  • Oedipus, The Movie

    627 Words  | 2 Pages

    Oedipus, The Movie After reading the play Oedipus the King, I had various expectations related to how the movie should be performed. The stage presentation of the story fulfilled some of my expectations but failed to satisfy others. Most importantly, the performance was an accurate rendering of the play. The characters in the movie were developed effectively and were portrayed precisely as I had perceived them. I thought that the movie lacked qualities including stage design, clothing, and

    are trains, planes, and automobiles. Industrial and construction noise can also contribute to external noise. In order to better define the noise present in a classroom, we must look at the classroom acoustics when the classroom is unoccupied and compare that to when the classroom is occupied. Acoustic standards recommended that maximum background noise levels for classrooms smaller than 10,000 ft3 do not exceed 35 dBA. Reverberation time (RT) should not exceed 0.6 seconds (ANSI SOURCE). Sadly, many

    creating simple complex musical pieces while gaining dexterity and technique. They can learn musical processes with keyboards and have fun at the same time. Electronic instruments can also be used in performance to enhance traditional and electronical-acoustics ensembles. A musical performance consists of a series of sounds played in time with appropriate tempo and dynamic changes. MIDI data, however, consists of a stream of information of note events generated by the electronic controller device. This

  • Speech Sound Disorders

    802 Words  | 2 Pages

    Speech sound disorders (SSD) are the most common communication disorder in the pediatric population, impacting approximately 10 to 15 percent of children between 4 and 5 years old (Gierut, 1998 & McLeod & Harrison, 2009). SSDs result in speech intelligibility, occurring from difficulties in motor production of speech, phonological awareness of vowels and consonants, syllable discrimination, and the ability to understand rhythm, stress, and intonation of words (Bowen, 2015). Children diagnosed with

    hypoechoic image from scanning some masses and fatty plaque. Since you can have something with low echogenicity you can also have an image with high echogenicity which we refer to as hyperechoic. This means that along with having a significantly different acoustic impedance there is also less attenuation due to absorption but more attenuation due to reflection. Being hyperechoic you will have higher reflected signals which can make something (like fibrous plaque) appear to be brighter than the surrounding

  • Ultrasound History

    880 Words  | 2 Pages

    Ultrasound is one of the most vital inventions in women health care. The advancement of wave technology throughout history formed the basis for the ultrasound. Ultrasound history is embedded in innovations on wave technology (Woo, 2015). Earlier designs of ultrasonic devices were not in the field of medicine until in the 1950s (Woo, 2015). Even then, the devices were employed for therapy before they were improved and used for diagnosis. Ultrasonic are waves that have a high frequency that cannot

  • Two Important Sounds In Our Life

    Sarvar Aliyev First Draft How it sounds to be 18. Presumably, everyone knows that seeing and hearing are the two main senses of people and the fundamentals of our life. These two sentiments are the essences for all human efforts. Although, both of these two higher senses might seem evenly significant, it is not always figured out that hearing has the more substantial effect in identifying the character of our lives. A dog barks, a sheep bleats

  • Analysis of electromechanical coupling coefficient of surface acoustic wave resonator

    695 Words  | 2 Pages

    A surface acoustic wave (SAW) resonators are widely used for frequency selection in mobile and wireless transmission systems [1]. SAW devices consist of piezoelectric substrate, interdigital transducers (IDT) and reflectors deposited on top of the substrate [2]. When voltage is applied at the electrodes, it generates electric fields, which produces piezoelectric strains propagating in both directions as shown in Fig. 1(b). Thus, surface acoustic waves are generated through inverse piezoelectric effect

  • Globe Theater

    1093 Words  | 3 Pages

    Because there was no lighting, all performances at the Globe were conducted, weather permitting, during the day (probably most often in the mid-afternoon span between 2 P.M. and 5 P.M.). Because most of the Globe and all of its stage was open air, acoustics were poor and the actors were compelled by circumstances to shout their lines, stress their enunciation, and engage in exaggerated theatrical gestures. What would seem most striking to a modern (Broadway) theatergoer about the productions staged

  • Speech Perception

    2007 Words  | 5 Pages

    listening. Mankind is constantly being bombarded by acoustical energy. The challenge to humanity is to translate this energy into meaningful data. Speech perception is not dependent on the extraction of simple invariant acoustic patterns in the speech waveform. The sound's acoustic pattern is complex and greatly varies. It is dependent upon the preceding and following sounds (Moore, 1997). According to Fant (1973), speech perception is a process consisting of both successive and concurrent identification

  • Leonhard Euler

    (1765). Like his teacher Johann Bernoulli, he elaborated continuum mechanics, but he also set forth the kinetic theory of gases with the molecular model. With Alexis Clairaut he studied lunar theory. He also did fundamental research on elasticity, acoustics, the wave theory of light, and the hydromechanics of ships. Euler was born in Basel, Switzerland. His father, a pastor, wanted his son to follow in his footsteps and sent him to the University of Basel to prepare for the ministry, but geometry soon

    peace in the world. The subjects of their songs were real people in a real world. They wrote and sang about survival. Their lyrics were simple and sometimes traditional melodies formed the basis of their songs. Their musical equipment was mostly acoustic and they performed to large audiences throughout the world. They released many albums. A favourite peace march song around 1963 was 'That Bomb has Got to Go'. In this song Seeger and MacColl describe the feelings and relate the events surrounding

  • ATRAC: Adaptive Transform Acoustic Coding for MiniDisc

    1980 Words  | 4 Pages

    ATRAC: Adaptive Transform Acoustic Coding for MiniDisc Abstract -------- ATRAC is an audio coding system based on psychoacoustic principles. The input signal is divided into three subbands which are then transformed into the frequency domain using a variable block length. Transform coefficients are grouped into nonuniform bands to reflect the human auditory system, and then quantized on the basis of dynamic sensitivity and masking characteristics. ATRAC compresses compact disc audio

    Sound a Sign of Life Five year old John nervously roams around the crowded store scanning for his mom. He shouts for her but gets no response. After 15 seconds he hears that familiar voice that he has heard all throughout his life, and gets the sense of hope and relief. The story Auscultation by Steven Church connects scenes of trapped miners communicating with rescuers by sound. As well as scenes of stethoscopes functioning on humans listening for the sound of life. Sound is a form of communication

    hear, we can better accommodate them in our day to day interactions. There are many approaches to the explanation of the elderly's difficulty with rapid speech. Researchers point to a decline in processing speed, a decline in processing brief acoustic cues (Gordon-Salant & Fitzgibbons, 2001), an age-related decline of temporal processing in general (Gordon-Salant & Fitzgibbons, 1999; Vaughan & Letowski, 1997), the fact that both visual and auditory perception change with age (Helfer, 1998), an

  • Flute Acoustics

    553 Words  | 2 Pages

    A flute blows a rapid jet of air across the embouchure hole. The pressure inside the players mouth is above atmospheric (usually 1kpa: just enough to support a 10cm height difference in a water manometer). (http://newt.phys.unsw.edu.au/music/) The work done to accelerate the air in this jet is the source of power input to instrument. Sound requires an oscillating motion or air flow. In the flute, the air jet, and the resonance in the air in instrument produces an oscillating component of the
