Hearing loss is categorized by severity, type, and configuration. Furthermore, a hearing loss may exist in only one ear (unilateral) or in both ears (bilateral). Hearing loss can be temporary or permanent, sudden or progressive. The severity of a hearing loss is ranked according to ranges of nominal thresholds in which a sound must be so it can be detected by an individual. It is measured in decibels of hearing loss, or dB HL. There are three main types of hearing loss: conductive hearing loss, sensorineural hearing loss, and mixed hearing loss.[15] An additional problem which is increasingly recognised is auditory processing disorder which is not a hearing loss as such but a difficulty perceiving sound. The shape of an audiogram shows the relative configuration of the hearing loss, such as a Carhart notch for otosclerosis, 'noise' notch for noise-induced damage, high frequency rolloff for presbycusis, or a flat audiogram for conductive hearing loss. In conjunction with speech audiometry, it may indicate central auditory processing disorder, or the presence of a schwannoma or other tumor.

Rapid referral for a comprehensive audiological assessment provides reassurance, and can help control an escalation of symptoms and limit the development of hyperacusis. History taking should document immediate and persistent symptoms since the acoustic incident exposure; prior acoustic incident exposures; and prior otological and psychological history. Significant malingering is rare in ASD clients, in my experience. Most clients are bewildered, frightened or angered by their symptoms and desperate to recover.
Some people also experience a lot of pressure and pain in the ears. There can also be headache, muscle and joint pain along the neck, and stiffness of the limbs along with a tingling sensation on the top of the head, arms, and legs. In rare cases, there may be some emotional or psychological problems such as anxiety and panic attacks. The person may feel depressed, tired and frustrated. He/she may lose interest in routine activities. These, however, are common psychological side effects of general ill-health.
Typically, people describe acoustic shock as feeling like they have been stabbed or electrocuted in the ear. The symptoms are involuntary, unpleasant and frightening; they can range from mild to severe; and be of short, temporary duration or persistent. If symptoms persist, a range of emotional reactions including trauma, anxiety and depression can develop.
Itching (pruritis) of the ear due to otitis externa is caused primarily by irritation with foreign objects like a cotton ear swabs, hair pins, pens/pencils and matchsticks. The accumulation of water, dust or dirt, sand and other foreign particles that can enter the ear may also be responsible. An allergic reaction may occur or an infection may arise. Certain itchy skin conditions like psoriasis and eczema may also be responsible for itching of the ear canal.
Some people experience a sound that beats in time with their pulse, known as pulsatile tinnitus or vascular tinnitus.[39] Pulsatile tinnitus is usually objective in nature, resulting from altered blood flow, increased blood turbulence near the ear, such as from atherosclerosis or venous hum,[40] but it can also arise as a subjective phenomenon from an increased awareness of blood flow in the ear.[39] Rarely, pulsatile tinnitus may be a symptom of potentially life-threatening conditions such as carotid artery aneurysm[41] or carotid artery dissection.[42] Pulsatile tinnitus may also indicate vasculitis, or more specifically, giant cell arteritis. Pulsatile tinnitus may also be an indication of idiopathic intracranial hypertension.[43] Pulsatile tinnitus can be a symptom of intracranial vascular abnormalities and should be evaluated for irregular noises of blood flow (bruits).[44]
Boosting your immune system may also stop ringing in your ears. This will help to protect you from infections and diseases that may increase the level of unwanted sound. Also, an improvement in your health can mean an improvement in your tinnitus. Have a healthy lifestyle, which especially includes a healthy diet, proper and regular exercise, and enough sleep at night.
When asked if the 80-year-old mark for qualification was a bit on the high side, and also about “Mrs. Eighty,” Dr. Ramasamy was quick to respond: “That’s not true; we live in Miami, where sex is of paramount importance to all men regardless of their age. We have had irate patients who are 84 and 85 years of age call us asking why the cutoff is 80, and I feel bad for them, but that’s in our clinical trial criteria. Maybe in the next trial, we could design it to go to 90.”
Middle ear fluid or infection—The middle ear space normally contains air, but it can become inflamed and fluid filled (otitis media). An active infection in this area with fluid is called acute otitis media and is often painful and can cause fever. Serous otitis media is fluid in middle ear without active infection. Both conditions are common in children. Chronic otitis media is associated with lasting ear discharge and/or damage to the ear drum or middle ear bones (ossicles).
Plagued by an unidentified ringing, buzzing, whooshing or other mysterious noise in your ears? It sounds like you may be suffering from tinnitus. Tinnitus is the name for hearing noises that are not caused by an outside source and while it can be extremely frustrating, the good news is it's extremely rare that tinnitus is related to anything more serious.
Assessment of psychological processes related to tinnitus involves measurement of tinnitus severity and distress (i.e., nature and extent of tinnitus-related problems), measured subjectively by validated self-report tinnitus questionnaires.[16] These questionnaires measure the degree of psychological distress and handicap associated with tinnitus, including effects on hearing, lifestyle, health and emotional functioning.[63][64][65] A broader assessment of general functioning, such as levels of anxiety, depression, stress, life stressors and sleep difficulties, is also important in the assessment of tinnitus due to higher risk of negative well-being across these areas, which may be affected by or exacerbate the tinnitus symptoms for the individual.[66] Overall, current assessment measures are aimed to identify individual levels of distress and interference, coping responses and perceptions of tinnitus in order to inform treatment and monitor progress. However, wide variability, inconsistencies and lack of consensus regarding assessment methodology are evidenced in the literature, limiting comparison of treatment effectiveness.[67] Developed to guide diagnosis or classify severity, most tinnitus questionnaires have been shown to be treatment-sensitive outcome measures.[68]

