Physical science is the study of non-living matter which I will be talking about the physics of music, and how pitch and frequency play a role together in science. Physics is known to be the most fundamental science, based on the principle and concepts. It deals with matter, motion, force, and energy, (Shipman-Wilson Higgins, 2013). In this report I will be dealing with pitch, frequency sound and waves which are also dealing with physical science and how they our related.
Sound is (a) the physical transmission of a disorder (energy) in a standard and the physiological response generally to pressure waves in air. However, the sound spectrum has much lower frequencies and is much simpler, with only three frequency regions; the infrasonic region (f<20Hz), the audible region (20Hz20 KHz), (Shipman-Wilson-Higgins, 2013). Depending on the volume of sound can be determined as a low or high frequencies.
Sound is a type of longitudinal wave that originates as the vibration of a medium (such as a person’s vocal cords or a guitar string) and travels through gases, liquids, and elastic solids as variations of pressure and density. The loudness of a sound perceived by the ear depends on the amplitude of the sound wave and is measured in decibel, while its pitch depends on it frequency measured in hertz, (Shipman-Wilson-Higgins, 2013).
We hear sound because circulating conflicts cause the eardrum to vibrate, and feelings are transferred to the acoustic nerve through the fluid and bones of the ear. For example loudness is a relative term. One sound decreases source. As the sound is propagated outward, it is “spread” over a greater area. The minimum sound intensity that can be detected by the human ear...

...tify any musical notes by memory. There is a certain scale used to determined sound of perfect pitch. The music scale consists of tones and mostly scales and octaves repeating themselves.
For instance, C major is C D E F G A B [C] which our the scales to music, with the bracket indicating that the last note is an octave higher than the first C you started with. A single scale can be revealed at many different pitch levels. Which are the rules to music, from playing instruments to singing a song; this is the fundamental building blocks of sound in music.
Pitch can be interrupted differently due to who’s listening. Everyone will hear something but everyone will determine their on sound. This is really amazing to me. Being a musician, either singing or playing an instrument can help your ear hear the same thing but you will always have a different interruption.
This may happen unconsciously, as is usually the case with soft background noise such as the whoosh of air through heating ducts or the distant murmur of an electric clothes dryer. Sometimes hearing is done semi-consciously; for instance, the roar of a piece of construction equipment might momentarily draw one's attention. Conscious hearing, or listening, involves a nearly full degree of mental concentration. A familiar instance in which listening takes place would be a casual conversation with a friend or colleague. In such cases, the sound waves entering the ear are transferred to the brain, which then
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.
Most people are familiar with the word "music", however they barely consider the definition of it. After carefully think, everyone has their own opinions on this term and it is hard to have an uniform criterion of music sounds. According to the text book, Michael B. Bakan states five propositions to define the music. The first one is about the tone and the second one talks about the music is organized in some way. The next two are claims that music is human organized and a product of human intention and perception. The last proposition argues music cannot separate from Western culture. Among these propositions, I think the music is a product of human intention and perception is most interesting and worth to discuss. So I assert that the most
Sound is created by vibrations that travel in waves, with the longer, more spread out waves being lower pitched sound, and shorter, closer together waves being higher pitched sound. Sound waves travel through the air or water (or whatever is in their way) to reach your ear and vibrate your eardrum, which in turn lets you hear.Sound can not be heard in space because there is no air for it to travel on. Volume is measured in decibels, with a pin drop at about 15 decibels, a 12-gauge shotgun being at about 160 decibels, and a normal conversation at about 65 decibels.
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.
When studying Physics of Music, I was interested to research the topic of sound reflection in a theatre as I work at the Royal Manitoba Theatre Centre and wanted to research the acoustics in a theatre. In this paper, I will be using published articles to research the relationship of how people in the theatre receive sound and how the actors are able to portray sound in their space.
Materiality is a world usually describe something tactile, which is physically can be tough, visual image has the haptic visuality which proves that it visual image has its own kind of materiality. How can sound have its own materiality as well? “Sonic materiality” is term that represent how the materiality in the sound field.
