Acoustic emission

The McCormick Tribune Campus Center has two primary components, the one-story building that has multiple different activities for students and guests, and the long stainless steel tube that is placed directly above the roof of the building. The function of the steel tube is that it is designed to greatly muffle the noise and vibration generated by the passing commuter trains. According to IIT, the tube muffles the train noise noise from an average 120 dB to about 70-80 dB outside the building, about

Ultrasound technicians make more money than a Radiology Technician even though they are very similar in the job requirements. The median salary per hour is 28 dollars and 67 cents(“Diagnostic Medical Sonographer Salary” 1). Ultrasound detects a woman's ovulation and it can diagnose a pregnancy(Lewis 2). Sonography is harmless and it when you use a small probe and special ultrasound gel that is applied to the skin(Radiological Society of North America and American College Of Radiology 1). Common uses

A sound wave is a disturbance that repeats regularly in space and time and that transmits energy from one place to another with no transfer of matter. In Activity 2 on page 8 we had to model sound waves using an instrument. In our class we used a flute as the example and when the person blew into it, sound waves were produced. As they blew and changed the volume and pitch the sound waves changed. A sound wave is created when something vibrates. When something vibrates, longitudinal waves are created

ssues individuals can face in the oral production of sounds. For instance, some individuals have difficulty in producing speech sounds correctly as a result of: learning, physiological functions, or differences in anatomical structures. Such individuals with articulation and phonological disorders can range from minimal problems to more profound and severe ones. On one extreme, the problem could be minimal, such as interfering with the way one or two sounds (/s/ or /r/) are produced; on the other

For many decades now, sound advances in the ultrasound technology have become a successful innovation towards access to 3D images of a fetus as it continues developing in the womb. This innovation has helped pediatricians to gain clinical insights on the growing fetus and parental development of the mother. These images also serve the doctors with information that is used in determining the condition of the fetus all though its growth until it is ready to be born. However it some people think that

Part B Explain the difference between music and noise. Make specific reference to the musical scale. As the hearing is one of the most important ability a person can have it has a great deal of benefits. This allows an individual to hear sounds from a mechanical wave which is then transferred to stimulate the hearing organs inside the body. The mechanical wave is only able to transfer energy through a medium, the two types of waves that associate with the mechanical is both the longitudinal and the

As audio engineers it is our duty to bring the highest quality audio to all of our projects. These can range from studio recording, radio, TV, movies, games, forensic audio and what we will be going through in detail, live sound. Any form of live event, be it a rock band's concert, orchestral performance, stage play or even live sports events will need some form of sound reinforcement. Sound reinforcement consists of an arrangement of microphones, signal processing, mixing, amps and loud speakers

For the recording of “Our Greatest Fear” by Marianne Williamson I used the Zoom R8 recorder pared with the Wharfedale DM3, supercardiod dynamic mic. What I learned during this recording segment was that not all mics work best for certain applications. Because of this mic having a supercardiod pattern, meaning the polar patterns is narrow in the front, speaking closely to the mic was a must. The great thing was that most of the background noise was low for the most part. The recording was done in

The Physics of Diagnostic Ultrasound Introduction Diagnostic ultrasound is one of the most common forms of medical imaging in use today. When people think of ultrasound images or sonograms as they are also referred to, they may recall grainy black and white images that are similar to x-rays. However, with the exception of perhaps developing fetuses, most have very limited knowledge of what they are actually looking at, let alone how those images are created. Many people are aware that sound waves

Hyperfunctional Voice Disorders Hyperfunctional voice disorders are voice problems that happen when uncontrollable tightening (spasm) prevents the vocal cords from working properly. Vocal cords normally move back and forth to make sounds when air passes through the voice box (larynx). If you have a hyperfunctional voice disorder, the area of the brain that controls vocal cord movement does not send the right signals. This causes the vocal cords to spasm. Hyperfunctional voice disorders might also
