Blowing Bottle Tops: Making Music with Glass Bottles

A sound wave is a disturbance that repeats regularly in space and time and that transmits energy from one place to another with no transfer of matter. In Activity 2 on page 8 we had to model sound waves using an instrument. In our class we used a flute as the example and when the person blew into it, sound waves were produced. As they blew and changed the volume and pitch the sound waves changed. A sound wave is created when something vibrates. When something vibrates, longitudinal waves are created which we can hear. A longitudinal wave is a wave that transfers energy through compressions and rarefactions in the material that the wave travels which are all parts of a sound wave. In Activity 2 it states in some parts of the wave, the air molecules

In this lab, we will be doing 3 major things: 1) Collecting and organizing data to obtain resonant points in a closed pipe, 2) measure the length of a closed-pipe resonator, and 3) analyze the data to determine the speed of sound.

The interesting question is how waves can become meaningful sounds. First off we must know that sound is a wave. It is impossible for sound to be a particle or atom because if it was a particle the two different sounds would eventually collide and if sound was an atom one sound would deflect another and neither one of these situations ever happens. A characteristic of sound is that different sounds pass through one another, for example, a sound and its echo. Therefore, it is safe to conclude that sound is a form of wave. Sound is molecules vibrating back and forth creating what we call a longitudinal wave. However, very few times do we consider sound as flow of power yet that is exactly what it is. It is a power that flows through the air steadily. The speed at which it travels depends on the temperature and the

The sound waves are produced by a random oscillating crystal, and are inaudible to humans. A instrument called a

Insulate - to cover, line, or separate with a material that prevents or reduces the passage, transfer, or leakage of heat, electricity, or sound (Insulate ,2015, pg.1). In this experiment insulation is the main topic. Insulation is used in many things: a house, a refrigerator, walls, clothing, and types of drinking cups. Installation can be made of materials like styrofoam, plastic, and fiberglass. These can be used to keep things hot or cold. Insulation is most commonly for heat and maintaining heat energy. This experiment tests the insulation of several cups and how they keep liquids hot. Each cup used in the experiment has some insulation. The cups have different amounts of insulation. Each of these cups are generally used as insulators for many liquids.

The purpose of this experiment is to measure the speed of sound in air and to determine the effects of frequency on the speed of sound.

The design of our project was based upon the instruments seen in the Dr. Seuss novels. The instrument is multi-colored and similar to the color scheme found on the cover of the book, Oh, the Places You’ll Go. The shape and unique structure are also attributed to many distinctive instruments found in Dr. Seuss stories. We decided to have two mouthpieces available, so two people can play the instrument at the same time and the overall structure characterizes the disproportionate instruments seen in the books. Going with the theme, the sound created is also very interesting. When assembling the instrument, we had stuck wax paper between the parts of the pipe, creating a kazoo-like sound. We had chosen to use PVC-pipes in order to lock in the sound, leaving no air to escape, and funnels in order to amplify the sound being given off. Before our final design, there had happened to be another idea we were going for. The design had included a chamber that would contain soft air gun pellets or bb gun pellets that were capped off by 3D printed discs, covering each end of the side chambers. These discs would have holes that would allow air to enter the chamber, move the pellets around and create a rattle sound

These sounds are heard on a daily basis are being bent and altered in order for us to properly hear them. Engineers have used trigonometry in many rooms, that are created for the production of music, to help the sounds that are transferred to bounce off the walls. This motion helps the sounds to balance which makes it easier

Sound waves are nothing more than an energy transfer through a medium be it through a liquid, solid, or a gas. Sound pressure or intensity is measured on logarithmic scale in decibels dB which increases on an order of magnitude. For instance a quiet conversation would be around 30 dB and whereas the human pain threshold would be just over 100 dB. While the pitch or frequency of the sound is measured in hertz or Hz, the higher the hertz the higher the pitch of the sound and vice versa (Hildebrand, 2004).

Sound is usually something that people usually take as something simple. However, sound can be a very complicated topic. Sound is a wave of vibration (called a longitudinal wave) caused by a release of energy.

The snail like shape of the cochlear effectively boosts the strength of the vibrations caused by sound, especially for low pitches. When sound waves hit the ear drum, tiny bones in the ear transmit the vibrations to the fluid of the cochlea, where they travel along a tube that winds into a spiral. The tube’s properties gradually change along its length, so the waves grow and then die away, much as an ocean wave travelling towards the shore gets taller and narrower before breaking at the beach.

It is within this framework that I consider important to study the way in which sound is

What is a sound wave? A sound wave is produced by a mechanical vibration, such as a tuning fork. The vibrating object causes the surrounding medium, such as air, to vibrate as well.The wave travels through the medium to a detector, like your ear, and it is heard.As with any type of wave, a sound wave is also described by it's wavelength, amplitude, period, and frequency.

The ears are one of the most complex and interesting systems thats human body has and the sounds we hear are actually in many different parts deflected, absorbed, and also filtered by our different body parts. It's then collected by our pinnae (the external part of or ears), whose dimensions further affect the sound on its way into ear. There, vibrations are translated into signals, which are interpreted by your brain. In the 1930s, two scientists at Bell Labs, Harvey Fletcher and Wilden A. Munson researched this process and what they discovered has changed and affected how we as humans understand the hearing process.

From the time I was in the 5th grade I have played the flute in the band. The flute is an instrument that relies entirely on air to create sound. Pitch on the flute is varied through many factors such as breath support and air speed. The air creates vibrations that travel through the instrument creating different notes. As a little girl I remember my dad setting out my mom’s crystal wine glasses and showing me how to create music with them. It fascinated me how such a simple household object could create such beautiful tones just like I could with my flute. Therefore, when I was presented with the internal assessment for my IB physics class,