Sound is actually a pressure wave; it is produced by a mechanical disturbance in the medium (in most cases- air) in which it is openly adjacent to. After the sound is first produced, it continues to disturb adjacent air particles and causes them to vibrate and hence the vibrations travel to the following adjacent air particles and so on like a chain reaction; however as the sound vibrations travel through the air particles, the vibrations and the loudness of the sound grows weaker and hence after a certain distance- the sound seizes to travel any further. Out of the three states of matter, sound is further travelled through gas/air as the particles are more spaced out so the vibrations are greater and freer to move around, hence the sound travels further and faster. Through liquid- sound vibrations are more delayed as the particles feel thicker to travel through and they are closer together hence the vibrations are not so great and the sound does not travel as far neither does it travel as fast. Solids are the hardest for sound to travel through as the disturbance of sound vibrations through the particles are more difficult to travel as the particles of the object/s are more slower/still so the sound is not able to vibrate/travel to its full potential- this is why sound does not travel to far through walls etc. Sound from solids is best exposed by two solids colliding together so that the particles get a stronger vibration and collide heavier with each other; then the stronger vibration travels further through the additional particles of the object and through other particles of matter. The sound waves are produced by the vibration of an object of which causes the air particles surrounding the object to vibrate- they...
A sound wave is a longitudinal, mechanical wave that transfers energy whilst compressing and refracting through a uniform medium. Therefore, as sound waves move through a uniform medium, the wave will experience a gradual reduction in it’s power. When sound waves pass through the medium it interacts with the molecules and the energy is transferred to the uniform medium, as heat is generated from the molecules vibrating back forth. The heat generated from the transfer of energy reduces the power of the wave. In particular, medium uniforms which are solid gradually remove the power, whereas dense mediums result in a rapid loss of energy (Henderson, 1996).
Some people may need assistance in being able to amplify those sound vibrations, which other people’s auditory system may process normally. People that have difficulty hearing may often be referred to a hearing aid device. The device amplifies the sound vibrations which are hear clearly by people without the device, but may not be heard by people who need the device. Hair cells within the ear are able to sense sound vibrations that are louder than usual, and transform them into electrical signals that are sent to the brain and processed as sound. The larger the damage to the hair cell’s in a person, the greater the hearing loss is. Depending on the magnitude of the hearing loss, will also determine the amount of amplification needed to allow for the hearing to reach a normal range. The downfall to this is that there are limitations as to how much you can amplify a sound through the hearing aid device. Also another factor is that if the inner ear is damaged to a certain point, then even with a hearing aid sound vibrations may not be able processed into electrical signals to be received by the auditory nerve
Sound is one constituent of music. Sound is made from repeating sound waves. The musical pitch of each note has a equivalent frequency which is measured physically in cycles per second which is known as hertz. There are various mathematical relationships between the notes played in music and their frequencies. Rhythm and music are just like numbers and mathematics. Rhythms measure time. Measure is the gap between two bar lines on the staff that represents the division of time by which air and movement of music are regulated. It is well known that when you play a few notes together or even repeat the same note on an instrument, you care creating something called a rhythm.
...s a set of rules which musicians must follow. Also just like any official language, music can be used to communicate emotions. In order for somebody to understand music they must have some sort of knowledge about rules in order to appreciate musical experiences. Every culture is different, every language is different and every music is different, but to fully appreciate the music; listeners must be musically literate. In our first week of class, “Khoomi” was our first musical example and all the students were confused about this type of music. But now with my little knowledge about music and how diverse it is, I learned to appreciate it more.
Hearing is known to be an automatic function of the body. According to the dictionary, hearing is, “the faculty or sense by which sound is perceived; the act of perceiving sound,” (“hearing…”). Hearing is a physical and involuntary act; therefore, unless one is born with a specific form of deafness, everyone has the natural ability to hear sounds. Sounds constantly surround us in our everyday environments, and because we are so accustomed to hearing certain sounds we sometimes don’t acknowledge them at all (or “listen” to them). The dictionary definition of listening is, “to give attention with the ear; attend closely for the purpose of hearing,” (“listening…”).
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).
There has to be definite sound frequency at which all matters vibrate as one. Some architectural spaces can cause a faintest sound to magnify and cause the whole space to vibrate, affecting all inside
