What is Sound?

The Production of Sound:
Sound is the vibration of waves moving through air or water caused by a vibrating source which produces rhythmic vibrations in pressure. The air or water molecules collide and transmit the pressure away from the sound source; this is the process which causes sound. Sound can be measured by using several different equations, these include:

The Equation to calculate the frequency of a wave length
V=fγ
Velocity = Frequency x Wave Length

This equation is used to calculate the frequency of wave lengths. It states the relationship between the Velocity of a wave and its Frequency and Wave Length.

The equation to calculate the intensity of a sound
S= γ/T
Speed= (Wave Length)/Time
This equation is used to calculate how fast sound is traveling. It states the relationship between the Speed of a wave and its Wavelength and the Time that the sound lasts for.
Noise and Music
Music and Noise are not the same thing, this is as music’s waves are repetitive as seen in figure 2 and is pleasing to hear while noise has random wave f...

    If you put your finger gently on a loudspeaker you will feel it vibrate - if it is playing a low note loudly you can see it moving. When it moves forwards, it compresses the air next to it, which raises its pressure. Some of this air flows outwards, compressing the next layer of air. The disturbance in the air spreads out as a travelling sound wave. Ultimately this sound wave causes a very tiny vibration in your eardrum - but that's another story.

  • The Physiological and Psychological Effects of Music

    838 Words  | 2 Pages

    Whether you’re a devoted music enthusiast or you just listen to the radio to pass time, we all listen to music. However, when listening to music, nobody stops to think about what they are doing. Nobody stops to contemplate how the music they are listening to affects them psychologically. We just listen to the music and enjoy ourselves. In fact however, a great deal of research has been done to determine the psychophysiological effects of music. Many studies have been conducted to determine whether music can help people who suffer from psychological and medical disorders, Scholars continually debate whether music can influence behavior, and researchers are attempting to understand what is happening in our brain when we listen to music.

    The mechanical motions of the ossicles directly vibrate a small membrane that connects to the fluid filled inner ear. From this point, vibration of the connective membrane (oval window) transforms mechanical motion into a pressure wave in fluid. This pressure wave enters and hence passes vibrations into the fluid filled structure called the cochlea. The cochlea contains two membranes and between these two membranes, are specialized neurons or receptors called Hair cells. Once vibrations enter the cochlea, they cause the lower membrane (basilar membrane) to move in respect to the upper membrane (i.e. --the tectorial membrane in which the hair cells are embedded). This movement bends the hair cells to cause receptor potentials in these cells which in turn cause the release of transmitter onto the neurons of the auditory nerve. In this case, the hair cell receptors are very pressure sensitive. The greater the force of the vibrations on the membrane, the more the hair cells bend and hence the greater the receptor potential generated by these hair cells.

  • Noise Induced Hearing Loss Essay

    Noise is ubiquitous in our environment. (Pediatrics , 1997) It is undesirable sound, unwanted sound. Sound is what we hear. It is vibration in a medium, usually air. Sound has intensity, frequency and duration. The ability to hear sounds at certain frequencies is more readily lost in response to noise. (Pediatrics , 1997). The further you are from sound the less effect you hear it but the more closer you are to sound the louder it is.

  • The Physics of Ultrasound

    Ultrasound is sound waves that have a frequency above human audible. (Ultrasound Physics and Instrument 111). With a shorter wavelength than audible sound, these waves can be directed into a narrow beam that is used in imaging soft tissues. As with audible sound waves, ultrasound waves must have a medium in which to travel and are subject to interference. In addition, much like light rays, they can be reflected, refracted, and focused.

    Sound waves take the form of compressional waves and are caused by vibrations. Sound waves are distinguished by their speed, pitch, loudness and quality (timbre) (Lapp, 2003). There are a few parts of sound waves that we should be familiar with to better be able to understand the physics of music. The crest is the highest point of a wave, while the trough is the lowest. The wavelength of a wave is the distance between two adjacent parts of a wave, like from crest to crest, or from trough to trough....

    Sound is essentially a wave produced by a vibrating source. This compression and rarefaction of matter will transfer to the surrounding particles, for instance air molecules. Rhythmic variations in air pressure are therefore created which are detected by the ear and perceived as sound. The frequency of a sound wave is the number of these oscillations that passes through a given point each second. It is the compression of the medium particles that actually constitute a sound wave, and which classifies it as longitudinal. As opposed to transverse waves (eg. light waves), in which case the particles move perpendicular to the direction of the wave movement, the medium particles are moving in the same or opposite direction as the wave (Russell, D. A., 1998).

  • Sound and Image in Motion Pictures

    2314 Words  | 5 Pages

    Motion pictures and television are audio-visual mediums and so of course engage both our visual and aural senses. The meaning and emotion of a piece is commonly thought to come from the image and that the sound at best just duplicates the meanings from the image. For example Aaron Copland has said that a composer can do no more than" make potent through music the film's dramatic and emotional value."

    We have different emotions that we have experience daily. Some people used to listen to music in order to contract emotions. The precise structure through which music evokes emotions is a rich field of research, with a great amount of not explained questions. Why does music talk to our emotional brain? Why do we perceive emotional information in musical features? Why do we feel the urge to move when hearing music? Through increasing scientific understanding of the universal as well as the individual principles behind music-evoked emotions, we will be able to better understand the effects that music-listening can have and make better use of them in an informed
