... in central China can tune its ears to different sound frequencies, much like the tuner on a radio can ... call, a male will leap directly toward the sound with an error of less than 1 percent, a feat ...

... -like force. Researchers can control the rate of these oscillations by exposing the droplets to different sound frequencies. By passing light through these droplets, the device is transformed into a ...

... of anthropogenic sound on marine mammals. Human activities produce a range of underwater sound frequencies that can interfere with marine mammal functions important for their survival. Use of sound ...

... discovered for smells, in part because odor molecules are much more difficult to pin down than sound frequencies. To create their map, the scientists began with 250 odorants and generated, for each, ...

... test, called pure tone audiometry, measures hearing sensitivity across a range of sound frequencies. "Using the data from the hearing tests, we measured hearing impairment in eight different ways. ...

... we analyse two syllables that sound the same with a machine that measures sound frequencies, we will see that they are not exactly the same; so, how does the baby know it is hearing the same syllable ...

... , less well to nearby frequencies, and poorly to distant sound frequencies. The range of effective frequencies can be measured as the "tuning width." Cells with similar tuning are found together, ...

... event, echolocating bats would be strong medal contenders. Their ears are tuned to higher sound frequencies than those of any other mammals because they need to listen to the returning echoes of ...

... into vibrations that allow the user to distinguish between vibratory patterns associated with different sound frequencies. The MIT researchers are testing devices that have at least two vibration ...

... why varying lengths of stereocilia predict which sound frequencies are heard most easily by a variety of animals ... mammals have "inner hair cells" that sense sound passively and active "outer hair cells ...
