What Is Equilibrium?

These parts make up the sound waves and they travel through a medium which is the material that a wave energy travels through. On page 10 in Activity 2 we had to fill out the table on how to make a louder sound and we learned that to have a louder sound the compressions have to be larger and to increase the frequency the compressions also had to be larger. When we did the activity with the slinkies this was the case because when we had more compressions the sound was louder and the frequency increased. In Activity 1 on page 4 we learned that sound intensity is how much sound energy passes through a certain area in a certain amount of time as it spreads out from the source. Decibels are a unit of measure that indicates the relative intensity of a sound. In Activity 1 on page 5 when we were looking at the table it showed us that as the sound intensity increases the decibel increases because the decibel measured how intense the sound was. According to the chart on page 4 the decibels at a quiet library is 40 dB and the relative intensity is 1000, however if the noise source is some explosions then the decibels is 160 and the relative intensity is

Form and fiberglass were porous materials which allowed them to more greatly affect the propagation of sound and absorb more of the sound waves. As the frequency increased, so did the sound absorption of all materials since higher frequencies were supposedly easier to control. Bibliography 1. Berg, Richard E. "Sound." Encyclopedia Britannica Online.

I also think about how humans and animals hear different frequencies. Someone my age in there 20 's would be able to hear the door bell ring, while someone in there 70 's may not hear it. This measures how over time our frequencies can. A dog on the other hand can hear very high-pitched

In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.

The noise may influence communication as if it is noisy then, you may not be able to hear what the other person is saying, and then misinterpret what they are saying. Where as if it is quiet then you would be able to clearly understand what they are saying to you. So if a person has difficulty hearing then you would need to make sure that it is quiet so that they can hear what is being said. This would affect communication because if it is too loud then people will start to misunderstand what is being said or may not be able to understand what is being said all

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

In addition to the practical work of recreating a soundtrack of a Wallace & Gromit clip, a learning report on the subject had to be submitted. The soundtrack needed to be created by using a type of sound design known as Foley. Other than that, dialogue, wild track and music had to be added as well. Afterwards, these sounds would be synced to the video track and adjusted accordingly. “Sounds are vibrations traveling through the air as sound waves” Apple Inc. (2010). “Big sound waves have what's called a high amplitude or intensity and we hear them as louder sounds” Woodford (2009). If we add more gain to the sounds of lower intensity we risk adding noise to them and ruining the recording, this is known as signal to noise ration.

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.

Every sound in the world has a frequency and with a frequency comes a wavelength. For notes to sound plesing to the ears, the wavelengths of the notes must share a common intercept point. This syncing of notes is called consonance. When the wavelengths of te notes dont

A drawback of infrasonic correspondence is the generally abnormal state of foundation clamor in this low recurrence range caused by wind and human produced commotion. Machines, for example, automobiles, planes, and generators are progressively infringing on elephant correspondence channels as the human populace keeps on developing and as sightseers negligently attack the elephants' space with commotion

Musicians know that all vibrating objects make sounds. Frequency measure how many times a string vibrates up and down. If a musician changed the length of the string, it also changed the frequency. High frequency will always equal a high pitch. When an octave is increased the frequency will double. Pythagoras discovered different sounds could be made with different weight and vibrations. Due this discovery, they also realized pitch could be controlled by the length of the string.

Have you ever wondered why glass bottles made a sound, kind of like a music note? Well, this paper will explain how this works. The paper will be talking about sound, sound waves, standing waves, musical note names and frequencies, resonance, and closed-end air columns. Closed-end air columns will be a main focus in the paper, studying the physics behind it. Glass bottles are an example of a closed-end air column. Therefore, the more water inside the bottle, the lower the note, and less water would be a higher note.

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

B. Most professional high frequency machines produce a frequency of 100,000-300,000 Hertz (cycles per second).

The red bar on the left acts as the driving piston. If it moves in a sinusoidal manner from left to right, then the wave that is produced will be a sinusoidal wave. Since the wave is sinusoidal, the wavelength, amplitude and frequency are constant. This is seen in nature as a tuning fork, which produces a periodic sound wave. In a one dimensional tube as shown above, each particle undergoes simple harmonic motion. The volume that is contained in one wavelength also undergoes this same motion. We can represent the displacement of this volume as:
