Harvey Munson Research Paper

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

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

The physiology of hearing starts with a vibration that occurs in the air which sends an acoustic signal to the ear drum. The signal is transduced into a mechanical signal that transmits through the inner ear and the cochlear nerve. Finally, the signal is

The authoritative amplifier section has 7 separate output stages with equal circuit topology, with every channel rated at 125W, to easily drive modern loudspeakers.

Hi Amy. I have just wanted to expand on your post. In the beginning of chapter 10, Sacks explores medical history. He argues that the course taken by sound vibrations, from their entry into the external ear canals, through the eardrums on either side to the small bones, the ossicles, of the center ear, to the snail-molded cochlea, was initially worked out in the seventeenth century. It was believed then that sounds were transmitted by the ear, becoming enhanced in the cochlea "as in a musical instrument." After a century, it was found that the tapered shape of the cochlear spiral was differentially tuned to the scope of discernable frequencies, responsive to low sounds at its wide base, high sounds at its narrow apex. At last, by 1700, it was

a much deeper sound and have a much lower frequency than what you are used to hearing. When

What should we know about hearing loss? The main causes for hearing loss is head trauma and exposure to loud sound. The only way we can take care of ourselves is by knowing how to.To prevent hearing loss we can turn down the volume, use earplugs or remove ourselves from situations where noise is excessive. More Importantly, Digan states,”The major source of dangerous noise is a personal media player combined with a pair of earbuds”, ( Pg.11). For example, Digan writes,”Sound is measured in

In the model of Jeffress, this is detected by the input from one ear being compared with multiple time-shifted versions of the input from the other ear. The time shift that produces the maximum degree of similarity indicates the direction of the sound source in the horizontal plane. In the formulation of Jeffress, the time shifts are produced by axons of different lengths. The output neurons detect coincidence in the time-shifted inputs from the two

The length of five spaces in a scale is known as a perfect fifth (Shah 42). C major and A minor start at the head of the circle (Shah 42). At the head of the circle going clockwise, notes rise at a rate of fifths and do not stop until a limit of seven sharps is made (Shah 42). Going counter-clockwise, the notes go down at a rate for fourths until a limit of seven flats is met (Shah 42). When the very end of the circle is reached, six flats and sharps will have overrun each other (Shah 42). Also on the circle, one will begin at a certain pitch, skip twelve tones, and make it back to the pitch they started with (Shah 43). Pitch is in relation to the wave’s frequency (Petersen 1). The pressure vibrates rapidly wit high notes because of their high frequency (Petersen 1). Volume and pitch are the two attributes that make up sound (Petersen 1). Noise level and volume are in relation to the pressure’s amplitude (Petersen 2). The force per unit area, Pascals, is usually used to calculate pressure (Petersen 3). Frequency is equal to string length (Petersen 3). The rate of a frequency of noise of at least two tones is known as musical interval (Shah 20). A geometric sequence is fashioned from the frequencies of an octave (Petersen 4). An exponential function would be seen if such a sequence was graphed (Petersen 4). An

Years ago on the elementary playground, I grabbed the cold steel bars on the monkey bar set as I swung myself from bar to bar. As the sun beats down on the entire yard, a fellow peer approached me and asked the same question that I have heard hundreds of times before, ''What are those things in your ear?'' I rolled my eyes in response. Even though I was sick of this question, I answered it anyway. I lectured about how I had hearing loss, and the things in my ears were hearing aids designed to help me hear better.

The fifth flash video shows a cross section of the basilar membrane that moves as the fluid within the cochlea is displaced. The sixth and last flash video models the conversion of the hydraulic energy into electrical energy as the hair cells are displaced, transferring the electrical energy from the hair cells into the auditory nerve that consequently passes the information to the auditory cortex in the brain for

The author argued that dynamic range has not decreased from this process. He says that there was just heavier limiting which decreases the overall sound which makes everything sound quieter. Some record producers might agree that everything as whole might have gotten quieter from increasing use of limiters which “limit” the sound of the overall song. Many audio engineers have disagreed with him and say that it pretty much does the same thing as compressing the whole song. They have argued if the loud parts get quieter and the quiet parts stay the same that the range between them is closer, which results in less dynamic range. The author seems to be a little biased in the way he doesn’t state that without explicitly the processes being identical they effectively do the same thing with the range of

Applying Sonnox Inflator to improve character and overall volume of the mix as well as use Brainworx Hybrid v2 to mono frequencies below 150Hz and to add a little width to the stereo field.

Compression is the process often used to make music appear to be louder without increasing its peak amplitude. By compressing the loudest signals, it becomes possible to increase the overall volume of a signal without exceeding the limits of a reproduction device or medium. This process has created what many call the loudness wars.

In addition, it is also paramount for the audio quality to be consistently audible for all members of the audience. This will be achieved by utilising a system design configuration that focus’ on clarity and direction whilst also rendering itself sympathetic to the sensitive ears of the general public not attending the event.
