We saw in the last section that sound travels through the air as vibrations in air pressure. To hear sound, your ear has to do three basic things: Direct the sound waves into the hearing part of the ear Sense the fluctuations in air pressure Translate these fluctuations into an electri...
Music relaxes. Through the vibrations of sound waves, the music is a chemical catalyst that changes the endocrine and relaxes the mind. Listen to music. Be excited. Listen to the quiet music. Gloominess, listen to the gloominess of music, and then listen to the happy music. When feeling ...
Sound: Sound is produced and transmitted through the movement and displacement of air. The vibrations of soundwaves are mechanical waves that move as longitudinal waves, meaning the oscillation of the wave is parallel to the direction the wave travels. ...
Sound. When a drum is struck, the drumhead vibrates and the vibrations are transmitted through the air in the form ofsound waves. When they strike the ear, these waves produce the sensation of sound. Terms used in the study of sound ...
There is one crucially important difference between waves bumping over the sea and the sound waves that reach our ears. Sea waves travel as up-and-down vibrations: the water moves up and down (without really moving anywhere) as the energy in the wave travels forward. Waves like this are ...
Earthquakes may take place anywhere on the earths surface. During all earth quake, the vibrations make the earths surface tremble, and even crack open. Houses fall, people are lilled or injured and sometimes whole cities are destroyed.
t actually listen to music the way that hearing people do, but they can feel it. Sound is made up of vibrations, called sound waves, which hearing people can hear through their ears with the help of the brain. What’s really cool is that deaf people sense vibrations in the part of ...
One theory is that noise canceling technology can generate extremely low-frequency vibrations that stimulate balance receptors connected to our ears’ stereocilia, our hearing hair cells. What then happens is that these receptors falsely communicate to the brain that the head is moving despite one’...
When your eardrum vibrates, your brain interprets the vibrations as sound -- that's how you hear. Rapid changes in air pressure are the most common thing to vibrate your eardrum. An object produces sound when it vibrates in air (sound can also travel through liquids and solids, but air...
