Ototoxic drugs can also cause subjective tinnitus, as they may cause hearing loss, or increase the damage done by exposure to loud noise. Those damages can occur even at doses that are not considered ototoxic. Over 260 medications have been reported to cause tinnitus as a side effect. In many cases, however, no underlying cause could be identified.
This well-designed study found that using CBT alongside elements of standard therapy can help patients with tinnitus of varying severity. However, the differences in outcomes between the two groups were quite small, and this technique can only help manage tinnitus rather than curing it, as some papers implied. Also, the patients in the study were followed for only 12 months, so it is unclear whether this approach can help in the longer term.
Many of us experience tinnitus every once in a while. If you’re exposed to extremely loud noise, or leave a noisy environment for a quiet one, you may notice a temporary buzzing or ringing in your ear. Maybe you’ve been near loud construction—like a jackhammer, or stepped out of a loud action movie or music concert to a quiet lobby or street. (Be aware: even a single exposure to very loud noise can do damage to your hearing, and increase your risk for tinnitus.)
Imagine you’re settling in for a night’s rest. In your quiet bedroom, you’re tune right into those tinnitus noises—and you can’t shake your focus on them. You start to wonder about how you’ll ever fall asleep with these sounds in your ears. You think about the rest you’re missing out on because you’re not already asleep, and you wonder how you’ll have the energy to make it through your day.
Tinnitus habituation therapies, such as tinnitus retraining therapy (TRT), involve using low level sounds in a graduated fashion to decrease the perception of tinnitus. This differs from use of masking devices such as described earlier. TRT involves a wearable device that an affected individual can adjust so that the level of sound emitting from the device is about equal to or matches the tinnitus sound. This may be called the “mixing point” because the sound from the device and the tinnitus sound begin to mix together. An affected individual must repeatedly adjust the device so that the sound is at or just below the mixing point. TRT is supported by counseling with a trained professional who can teach the individual the proper techniques to maximize the effectiveness of TRT. Eventually, by following this method, affected individuals no longer need the external sound generating device. Affected individuals will become accustomed to the tinnitus sound (habituation), except when they choose to focus on it. Even then the sound will not be bothersome or troubling. The theory is akin to a person’s ability to ignore sounds such as the hum of air conditioner, the refrigerator motor turning on, or raindrops falling on the roof when driving a car in the rain.
Most people who seek medical help for tinnitus experience it as subjective, constant sound like constant ringing in the ears or a buzzing sound in the ear, and most have some degree of hearing loss. Things that cause hearing loss (and tinnitus) include loud noise, medications that damage the nerves in the ear (ototoxic drugs), impacted earwax, middle ear problems (such as infections and vascular tumors), and aging. Tinnitus can also be a symptom of Meniere's disease, a disorder of the balance mechanism in the inner ear.
Treatment of the underlying primary disorder may help to improve or cure rhythmic tinnitus. For example, the treatment of blood vessel disorders (e.g. dural arteriovenous shunts) can include certain medications or surgery. A surgical procedure known as sinus wall reconstruction can successfully treat pulsatile tinnitus due to sigmoid sinus diverticulum and dehiscence. In fact, most individuals have experienced complete resolution of their tinnitus following this surgery. Surgery may also be necessary for rare cases of pulsatile tinnitus caused by a tumor.
Note however that tinnitus nearly always consists of fairly simple sounds -- for example, hearing someone talking that no one else can hear would not ordinarily be called tinnitus -- this would be called an auditory hallucination. Musical hallucinations in patients without psychiatric disturbance is most often described in older persons, years after hearing loss.
Technology and portable music devices also contribute to noise pollution, especially in younger people. Keep the volume of your phone, MP3 players or iPod on the lower end when listening to headphones, and don’t play very loud noises for long durations of time. To aid in tinnitus treatment, look out for changes in your ability to hear if you’re frequently exposed to loud noises, limit use of headphones or consider wearing earplugs.
