People with tinnitus should avoid silence—sound-rich environments distract the brain

Watch how your nervous system's efforts to process silence can contribute to tinnitus

Cochlear cells can be damaged in numerous ways, including aging or exposure to loud noise. If enough cells die, the auditory system can become less sensitive, prompting the brain to compensate by amplifying sound, which is likely to contribute to tinnitus.

One decibel of hearing loss increases tinnitus risk by 6% for older people

That's according to an analysis of more than 18,000 people published in BMC Medicine in 2023. The tinnitus risk is not just limited to older people: The research also concluded that one decibel of hearing loss increases the risk of developing tinnitus among young adults by 3 percent.

Tinnitus estimates vary, but may occur in 10%-15% of the population

This video discusses the mechanisms underlying tinnitus and explores the knowns and unknowns about the condition. Tinnitus most commonly occurs among those with hearing loss, suggesting that cochlear damage may be a factor.

Hear examples of what tinnitus can sound like to those suffering from it

This video, from a Scottish branch of the UK National Health Service, features different types of ringing, crackling, and other sounds that tinnitus sufferers experience. Individual responses to such phantom sounds may vary widely.

A new tinnitus therapy involves mild electric tongue shocks and sound exposures

Lenire, an FDA-approved bimodal neuromodulation treatment approach for tinnitus, aims to teach the brain to distract itself from tinnitus. It includes short-term daily sessions wearing a mouth device that delivers mild electrical pulses to the tongue while listening to different sounds. (Some users may experience a paywall.)

Pulsatile tinnitus is when you hear thumping synchronized with your heartbeat

This rare type of tinnitus, which sounds like rhythmic thumping or whooshing, is often linked to blood vessel conditions or high blood pressure. Lowering blood pressure through exercise and food choices can help reduce the severity of this condition.

There's no cure for tinnitus, but sometimes it goes away on its own

Though there's no cure, treatments and management approaches can significantly reduce symptoms and improve quality of life. Hearing aids, sound generators, and other steps can help some people with this condition. But sometimes tinnitus resolves within hours or days for reasons that remain unclear.

Certain medications can make tinnitus worse

Certain antidepressants, antimalarial medications, antibiotics, ibuprofen, and cancer drugs have been linked with the condition. At higher doses, particularly, it seems they can trigger or worsen tinnitus in some individuals.

The science behind why some noises have color names

Different noise colors (white, brown, pink, blue) have been proven to affect mood and focus. An audiologist explains that these sounds are named after specific light wave frequencies. While individual preferences vary, certain noises consistently impact sleep, stress reduction, cognitive performance, and problem-solving. The article highlights how these sounds can enhance productivity, relaxation, and even gaming experiences.

Tinnitus is derived from the Latin verb tinnire, meaning to ring

Read the entry in The Physical Dictionary by Stephen Blankaart, from 1693, where the word first appeared in English.

Read Charles Darwin's description of his tinnitus suffering

When he was 57 years old, Darwin wrote to a new doctor about his suffering from a variety of maladies, including "singing of ears", vomiting, recurring flatulence, vomiting, and more. He noted how he believed his stress contributed to these symptoms.

When common sounds become disturbing

Misophonia causes certain sounds to feel violating, triggering a "very visceral kind of experience" filled with extremely unpleasant emotions, including annoyance, anger, and disgust. A 2017 study found that people with misophonia have elevated activity in the brain's anterior insula—a region associated with interoception, emotional processing, and behavioral responses—when exposed to trigger sounds. Ongoing research suggests trigger sound context affects the severity and manifestation of the condition.

Noise pollution from humans and technology alters animal behavior

Animals may experience chronic stress and health issues due to noise pollution, which often interferes with their mating sounds. Due to traffic, nightingales sing louder on weekday mornings, and birds near airports start singing earlier to avoid upticks in takeoffs and landings.

The anechoic chamber at Bell Labs absorbs 99.999% of created sound

The space nearly eliminates sound wave reflection, allowing visitors to become aware of noises created by their own bodies, including their heartbeat and skeletal conduction. Experiments inside have contributed to the development of digital audio and phone touch tones.

Listen to why extensive ear rinsing can create problems

The clinician who hosts this podcast discusses how his patient developed swimmer's ear after he flooded his ears with water during his daily showers, ostensibly to clean them. The resulting itchy, painful ears were the result of removing protective earwax in the ear and also altering the typical pH of the ear.

An ear doctor with hearing loss seeks to help those with hearing loss enjoy music

Alex Chern, an ear doctor who has hearing loss himself, dreams of restoring the ability to experience "all the richness and the beauty of the sound of music" for patients—not just functional hearing. Hearing aids amplify sound waves and aren't designed to work well with music that may have varied pitch and volume. Chern is studying how hearing loss and engaging with music may affect cognitive decline.

What (and why) is ASMR?

ASMR podcasts and videos are appearing all over social media, so what exactly is it, and what does it do? This immersive article explains the phenomena of ASMR, which stands for autonomous sensory meridian response. ASMR is when certain sounds or...

How does the cocktail party effect work?

In the 1950s, British cognitive scientist Colin Cherry started to explore how we could focus our hearing on one single source, even in a noisy environment. This video animation explains the phenomenon known as the cocktail effect and how selective hearing works. Discover how our brain is on the lookout for important or personally relevant information, even as we are occupied in other discussions.

Pediatricians look for a list of behaviors to signal typical hearing development

These markers of typical hearing development among infants and toddlers include turning head to sound sources within the first five months of life, babbling by about 11 months, and trying to imitate simple words by 17 months of age.

Vertigo may be reduced by retraining your brain with visual fixation

In this video podcast neuroscientist Andrew Huberman describes one way to help alleviate dizziness and motion sickness symptoms. He suggests visual anchoring—fixating your vision on a point several feet away and moving closer to it, if possible, or fixating your vision on your extended finger and slowly moving it toward your nose and away again.

SAD uniquely affects people with attention-deficit hyperactivity disorder

Those with ADHD—chronic issues with attention and executive function—are primed for SAD. Many are disproportionately evening chronotypes (more awake in the evening), have a delayed sleep phase, and have low sensitivity to light in the morning. This podcast explores the overlap between these two groups.

Stress and the brain

While an acute stress response is a normal bodily function, the effects of chronic stress can be extremely damaging to the human body. This is particularly true with regard to the brain. This article explores the effects of stress on the human brain, including how chronic stress may lead to psychological conditions such as depression and memory loss.
