It has always been an interesting topic to figure out how our brains not only receive but also process information amid the booming noise in parties. With the booze, the blinking lights, and the ridiculously loud music, it is a wonder how our brains keep up with conversations with too much to process.
Jumping spiders could respond to sounds from three to five meters away
There is more to determining an animal's intelligence than brain size. A new study from the University of Toronto found an ancient rodent species had a large brain that was even heftier than those of some primitive primates of the same era, but it wasn't necessarily "smarter."
Mammals have evolved much more sensitive hearing than their reptile-like ancestors thanks to three super tiny bones tucked away in the auditory canal. But researchers are still unsure how the mammalian middle ear evolve. Now the University of Queensland (UQ), is shedding some light on the matter, challenging current beliefs and calling for further fossil evidence.
Hominin fossils examined from South Africa suggest early humans and chimpanzees had similar hearing patterns, with some slight differences in the direction of humans. This is a preferable auditory system for people living in the savanna and communicating within a short range.
Scientists are still working to figure out how various noise pollution affects marine animals, and now new research suggests that the building of wind turbines may be putting the hearing of UK harbor seals at risk.
New research has revealed that baleen whales, a group that makes up some of the largest animals on Earth, hear their surroundings and one another in a rather unique way. Their bones, it appears, can resonate with low frequencies, capturing sound and directing it to their ears, enabling supersensitive hearing that can stretch for miles.
Researcher have determined how birds accurately determine the direction of a sound, even when they do not have the complex external ear structures that most mammals, humans included, boast.
Ever wonder what it takes to be a dog whisperer? Most will tell you that the first step is understanding what a dog hears when you speak to it. Now a team of experts are trying to break this down to a science, measuring how dogs process the different components of human speech.
Went to one too many Guns N' Roses concerts in your youth? Having trouble hearing your friends and family as you age? Researchers are suggesting that you don't necessarily need to get a hearing aid. Experts may be able to simply restore your hearing, good as new.
The remarkably sensitive hearing of parasitic flies helps them find their prey even in poorly lit environments. Now researchers think this same super-hearing could one day help deaf humans hear, as its unique mechanisms have inspired the next generation of hearing aids.
It is already well known that a great deal of health problems arise from smoking tobacco. Now researchers have discovered that cigarette smoking and second hand smoke can also lead to hearing loss, although why this occurs remains unclear.