In persons with pulsatile tinnitus, additional tests maybe proposed to study the blood vessels and to check the pressure inside the head. Gentle pressure on the neck can be performed to block the jugular vein but not the carotid artery. The Valsalva maneuver reduces venous return by increasing intrathoracic pressure. If there is a venous hum, this usually abates or improves markedly. If the pulsation is arterial, these tests have no effect.
Tinnitus is a common condition characterized by the perception or sensation of sound even though there is no identifiable external source for the sound. Tinnitus is often referred to as a “ringing in the ears.” However, the sounds associated with tinnitus have also been described as hissing, chirping, crickets, whooshing, or roaring sounds, amongst others, that can affect one or both ears. Tinnitus is generally broken down into two types: subjective and objective. Subjective tinnitus is very common and is defined as a sound that is audible only to the person with tinnitus. Subjective tinnitus is a purely electrochemical phenomenon and cannot be heard by an outside observer no matter how hard they try. Objective tinnitus, which is far less common, is defined as a sound that arises from an “objective” source, such as mechanical defect or a specific sound source, and can be heard by an outside observer under favorable conditions. The sounds from objective tinnitus occur somewhere within the body and reach the ears by conduction through various body tissues. Objective tinnitus is usually caused by disorders affecting the blood vessels (vascular system) or muscles (muscular system).
Paquette et al (2017) reported a prospective study of 166 patients who had brain surgery involving removal of the medial temporal lobe. The prevalence of tinnitus increased from approximately from 10 to 20% post surgery. This study did not include a control -- a natural question would be -- suppose a different part of the brain were removed. One would also think that drilling of the skull from any source might increase tinnitus. We are presently dubious that the medial temporal lobe suppresses tinnitus.
Tinnitus varies dramatically from person to person, so it is important that you visit an audiologist to learn more about your specific circumstances. Some of the causes result in permanent tinnitus and require treatment, while others induce temporary tinnitus that disappears on its own.

Some persons with severe TMJ (temporomandibular joint) arthritis have severe tinnitus. Generally these persons say that there is a "screeching" sound. This is another somatic tinnitus. TMJ is extremely common -- about 25% of the population. The exact prevalence of TMJ associated tinnitus is not established, but presumably it is rather high too. Having TMJ increases the odds that you have tinnitus too, by about a factor of 1.6-3.22 (Park and Moon, 2014; Lee et al, 2016). This is the a large risk factor for tinnitus, similar to the risk from hearing loss (see table above).
Tinnitus Retraining Therapy. Tinnitus Retraining Therapy (TRT) combines a wearable device that is individually programmed to mask the specific tonal frequency of that person’s tinnitus, with psychological therapy that teaches a patient to ignore the sounds his tinnitus is creating. I consider it the best of all of the above noise suppression techniques, as it is individually tailored for each person and involves support from a trained psychological therapist. It is also the most expensive and time consuming, but in my medical opinion, the most beneficial of all the noise suppression techniques listed above.
People with warning signs should see a doctor right away. People without warning signs in whom tinnitus recently developed should call their doctor, as should people with pulsatile tinnitus. Most people with tinnitus and no warning signs have had tinnitus for a long time. They can discuss the matter with their doctor and be seen at a mutually convenient time.
Tinnitus Control contains both a spray that is administered under the tongue three times a day and a gelatin capsule that is to be taken twice a day. Each package comes with a one month’s supply of the spray (1 fluid ounce) and capsules (60 capsules). Tinnitus Control is not currently available in local stores such as CVS, Walgreens and Rite Aid, but it is available directly from the manufacturer’s website at http://www.tinnituscontrol.com
Some patients choose to get involved in “tinnitus retraining,” which involves wearing a device in the ears that provides soothing music or noise, along with undergoing counseling. The goal is to help your body and brain learn to get accustomed to tinnitus noise, which reduces your negative reactions to unwanted sounds. Support and counseling during the process can be helpful for reducing anxiety. Researchers are now learning more about the benefits of coherent cognitive behavioral therapy interventions to help treat distress associated with tinnitus. (3)
Since most persons with tinnitus also have hearing loss, a pure tone hearing test resulting in an audiogram may help diagnose a cause, though some persons with tinnitus do not have hearing loss. An audiogram may also facilitate fitting of a hearing aid in those cases where hearing loss is significant. The pitch of tinnitus is often in the range of the hearing loss.
