Tractors. Pneumatic percussion drills. Jackhammers. Loud music. According to the Centers for Disease Control (CDC,) every day up to 4 million people are subjected to damaging noise as a routine part of their jobs. Unfortunately that translates to a lot of people at a high risk of noise-induced hearing loss (NIHL). New research, however, is shedding light on exactly what physiological changes occur during NIHL, specifically to the hearing parts of the brain, in an effort to create new prevention and treatment options.

Myriad sounds have been found to cause seizures in cats, according to research published in the Journal of Feline Medicine and Surgery. Feline audiogenic reflex seizures are triggered by such sounds as the tapping of spoons on bowls and glasses, and crinkling tinfoil, paper or plastic bags. The seizures are most common in older cats between 10 and 19 years of age
The lifecycle of yellow Ormia flies, whose larvae burrow into crickets and eat them alive, has inspired the design of a new hearing aid able to help wearers identify the location of sounds.
About one in five people experience tinnitus, the perception of a sound -- often described as ringing -- that isn't really there. Now, researchers have taken advantage of a rare opportunity to record directly from the brain of a person with tinnitus in order to find the brain networks responsible.
In a new genome-wide association study, an international team of neuroscientists has found evidence that some people may be more genetically susceptible to noise-induced hearing loss than others.
Government of Nova Scotia introduces new legislation requiring audiologists to register with a new regulated body.
Researchers have shed new light on synesthesia -- the effect of hearing colors, seeing sounds and other cross-sensory phenomena.
A large study looked at 211 undergraduate students and found that about 1 in 5 experienced exploding head syndrome -- hearing abrupt loud noises when waking up or going to sleep -- at least once and 37% reported having isolated sleep paralysis. The findings, published in the Journal of Sleep Research, also revealed a correlation between the condition and fear.
Does hearing about a company's charitable donations raise your opinion of their products? According to a new study, corporate social responsibility leads consumers to believe products are better quality.
Mammals are good at figuring out which direction a sound is coming from, whether it's a predator breathing down our necks or a baby crying for its mother. But how we judge how far away that sound is was a mystery until now. Researchers report that echoes and fluctuations in volume are the cues we use to figure the distance between us and the source of a noise.
