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

Hearing loss is linked with brain volume reductions

The brain looks different as a result of hearing loss, with reductions in brain volume overall and in specific areas, and these changes are hypothesized to impact cognition. Exactly why hearing loss alters cognition is an active area of research, but theories include that the elevated cognitive load of straining to hear affects brain power available for thinking and memory and that hearing loss leads to social isolation which boosts dementia risk.

Gene therapy is restoring hearing among kids with genetic deafness

Gene therapy for profound genetic deafness has been advancing in recent years, with multiple clinical trials enabling hearing at normal levels for the first time without hearing aids or cochlear implants. The therapies target hearing loss caused by mutations in the OTOF gene that codes for a protein called otoferlin. That protein normally plays a key role in relaying sound signals in synaptic transmission between the ear's inner hair cells and the auditory nerve.

See what loud noises do to inner ear hair cells

This animation illustrates how louder music can affect inner ear hair cells. Damage to these cells is generally considered permanent. Hearing protection like ear plugs can reduce the level of sound entering into the ear and help protect those cells.

Promoting the idea of hearing-at-all-costs in medical and education settings has created division in the deaf community and influenced decisions about learning sign language.

Brain implants can help colorblind people hear colors

Colorblind artist Neil Harbisson was born into a world of grey. In 2004, he had a chip installed connected to an external color frequency sensor. Once the sensor "reads" a color, it sends a signal to the chip and plays an associated sound both in and outside Harbisson's head.

Steps for buying your first hearing aids

Hearing aids have advanced in aesthetics, simplicity, and cost in recent years, but acquiring them can be daunting for first-timers. Experts suggest finding a high-quality audiologist and knowing your rights with medical services. They also recommend buying them sooner rather than later, as hearing issues can compound and grow more costly over time.

Can music alter your memories?

You’re familiar with music’s ability to transport you to a past experience, but new research suggests that music can even alter how you remember your past experiences. A team of psychology researchers and music experts recently published a study that demonstrates how music can help shift our emotional recollection of a memory. Read to learn more about the study’s findings and how it could influence therapy practices.

Notch music therapy may filter out some tinnitus frequencies

Researchers in Germany have developed a smartphone app-based therapy for individuals with tinnitus associated with hearing loss. Some people with tinnitus can use this Notch app with their hearing aids to at least partially block sound frequencies matching their tinnitus pitch—turning down the volume of their tinnitus.

More than 5% of the world's population has disabling hearing loss

Disabling hearing loss is defined as hearing loss greater than 35 decibels in the better hearing ear. (For context, that means the sound of leaves rustling, at roughly 30 decibels, would be inaudible even to your better-hearing ear.) The World Health Organization's data suggests that more than 5% of the world's population has this level of loss requiring rehabilitation, which amounts to 430 million people—including 34 million children.

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.

There's no cure for Ménière's disease, only medications to reduce frequency of attacks

Ménière's disease is an inner ear problem that can cause vertigo and hearing loss. Most of the time, Ménière's disease affects only one ear.

Most custom earmolds for in-ear hearing aids are made using 3D printing

The technology has also been utilized for behind-the-ear and receiver-in-canal hearing aids, allowing for the creation of structures tailored to the patient's anatomy for enhanced effectiveness. 3D printing has also been used to print retinal eye cells and custom eyeglass frames.

Big Ocean is breaking barriers as the world's first deaf K-pop boy band

The three-person boy band—whose members have different levels of hearing loss—use light systems, vibrations, and a mix of Korean and American Sign Languages, as well as International Sign (which isn't a whole language), to communicate and keep their dance routines in sync. In this interview, a band member with partial hearing describes their challenges.

What to listen to if you want to focus

Have you ever put your headphones in, turned on your favorite playlist, and tuned out the rest of the world? That’s the power of music. It can improve your mood, reduce stress, and enhance focus. But what kind of music is best when working or studying? Check out this list for some suggestions.

Greek poetry was usually created with the intention that the words would be sung along with music. Evidence and reconstructions of ancient melodies and instruments mean researchers and musicians of today can play music in which the final notes have long since faded.

Acoustic Vehicle Alerting Systems provide motor sounds in electric vehicles

Since 2019, various global standards have set requirements for these systems, which seek to mimic combustion-engine sounds by meeting specific sonic criteria, including sound pressure, frequency, and pitch. Sound engineers design these systems to meet these requirements, ensuring that passers-by, particularly the blind and visually impaired, can detect the presence of a vehicle.

How radio works

Antennae tune a radio to a particular frequency (determined by the listener on their radio's dial) while tuning out all the other stations being broadcast. AM, short for amplitude modulation, and FM, short for frequency modulation, decode audio signals differently, leading to differences in sound quality and the distance a station can travel.
