frequency of sound waves‚ was the sense tested during the course of this experiment. The mechanical processes involved in hearing include air vibrations that enter the outer ear and are converted to fluid vibration in the inner ear‚ which are then transduced to electrical signals sent to the brain for interpretation. (Connelly‚ 2014) Any time an object vibrates it creates sound waves that move the air molecules around it causing pressure changes at various speeds presenting as sound waves. The two

auditory messages; that is‚ messages transmitted through the medium of sound. Often‚ the steps of responding and remembering are also included. Hearing vs. Listening Listening and hearing are not the same. Hearing is the first stage of listening. Hearing occurs when your ears pick up sound waves which are then transported to your brain. This stage is your sense of hearing. Hearing is simply the act of perceiving sound by the ear. If you are not hearing-impaired‚ hearing simply happens

of them. Another piece composed by a member of the ARC orchestra by the name of Alia Martin is called Cogitation. I felt this piece could be in a movie. I really liked the parts the piano and flutes had in this. I loved how the piece grew bigger in sound and momentum in the end. I noticed that the violins played softly and there was a super high note coming from a flute in the orchestra which was beautiful. My most favorite performance of the night came from Betty Karamatova playing the piano. She

there for a while‚ since the 1960’s-why do some moths produce clicking sounds when bats attack them?” Most tiger moths emit ultrasonic clicking sounds to signal how toxic they are to bats. But Bertholdia trigona emits ten times as much sound‚ “indicating that it might be serving a different purpose entirely”. Aaron and colleagues collected the moths and put them in a cage with brown bats. They hypothesized that if the sounds were used for warning purposes the bats would ignore the clicks and eat

between the fingers of my left hand and a 60kg camouflaged bag on my back‚ I attempted to mentally stop and fight all my instincts which were telling me to run and retreat. The sound of gunfire made me want to turn around and face the noise coming from the other direction. As my aim and torch followed and rose up to the sound‚ it lit a dark alleyway invisible to the naked eye. The gunfire stopped as soon as it started so I took several deep breaths as I panned the small beam of light around the alleyway

A major campus issue that Charleston Southern University residents are dealing with is the levels of noise in the residence halls. This distraction affects students during their studies‚ sleep and quiet time. Charleston Southern residents were asked in a survey pertaining to the noise levels in the dorms unanimously answered that when studying‚ the noise levels are distracting. When the students were asked on a scale from one to ten‚ (one being that noise does not affect resident’s dorm life

the relationship between the speed of sound in air through the pulse-echo experiment and the measured air temperature. Hypothesis: I believe the measured air temperature will affect the speed of sound because sound waves are longitudinal waves composed of the alternating compressions and rarefactions in air. If the air temperature is below 0°C‚ then the speed of sound would be lower than 331.6 m/s and if the air temperature is above 0°C‚ then the speed of sound would be higher than 331.6 m/s. Materials:

because of all the combinations of all the parts. And how the music flows with the deep voices of the men in that choir. Another reason I like the song is just how all the parts perfectly put it together to show how challenge it sounds to sing this piece. The tone in this song sounds very deep and very dark because there are no high notes for the men. The amounts of dynamics to sing this song were a lot since they have to know your part and not miss a single note.How like the winter is my favorite song
