loss.?

How is tympanic membrane involved in hearing loss and what is the reason for hearing loss and what are the typical treatments?

Sound waves travel along the external auditory meatus (passage from pinna to tympanic membrane) until they hit your eardrum and cause it to vibrate. As a result, your ossicles start moving. They, in turn, pass on vibrations to a thin layer of tissue at the entrance of your inner ear called the oval window. The movement of the oval window then sets off wave-like motions in the fluid in your cochlea.
Your organ of hearing, the spiral organ of Corti, runs through the inside of your cochlea. It consists of thousands of sensory hair cells, attached to a membrane. Tiny sensory hairs emerge from each sensory hair cell and pierce into a second, gel-like membrane above. Whenever the fluids in your cochlea are in motion, the first membrane vibrates and squashes the sensory hairs against the second membrane. The movement of your sensory hairs is then translated into nerve impulses, which travel along your cochlear nerve to your brain.
Conductive hearing loss
This is caused by anything that stops sound moving from your outer ear to your inner ear.
Perforated (pierced) eardrum, which can be caused by an untreated ear infection (chronic suppurative otitis media), head injury or a blow to the ear, or from poking something in your ear.

I have taken you literally and just gave stuff about the tympanic membrane - how it works, how it can cause deafness.

How to deal with low frequency hearing loss, are aids helpful?

My hearing test confirmed hearing loss across the board, but worst in the low frequencies. The audiologist is sending me to a ENT. I need to hear to work. Are hearing aids helpful, and which type/kind do you use?

They can fine tune them to your specific need and they help although sometimes in crowded places...for example a busy store they can be a pain. I just turn mine down or take them out then.  (+ info)

What type of tumor causes hearing loss?

40 yr old healthy male, no history of hearing loss himself or in his family, suddenly began to lose hearing in one ear. Hearing in that ear sounds like everything is under water. Doctor is testing to see if it's a tumor. What type of tumor would he be looking for - in the brain, in the ear? Is this common?

A review of the usual suspects:

A tumor in the nasopharynx, called Nasopharyngeal Carcinoma (NPC) often causes obstruction of the eustachian tube and a resultant buildup of fluid in the middle ear. This condition is more common in asians (especially from Hong Kong) but can affect any race. There are no other major risk factors for this illness. It is treatable with chemo and radiation, and survival depends on the stage of the disease. These tumors are detected by CT scan or MRI.

Another "tumor" that can cause conductive hearing loss is called a cholesteatoma. This is not actually a tumor but a collection of dead skin, oil and debris which has accumulated in the middle ear space (the space between the eardrum and the organ of hearing). This accumulation will continue to collect debris and can erode the bones of hearing and even the skull, causing hearing loss and eventually brain complications. Treatment for this condition is only surgical. These tumors are detected by CT scan and sometimes by clinical exam.

Another type of tumor is a vestibular or acustic neuroma. The two nerves (vestibular and acoustic) sit very close together, so which nerve it comes from is really just technical. These so-called benign tumors (because they do not metastasize to other parts of the body) can be very slow growing (just observe them) or can grow rapidly, causing pressure on the brain and eventually death. There are three treatment options for these: obeserve (do nothing), surgery, or radio-surgery (also called the gamma-knife). These tumors are detected with MRI.

The fourth type is a general category of other tumors...any other cancer of the head and neck can spread to the middle ear or inner ear. For example, melanoma of the scalp, or squamous cell carcinoma of the outer ear, etc. Another person mentioned endolymphatic sac...these are extremely rare, and a head and neck cancer surgeon at a major academic center might see one case in 40 years of practice (or none at all). Brain tumors can cause hearing loss, but not usually in one ear. Technically, acoustic or vestibular neuromas are not brain tumors as they are on the nerves, not IN the brain.

Hope this helps, best of luck. Most hearing loss is NOT from a tumor, but in an adult over 30, we must rule out tumors as a cause, because missing one could have devastating results for the patient.  (+ info)
