Summary:        Analog technology is a representation or analogy of some type of measurement. Analog technology usually consists of a dial. Some examples of analog technology are a clock and speedometer. Most of the time, when speaking of analog technology, we usually just mean something that is not digital. Digital technology is when information (measurements) are converted to numbers/digits and the numbers are stored or displayed. Sampling is when splitting occurs in regular intervals to convert analog to digital form. Sampling converts continuous signal to discrete signal then reconstruction turns discrete signal back to a continuous signal. Although, this new continuous signal created by digital technology, is not as exact as the original. This is due to how the accuracy of analog signal is more than digital because digital signal is finite.

Instrument Project | Luke Pires, Nathaniel Marino, Nicolas Reed, and Oscar Ponce Summary:        For this project, we had to create a completely new musical instrument with a full scale. With that, we also had to answer questions about out instrument and its function, use a program to measure it sound waves and answer questions about them, and play a song on our instrument. What I learned about percussion instruments (which is the type of instrument that we made) is that in order to create different notes, each thing that you hit (in order case, wooden sticks) needs to be a different size. This is due to how different sizes means that there is a different amount of space that the sound wave can travel (and vibrate molecules) in each note. I also learned that different materials create different tones. For example, when hitting a piece of wood and metal with the same amount of force, the two will create different sounds due to the difference of tone. Lastl...

Glass.harmonica.in.rome.arp  by  Arpingstone Summary:        Music is created through the vibrations of molecules when sound waves hit them. In order to create different sounds and have a full scale, you must be hitting things with different measurements. For example, to test this, you can hold an object such as a ruler, and grab on to a part of it that is somewhat close to an edge. Then, hit the side of the ruler that is smallest, and then hit the other side of the ruler. You will then notice a difference. This is due to how the amount of space that the sound wave can travel is different when changing the size of the object in which you hit. This is the exact way that some instruments function. Instruments such as the xylophone or glass harp (the one where the cups are filled with water). For the xylophone, the bars (the things that you hit) are all different sizes. For the glass harp, each glass is filled with a different amount of water, which...

Thoth08BigasDrumEvansChalmette  by  Infrogmation Summary:        Sound waves are longitudinal waves, meaning that the energy that they carry travels parallel to the wave. Sound waves are also mechanical waves, which means that they must travel through a medium such as a solid, liquid, or gas. With this, sound waves also travel through different mediums at different speeds. Due to how atoms and molecules are packed tightly together in a solid, sound waves are immediately transferred to the next molecule. Thus, in solids, sound waves can travel very quickly without losing energy. In a liquid, atoms and molecules are touching, but are not fastened to each other as strongly as a solid. In results, some of sound's energy is wasted when pushing the particles around (in a liquid) because they can slide past each other. This is due to how sound cannot travel across gaps between molecules, which can slow a sound wave down. In a gas, molecules are far apart, s...

“What effect can very loud music have on your hearing?” In your answer provide specific evidence, including organ names to help substantiate your claim.        The effect that very loud music can have on your hearing is that eventually, your hearing will begin to decline. As when consistently listening to very loud music, your hair cells inside of your inner ear will begin to become overworked and will die. This will causing leaking in your ear which is what creates the ringing sound in people's ears. When your hair cells begin to die, your hearing will become progressively worse as the hair cells are what allow your ear to interpret sound and so that the brain can understand the signal. Not only will your hair cells be affected, but so will the cochlea which will really damage your hearing. In closing, loud music will cause damage to the cochlea and more specifically the hair cells. This will result in ringing in your ears and your brain not being to understand soun...