I was a few feet away from a coworker when she reported a very painful blast of sound through her headset recently. She was crying and shakey, and the ear I could see, as well as a couple inches of the skin surrounding the ear, were very reddened. This was a few minutes post injury and she said it still hurt very much. Both our Human Resources Department and Information Technology seemed to have no idea what had happened to cause the injury. How could they not know abt. acoustic shock injury by now? Since a couple years after starting working at my call center, I have had ridiculously hypersensitive hearing. Everything in my environment seems too loud and I’m also ridiculously irritable most of the time, but especially when there’s any noise in my environment like small children make, or traffic. It’s like my nervous system is all revved up most of the time for no particular reason. Now I know why.

The Institute for Occupational Safety and Health of the German Social Accident Insurance has created a hearing impairment calculator based on the ISO 1999 model for studying threshold shift in relatively homogeneous groups of people, such as workers with the same type of job. The ISO 1999 model estimates how much hearing impairment in a group can be ascribed to age and noise exposure. The result is calculated via an algebraic equation that uses the A-weighted noise exposure level, how many years the people were exposed to this noise, how old the people are, and their sex. The model’s estimations are only useful for people without hearing loss due to non-job related exposure and can be used for prevention activities.[98]
Atherosclerosis. With age and buildup of cholesterol and other deposits, major blood vessels close to your middle and inner ear lose some of their elasticity — the ability to flex or expand slightly with each heartbeat. That causes blood flow to become more forceful, making it easier for your ear to detect the beats. You can generally hear this type of tinnitus in both ears.
▶ For most inner ear problems, a sodium-restricted, caffeine-free diet is recommended. Caffeine is a central nervous system stimulant and its intake makes the symptoms of inner ear disorder (especially headache and dizziness) appear more pronounced. Hence, it is advisable to reduce the intake of caffeine as much as possible till the condition is completely treated. Excess sugar in the diet also triggers dizziness.
Noise-induced hearing loss (NIHL) typically manifests as elevated hearing thresholds (i.e. less sensitivity or muting). Noise exposure is the cause of approximately half of all cases of hearing loss, causing some degree of problems in 5% of the population globally.[50] The majority of hearing loss is not due to age, but due to noise exposure.[51] Various governmental, industry and standards organizations set noise standards.[52] Many people are unaware of the presence of environmental sound at damaging levels, or of the level at which sound becomes harmful. Common sources of damaging noise levels include car stereos, children's toys, motor vehicles, crowds, lawn and maintenance equipment, power tools, gun use, musical instruments, and even hair dryers. Noise damage is cumulative; all sources of damage must be considered to assess risk. In the US, 12.5% of children aged 6–19 years have permanent hearing damage from excessive noise exposure.[53] The World Health Organization estimates that half of those between 12 and 35 are at risk from using personal audio devices that are too loud.[11] Hearing loss in adolescents may be caused by loud noise from toys, music by headphones, and concerts or events.[54]
In cases of infection, antibiotics or antifungal medications are an option. Some conditions are amenable to surgical intervention such as middle ear fluid, cholesteatoma, and otosclerosis. If conductive hearing loss is due to head trauma, surgical repair is an option.[5] If absence or deformation of ear structures cannot be corrected, or if the patient declines surgery, hearing aids which amplify sounds are a possible treatment option.[2] Bone conduction hearing aids are useful as these deliver sound directly, through bone, to the cochlea or organ of hearing bypassing the pathology. These can be on a soft or hard headband or can be inserted surgically, a bone anchored hearing aid, of which there are several types. Conventional air conduction hearing aids can also be used.
I wanted to become a surgeon from a very young age and eventually chose ENT surgery for various reasons. Firstly, I had a great mentor when I was a student who was an ENT surgeon. He engaged with me and encouraged me to do research with him which was eventually published. Secondly, ENT surgery is one of only a handful of surgical specialties who see and treat patients of all ages from very small babies to the elderly so the work is very varied.
Vertigo is the subjective sensation of the surroundings moving or spinning. It is a symptom of inner ear disease (peripheral) or disorders associated with the brain (central). The cause of many cases of vertigo are unknown (idiopathic) although peripheral vertigo may be related to infection, trauma or chemical irritation of the semicircular canals. Central vertigo may be seen in conditions like multiple sclerosis or strokes.
Tinnitus is sometimes called ‘the sound of silence' because most people, if they are seated in a completely quiet soundproofed room, will hear a type of rushing or hissing sound. Usually this sound is masked by everyday environmental noise. It is when this noise becomes intrusive that it can become irritating and is known as ‘tinnitus'. The more anxious the sufferer gets the worse the tinnitus becomes.

