Say What? Mice that Resist Hearing Loss Could Help Aging EarsErica Westly
All around the animal kingdom,there are sounds that we can hardly pick up and translate.Elephants,for example,talk with each other using infrasonic sound(次声波)- far below our human hearing range. Coral in the ocean also sends sound waves to attract baby coral to safer areas to grow.This...

If it’s in the range of human hearing, we should be able to hear it. The problem, however, is that there’s a finite number of instruments in the world. The objects we have for realizing sound potential are inherently limited. more Dec 4, 2009 Nate Greenberg AEM033 Freshwater ...

It would be difficult to account for the large range of sound levels in human hearing using a linear scale, so the decibel is a logarithmic unit. Some people describe one decibel as the "just noticeable difference" of intensity between two sounds, but this only holds for quieter sounds. Th...
Family members ask you if your hearing is okay. You cup your hand behind one of your ears when you listen. You need to have the radio or television louder than usual. You need to lean forward or turn your head to be able to hear. You have ringing or buzzing in your ears, or you...
The inner ear is not involved withhearing. It is composed of three semicircular canals, positioned at right angles to each other, that are lined with sensitive nerve cells, which act like a gyroscope for the body. This arrangement of the semicircular canals, in combination with the hair cells...

This logarithmic scale of the sound intensity ratio adjusts to the intensity perceived by the human ear. Since we can hear a very wide range of sound intensities, the limit of audibility -- 10-12 watt/m2 -- is conventionalized as 0 decibels. Thus, there are sounds lower than that, but...