Another thing that tinnitus and sleep problems share? A tendency among people to brush them off, and try to “tough it out,” rather than addressing their conditions. It’s not worth it, to your health or your quality of life. If you’re having trouble sleeping and you have symptoms that sound like tinnitus, talk with your doctor about both, so you can sleep better—and feel better— soon.
Additional conditions that can cause pulsatile tinnitus include arterial bruit, abnormal passages or connections between the blood vessels of the outermost layer of the membrane (dura) that covers the brain and spinal cord (dural arteriovenous shunts), or conditions that cause increased pressure within the skull such as idiopathic intracranial hypertension (pseudotumor cerebri). Sigmoid sinus dehiscence may be associated with pseudotumor, but this connection has not been firmly established. It possible that cases of pulsatile tinnitus associated with pseudotumor may be caused by an undiagnosed SSWA. Head trauma, surgery, middle ear conductive hearing loss, and certain tumors can also cause pulsatile tinnitus. Obstructions within in the vessels that connect the heart and brain can also cause pulsatile tinnitus.
In some cases, a special audiologic device, which is worn like a hearing aid, may be prescribed. These devices, called masking agents, emit continuous, low-level white noises that suppress the tinnitus sounds. In some cases, a hearing aid may be recommended to help to suppress or diminish the sounds associated with tinnitus. A combination device (masker plus hearing aid) may also be used. Masking devices provide immediate relief by reducing or completely drowning out the tinnitus sound. However, when the masking device is removed, the tinnitus sound remains.
There are two types of tinnitus: subjective tinnitus and objective tinnitus. Tinnitus is usually subjective, meaning that there is no sound detectable by other means. Subjective tinnitus has also been called "tinnitus aurium", "non-auditory" or "non-vibratory" tinnitus. In very rare cases tinnitus can be heard by someone else using a stethoscope, and in less rare – but still uncommon – cases it can be measured as a spontaneous otoacoustic emission (SOAE) in the ear canal. In such cases it is objective tinnitus, also called "pseudo-tinnitus" or "vibratory" tinnitus.
Homeopathy, hypnosis, meditation and acupuncture are also thought to suppress tinnitus conditions. Studies have shown acupuncture can help relieve symptoms of tinnitus, but relief may not be seen until you have completed 10 to 15 sessions. Homeopathy, which uses plant, mineral and animal material in doses to help relieve ailments, can also be used as a treatment. Some remedies can be used to suppress loud roaring noises, echoing, dull humming and other tinnitus symptoms.
High-pitched ringing. Exposure to a very loud noise or a blow to the ear can cause a high-pitched ringing or buzzing that usually goes away after a few hours. However, if there's hearing loss as well, tinnitus may be permanent. Long-term noise exposure, age-related hearing loss or medications can cause a continuous, high-pitched ringing in both ears. Acoustic neuroma can cause continuous, high-pitched ringing in one ear.
Objective tinnitus is very rare. It can be heard by a doctor either using a stethoscope or by listening very closely to your ear. It occurs rarely and may due to involuntary muscle contractions or vascular deformities. The sound is often described as pulsating and may be heard in time with your heartbeat. Objective tinnitus usually has a determinable cause and disappears when treated by surgery or other medical intervention.
Tinnitus matching is helpful to identify the frequency and intensity of the tinnitus. This is a simple procedure in which the audiologist adjusts a sound until a patient indicates that it is the same as their tinnitus. Most patients match their tinnitus to the region of their hearing loss (Konig et al, 2006; Mahboubi et al, 2012). Unfortunately, the "gap detection test", does not work to confirm tinnitus in humabs (Boyen et al, 2015).
Lidocaine, a medication used for the treatment of certain types of abnormal heart rhythms, has been shown to relieve tinnitus for some people, but it must be given intravenously or into the middle ear to be effective. However, the benefits of lidocaine are almost always outweighed by the risks of the drug and it is therefore not recommended and not used for tinnitus.
