ULTRASOUND PHYSICS Name Institution a) Calculate the Acoustic impedance of subcutaneous tissue, muscle and bone. Assume subcutaneous tissue has a density of 1060kg/m3 (Hedrick 2003), muscle has a density of 1104kg/m3 (Madjor 2008) and bone has a density of 5065kg/m3 (Hedrick 2003). Give your answer in Mrayls. Please use speed of sound as 1540m/s for tissue, muscle and bone In ultrasound, Acoustic impedance (Z) is the quantity of measurement of resistance to sound when passing through a medium

The major acoustical issues in public buildings are concerned with the exclusion of outdoor noise and the separation of noise generated within the buildings. This chapter will consider specific types of public buildings in which acoustic designs are a matter of importance, such as schools, offices, libraries, recreational buildings, hospitals and government buildings. To obtain a space free from the annoyance of noise and excessive reverberation, a few step one could take would be as follows: planning

absorption panels. This should be implemented by the architect during design (Passero & Zannin 2012). A retro fit of sound absorption panels is possible, however inconvenient. Varjo et al. (2015) carried out extensive acoustic testing in a controlled open-plan office environment. Use of acoustic absorption panels and audio masking techniques demonstrated a reduction in irrelevant noise by up to 36dBA at the 2K position on the frequency spectrum – which is the range of human speech. Focusing on intensive

Abstract Stethoscopes have been around for nearly more than 200 years. From the early modern stethoscopes made of brass and wood, to common acoustic stethoscopes doctors use these days. Now, digital/electronic stethoscopes have been invented in which they are advanced and has more uses than acoustic stethoscopes. However they are much more costly than other stethoscopes and also tend to be at a heavier weight. These digital stethoscopes provide detailed information and have many functions to for

Tatiana Lyons SLHS3305W Assignment Three 12/1/16 Research Article Critique Lee, Potamianos, and Narayanan studied acoustics of children’s speech: developmental changes of temporal and spectral parameters in 1998. The researchers conducted the study to explore the relationships between different aspects of speech (formant frequencies, fundamental frequency, and segmentation patterns) and age and gender. Better understanding of these relationships would provide information that could be used to improve

Introduction The research is specifically carried out on Particle Sorting using the interplay between the Travelling Surface Acoustic Wave and the Stationary Surface Acoustic Wave. Sorting individual cells/particles of interest from a heterogeneous population has been of critical importance in biological studies and clinical applications, such as single cell sequencing, rare cell isolation, and drug screening. The introduction of “lab-on-a-chip” (i.e., small-sized analytical devices) has spurred

Sound of Waves Test Answer each of the following questions thoroughly. I will be grading on thoughtfulness and how well you explain your answer. For the factual questions, you just need to get it correct. This first section does not need as much explanation, you may give a short response. Why was Shinji’s mother angry when she first received Hiroshi’s post card? She was angry because Hiroshi had sent her an expensive post card, and she said "kids these days don't know the value of money

The first time I realized I had a speech impediment I was 5 years old. My cousins and I were sitting on the back porch of my grandmother’s house, on a hot summer afternoon in August. We were talking about how pretty the flowers looked in my grandmother’s backyard, when I said, “I just love lellow flowers.” As soon as that statement left my mouth, everyone laughed at me. I remember thinking, “Why are they all laughing at me?” They asked me to say it again, and I said “lellow.” Until they told me

When listening to music do you ever wonder how it was formed? We do not think about that. So how is music formed? Music is formed when a sound is produced when something vibrates. The vibrating body causes the medium around it to vibrate. With the vibrations moving in the air they are called traveling longitudinal waves. Longitudinal waves allow us to hear. By allowing us to hear, it allows high and low pressure to form called compression and rarefaction. What behaviors do air vibrations cause

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
