A frog living near the noisy springs in central China was found by researchers from the University of Illinois and the University of California to have the ability to tune its ears to hear only certain sound frequencies, as opposed to hearing all the sounds in the acoustic spectrum at the same time, as humans do. Pre... |

The results of an Australian governmental study show that people listening to music at high volumes, especially those who use earphones and headphones, are subjected to a higher risk of developing permanent hearing problems. The study shows that about two thirds of the population of Australia is affected to some exte... |

Mammals are supposed to have bloomed after the disappearance of the dinosaur, 65 million-year ago. During the dinosaur times, all mammals must have been shrew-like creatures hiding during the day and only getting out in the night to hunt for insects. But a fossil jawbone of Teinolophos, an 122 million-year old fossil... |

Many terrestrial and aquatic species can hear lower and higher frequencies than those detected by humans (infrasound, respectively ultrasounds). Frequency is crucial in defining a sound. Now, an Israeli team sustained by UCLA researchers has showed for the first time, in a research published in the journal "Nature," ... |

In the middle of a crowded party, you approach and manage to talk with your preferred "target", with all the thundering background noise. This has been a mystery: how can we ignore background noise to focus just on the voice of our interlocutor. It has been believed that the brain differentiates sound sources by ass... |

Forget the rubber bullets and water jets. The weapon of the future for controlling the mob will employ sounds. Or you may use it against the little monsters of the Halloween or an annoying neighbor. The handheld sonic gun, called Sonic Devestator, can emit intense ultrasonic charges capable of causing intense pain an... |

You may have heard about many freak records (and the Guinness Book of World Records is full of them) and now you can add another one: Radhakant Bajpai, a grocer from the city of Kanpur, in the state of Uttar Pradesh, northern India, has the world's hairiest ears. Bajpai's ear tufts were already 13.2 cm (5.2... |

A healthy ear reacts to the sounds it receives, emitting soft sounds in response. These sounds can be detected by sensitive microphones, which enable doctors check newborns' hearing, as a deaf ear doesn't reflect the sounds. A new study published in the "Proceedings of the National Academy of Sciences" and... |

The classical number of cobra dancing is a spoof. Even if the snakes would be tamed so that they would dance to the sound of the music, they could not do it. They just follow the tamer's continuous movements of the arms and knees, while he's playing a wind instrument, as snakes don't even hear the musi... |

There must have been something about our hearing that enabled us to differentiate speech and music from other sounds. The human ear can detect sound frequencies of 16Hz to 20 kHz, no matter if tones were high or low, near or far. But our ears are simple compared to the remarkable ability of single brain neurons to ma... |

1.Movement or chocking of the objects produce sounds. A sound is the vibration of elastic waves through different environments (solid, liquid, gaseous), with a frequency between 16 Hz to 20,000 Hz (20 kHz) (which is detected by the human ear). 2.Human ear has three parts: external, median and internal. The external e... |

In many cases what you see is not what you hear and what you hear is not what you see. This is how many tricks work, like ventriloquists making people believe the dummy is speaking. Now, a monkey brain has revealed us how this can happen: due to a brain nucleus involved in sight and sound simultaneously."The prevaili... |

You may pump Viagra into your body, for the sake of having wild sex, but the Kenny G track will be heard just by the neighbors. The first report of Viagra-hear loss was reported by two researchers at an Air Force hospital in Bangalore, India, when a 44-year-old man experienced a sudden hear loss following 15 days of ... |

We are addicted to the bone to mobile phones, but a new research comes with a warning for our technological world: the regular use of a mobile phone over more than a decade can raise the risk of cancer. The long-term users were found to have a double chance of developing a malignant tumor on the side of the brain wh... |

This is the second technological addiction of today's people, after the Internet. But experts warn that using a mobile phone for over an hour daily could induce hearing damage. Research reveals that persons who regularly employ their mobile for over an hour a day experience hearing impairment, and it is especial... |

The ear of a fish does not capture the sounds in the air and the first backboned species that conquered the land were largely deaf, lacking the tiny bones that transmitted the airborne sounds to the inner ear. Evolved hearing was believed to have evolved just before the emergence of dinosaurs, about 200 million years... |

Humans can hear sounds between 20 Hz and 20 kHz. Bats and dolphins go much further: they can hear sounds over 20 kHz (ultrasounds), while dogs and elephants hear sounds under 20 Hz (infrasounds). For 30 years, researchers stated various hypotheses on how specialized cells in the mammals' inner ear amplify sounds... |

You could be a little Napoleon that can listen to a phone message while at the same time talking with a friend and understand what both are saying and perhaps writing something at your desk. In this case, you have a good genetic package, as signaled by a team at the National Institute on Deafness and Other Communicat... |

Our food is turning more and more artificial, the way our environment is and so does our body. A team at Georgetown University Medical Center and the National Institutes of Health (NIH) has managed, for the first time, to develop a "bionic" ear that gave back hearing to a patient with von Hippel-Lindau disease. The b... |

First mammals roamed with the dinosaurs during the Mesozoic Era. Now, an American-Chinese team has dug a new species of ancestral mammal, 125 million years old, that represents a missing link, providing for the first time fossil evidence on how mammals developed their middle ear, one of the most distinctive traits of... |

OK, the subtitle definitely sounds funny but it reflects the truth: Re Go Media have released an ear-training software which is now at hand. The Audio Wizard Pro Ear Trainer is a program designed to improve the way you both hear and detect certain frequencies and this is definitely one good asset for a sound technici... |
