Sound Waves

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

Density is the amount of matter per unit of measurement (Merriam-Webster. Merriam-Webster, n.d. Web. 26 Aug. 2016.). If water has a density of 1.0 g/mL and you place a substance with a density of 1.8 g/mL the substance will sink because it is denser than water. Density is often measured in g/cm^3 or g/mL because the formula for density is D=m/v.

These averages we determined from the trials can be compared to the accepted speed of sound (344.2 m/s in this specific temperature), and we determine the relative error percentages:

In longitudinal waves the object doesn’t exactly follow the waves fully instead the object moves in a back and forth motion while the waves continues to move forward through the object. While in transverse waves the object doesn’t follow the waves as well and just moves up and down in the same position.

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.

Over the past weeks I have been adding sounds to a moving image clip. Research of the science behind sound and of professional sound recordist would be key, anything from microphone techniques to personal safety would need to be taken into account on the recording side, whereas an understanding of the software and tools within it would be needed for the sequencing.

As the distance to an object is determined by measuring the time of flight and not by the intensity of the sound, ultrasonic sensors are excellent at suppressing background interference. Virtually all materials which reflect sound can be detected, regardless of their color. Even transparent materials or thin foils represent no problem for an ultrasonic

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).

As the project develops I will explore more tribal water rituals as these rituals can be based around water and the spiritual power of water and sound (music), such as the tribal woman of Vanuatu. As I am personally not of these tribal decent, I will use what research I can on these performance ritual, to generate sound using modern methods, such as an electric guitar, effects pedals, computer based music modification and Video. I will explore the similarities and achieve a representation of water flow in the form of sound, music and video.

Detects different physical characteristics of pressure waves: • Pitch: perception of the frequency of sound waves (umber of wavelengths that pass a fixed point in a unit of time) • Loudness: the perception of the intensity of sound (the pressure exerted by sound

According to Gill (2012,p. 11) the equation for Acoustic impedance is Z=ρc, where (Z=Acoustic impedance, ρ =density of medium and c =velocity of beam). From this equation is understood that acoustic

Sound is a wave, and a wave can be remembered as a medium, carrying energy from one point to another. The sound wave has a resemblance of a slinky in its nature, for many reasons. The disturbance goes from one place to another, carried by the medium. Typically, the medium will carry energy through the air, although it could be any substance like water and steel. There is an original source of the wave; anything from someone’s vibrating vocal chords, or a tuning fork. Then, the sound is transported through the medium through particle-to-particle interaction. If the sound wave is moving through the

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

This can be represented as : v2 = (elastic property / inertial property). Where the elastic property is usually the bulk modulus or Young's modulus of the medium, and the inertial property is the density of the medium.
