It is fascinating that the tiny bones in the middle ear appear to have evolved from gills that were no longer needed. Figure 2 shows the path that sound waves follow from the sound source where they ...

detailing how sound waves travel through air, the effects of temperature on sound speed, and the phenomenon of refraction. It describes the anatomy of the human ear, how sound is transmitted and ...

We can hear sounds because our ears turn sound vibrations from the air, into signals that are sent to our brain. We can’t hear all levels of sounds. Sound waves with very high frequencies are ...

Next and last stop, the middle ear. We are now looking at an actual eardrum. The eardrum's a thin piece of skin, and other tissues, stretched tight like a drum. When sound waves hit the eardrum ...

A team of researchers have developed "audible enclave" technology that creates pockets of sound that can be heard at a ...

Sound is a vibration that travels through air as a wave. These waves are created when an object moves back and forth, compressing and decompressing air molecules. The frequency of these vibrations ...

One of the more intriguing aspects of bird anatomy is their ears ... which protect the ear while allowing sound waves to pass through. Unlike mammals, birds do not have pinnae to help direct ...

The ability to send sound that becomes audible only at a specific location could transform entertainment, communication and spatial audio experiences. What is sound? Sound is a vibration that travels ...