Hyperacusis is an increased sensitivity to sound. If you find that everyday or ordinary sounds are uncomfortable, you may have hyperacusis. Whilst it might seem natural to want to block out as much sound as possible, avoiding sound can actually make hyperacusis worse. Talk to your GP about this and ask for a referral to either an ENT Surgeon or Audiovestibular Physician who will be able to suggest management options – often, using sound (in a very controlled way) can improve hyperacusis.
Look into biofeedback therapy for your tinnitus. If you are depressed, stressed, or fatigued, then you may be more susceptible to normal head sounds. Look into biofeedback therapy from a counselor who can help you to tune into the feelings and situations that cause or worsen your tinnitus. This may help you to stop tinnitus when it starts and prevent it from coming back.[2]

Pulsatile tinnitus is a rare type of tinnitus that sounds like a rhythmic pulsing in the ear, usually in time with your heartbeat. A doctor may be able to hear it by pressing a stethoscope against your neck or by placing a tiny microphone inside the ear canal. This kind of tinnitus is most often caused by problems with blood flow in the head or neck. Pulsatile tinnitus also may be caused by brain tumors or abnormalities in brain structure.
Noise exposure is the most significant risk factor for noise-induced hearing loss that can be prevented. Different programs exist for specific populations such as school-age children, adolescents and workers.[87] Education regarding noise exposure increases the use of hearing protectors.[88] The use of antioxidants is being studied for the prevention of noise-induced hearing loss, particularly for scenarios in which noise exposure cannot be reduced, such as during military operations.[89]
Disorders responsible for hearing loss include auditory neuropathy,[57][58] Down syndrome,[59] Charcot–Marie–Tooth disease variant 1E,[60] autoimmune disease, multiple sclerosis, meningitis, cholesteatoma, otosclerosis, perilymph fistula, Ménière's disease, recurring ear infections, strokes, superior semicircular canal dehiscence, Pierre Robin, Treacher-Collins, Retinitis Pigmentosa, Pedreds, and Turners syndrome, syphilis, vestibular schwannoma, and viral infections such as measles, mumps, congenital rubella (also called German measles) syndrome, several varieties of herpes viruses,[61] HIV/AIDS,[62] and West Nile virus.
Spontaneous otoacoustic emissions (SOAEs), which are faint high-frequency tones that are produced in the inner ear and can be measured in the ear canal with a sensitive microphone, may also cause tinnitus.[6] About 8% of those with SOAEs and tinnitus have SOAE-linked tinnitus,[need quotation to verify] while the percentage of all cases of tinnitus caused by SOAEs is estimated at about 4%.[6]
