Explain What Frequency And Pitch Mean When Referringing To Sound
345 Words2 Pages
All sounds are created by vibration. The vibrations create a sound wave in the air by pushing air particles together and spreading them apart many times.
1) Explain what frequency and pitch mean when referring to sound
Frequency=The rate per second of a vibration constituting a wave, either in a material (sound waves), or in an electromagnetic field (radio waves and light) pitch= the quality of a sound governed by the rate of vibrations producing it, the degree of highness or lowness of a tone. -google definition
2) Why does sound travel through different materials at different speed?
Sound waves must travel through things such as solids, gasses and liquids. Sound waves move throughout all the mediums by vibrating. The molecules

The three most important properties of a wave are the wavelength, the amplitude, and the frequency. The wavelength is the distance from one point on a wave to the next identical point on the next wave. The amplitude is the distance from a waves rest position to either the crest or trough of the wave. The frequency is a rate which represents the amount of times a wave repeats

Lead them to point out that sound is made when there is a vibration. 3 Explain that the frequency of a sound is a measure of the number of vibrations or waves per second. 4 Explain that a sound with a high frequency will make a high-pitched sound, and one with a low frequency will make a low-pitched sound. 5 Explain that pitch is a measure of how

Throughout Canada, increasing use is being made of award winning Echo Sound Barriers to counteract noise pollution. As companies become aware of the advantages of the range of noise reduction solutions available from the Echo Barrier company, the impact of noise on the environment in Canada is reducing. This can only be an advantage to the health and welfare of the nation. Unacceptable levels of sound can come from many sources. Construction and building work, demolition sites, generators, airports and railways and even children playing in the garden can make life unbearable for those who live or work in close proximity.

Muslim neighbors have been so badly treated and had to leave their homes. Summarizing Bringa reasons as to why the violence has erupted in the local Bosnian community of Visnjica, is the extraordinary power or fear and uncertainty that the conflict imposed upon the community from the outside brought to the village. Another important reason is reinforcing cleavages in this case along ethnic lines all the homes destroyed in Visnjica were Muslim and as indicated by the movie all the Croats homes were left intact. Underlining similarities that characterize Chuck Sudetic book and Tone Bringa documentary film we can say that both of them emphasize more on the bottom up approach versus the top down, while providing their reasons why violence

Within the Deaf Culture movement, there is ongoing controversy on whether or not a child should have their “deafness” surgically removed. Cochlear implant surgery is an ever progressing technological advancement, and while many parents of Deaf children oppose this surgery, there is talk of sueing those parents who deny cochlear implants for children that are appropriate candidates for the surgery. Throughout Adam B. Zimmerman’s “Do You Hear the People Sing? Balancing Parental Authority and a Child’s Right to Thrive: The Cochlear Implant Debate,” this issue of legally overriding parental authority is examined with the use of scholarly language and credibility as a writer for the “Journal of Health & Biomedical Sciences”, as well as various forms

Different sounds are produced by different material, each creating a unique set of sounds. Percussion instruments include the drums, cymbals, triangles, chimes, timpani, bells, and xylophone. String The sound of string instruments comes from then strings vibrating the air around it. The strings may be plucked, bowed, or struck making them vibrate. There a many different types of string instruments such as the violin, cello, harp, and dulcimer.

Harmonics Harmonics create thin, pale and ghostly pitches played in the high register of the cello. By dividing the string with a finger, the cellist can shorten and double the intensity of the vibrating string. This creates pitches that are proportional to the strings

In Edison’s invention, the sound waves were recorded and engraved onto rotating discs and while the surface of the phonograph also rotated, a small device called a stylus mapped the channel, causing it to vibrate and copy the sound. The sound was then played through a horn (a vibrating body), which amplified the sound so that it was audible. The evolutions of musical instruments dates back to over 40,000 years ago and have continuously been developed in order to produce new and innovative sounds that have never been heard before and by the end of the 19th century, these innovations saw the first use of electronic devices to create sound and

This essay will discuss about hearing and visual impairments, which are two of the most prevalent sensory impairments. In order for the assignment to be meaningful, there will be an introduction for each disability and addressing of the challenges facing by the individuals with the respective disability as well as the strategies and teaching tips to overcome the challenges. Introduction of Visual Impairment Visual impairment can be defined as the limitation of one or more visual system’s functions. The most common visual impairments affect the visual acuity, visual fields and colour. Visual impairment can be represented by low vision and blindness.

Sound is measured in Hertz (Hz) and as humans, we can hear from 20Hz – 20,000Hz(20kHz) and as our ears are picking it up, it’s moving at a speed of 1130 ft/s. Sound requires a medium to travel and the medium is the air pressure. What this means is that when the atmospheric air pressure is higher than normal that means sound has been created and the molecules begin to travel through the air pressure, this process is called “compression” and once they travel back its known as

It is useful for distant warnings and communication. This is the detection of vibrations. It is a mechanical wave that travels through different mediums such as air or water but also through solids like in different metals. Sound wave travel through those mediums and they are created by vibration of object, which causes the air to vibrate as well. The vibrating air reaches the ear where the eardrums can start to vibrate and therefore the brain can interpret it as a sound.

The mechanical vibrations transmitted through a medium; solid, liquid or a gas generates a sound wave. The sound is an energy, which deflects the particles of a medium in the same direction, and itself travel as a longitudinal waveform with areas of compression and rarefactions. The image generated by ultrasound is essentially based on similar principle by means of a machine, which includes an ultrasound transducer and a screen. The transducer contains a piezoelectric crystal made up of lead zirconite, which generates an ultrasound beam on applying an electrical current to the transducer. These signals travel through a medium in the body and after striking with various tissues, return back to the transducer.

The Development of Absolute Pitch I. Michael Jackson, Celine Dion, and Stevie Wonder are all brilliant musicians that each holds an amazing ability. This allows them to instantly identify a note like a C or E-flat. What these musicians have is an ability called absolute pitch. Absolute pitch is also known as perfect pitch is the ability to recognize a note without external reference. You could also associate the tone with the position of it on a musical scale.

The purpose of this lab was to observe the phenomenon of resonance in an open ended cylindrical tube and use resonance to determine the velocity of sound in air at regular temperatures. A hypothesis for this lab was that if the frequency of the tuning fork increased, then the length of the tube to achieve resonance will increase because of the high amplitude of the vibration. The resonance of the open-closed tube was found through these steps. First, the tube was filled with water with an inner tube inside the outer tube. The water temperature was measured.
