COMD 5070: Exam 1: Week 4 (Digital Systems) What is Digital Sound? MP3 vs. Tapes/Vinyl Music on mp3 players vs. tapes or vinyl records: "it's different", "it's clearer", "it's more convenient", "it's better" What is Digital Sound? Can your ears hear digits? It's not the sound itself that is digital – sound is still perceived as air vibrations, but the way the sound is stored is digital, stored in numeric form. However, the sound is played in analog form. ...

Sound - a form of mechanical energy produced by vibrating objects that is transmitted by pressure waves through a medium - needs a medium with particles to travel/propagate - cannot travel in a vacuum (medium with no particles) Mechanical Energy - has to be transmitted - propagated from one point to another - need a medium (can't propagate without a medium) Cycle - used to describe any changes in particle motion (particle displacement, density, or molecules, pressur...

What is an artifact? not true representation of our patients anatomy or a structure in the image that does not correlate directly with actual tissue Artifacts include missing reflectors structures not representative of tissue spatial misregistration of reflectors In other words artifacts include reflections that are not real, not seen on the image, incorrect size/shape, incorrect position and incorrect brightness Artifacts occur because an error occurs somewhere in t...

What is visual reversal? - in very clear water objects appear further away due to the particles in the water that resembles haze over great distance An hour after surfacing from a deep dive, a diver complains of fatigue and numbness in one shoulder.

As sound travels through air, which of the following changes occur: a. the molecules change their composition b. sound can only be transmitted through solid objects, so no changes occur to the air itself c. the air molecules travel from the speaker to the listener d. changes occur in air pressure - ANSWER d. changes occur in air pressure

Which of these statements is true regarding the way light travels? A. Sound travels faster than light. B. The speed of light is always the same regardless of the medium through which it travels. C. Light travels as both a wave and a particle. D. Light can not travel through a vacuum. - correct answer C. Light travels as both a wave and a particle. Light is a curiosity in that it acts as both a wave and a particle. It only changes direction via reflection (bouncing off of something) or ...

- greatest contributor to attenuation in tissues - Potential source of bio-effects (discussed later) acoustic speckle - noise resulting from the constructive and destructive interference of small sound wavelets -grainy appearance Amplitude - -For a wave or vibration, the maximum displacement on either side of the equilibrium (baseline) position. - positive amplitudes (above baseline) and negative amplitudes (below baseline) -units that are appropriate to the acoustic variable considered ...
