aaert equipment quizzes with 100% correct solutions sound - Correct Answer ️️ -is defined as vibrations that can be perceived microphone - Correct Answer ️️ -converts the acoustical energy that is sound into an electrical signal that can be delivered to either an analog or a digital device analog and digital - Correct Answer ️️ -recordings start the same way; with sound digital mixer or A/D converter - Correct Answer ️️ -to change the analog signal to a digital signal it will need to pass through an analog to digital converter, commonly referred to as a sample rate (44.1 khz, 48 khz,etc.) bit rate (usually 16 or 24 bits) - Correct Answer ️️ -the two most important factors in the quality of the new digital audio are low sampling rate - Correct Answer ️️ -approximation high sampling rate - Correct Answer ️️ -smooth the bit rate - Correct Answer ️️ -represents the amount of information, or detail that is stored per unit of time of a recording digital court reporting programs - Correct Answer ️️ -sample at a rate fast enough, thousands of times a second, so speech sounds are smooth and correctly represented when selecting the microphones that you will use there are several variables: these variables include - Correct Answer ️️ -Microphone type (dynamic or condenser) microphone pick-up pattern microphone size and stands microphone cost for the purpose of digital reporting, AAERT recommends that you slect - Correct Answer ️️ -dynamic, condenser, or a combination of dynamic and condenser microphones. Both of these microphone types work in a unique way but can generate a high quality audio reproduction dynamic microphones - Correct Answer ️️ -(also called "moving coil" microphones) are made up of a diaphragm, a coil, and a magnet. As acoustical energy hits against the diaphragm, which is a flat plate at the front of the microphone, it causes the coil that is attached to it to move back and forth over top of the magnet . they are bulky condenser microphone - Correct Answer ️️ -consists of a front plate (diaphragm), back plate, and a 48 volt power source. The front and back plate together create a capacitor. wider assortment of shapes and sizes. one type commonly used is a gooseneck microphone phantom power - Correct Answer ️️ -when acoustical energy hits the front plate of the capacitor, the distance between the front and back plate changes. the gap between these two plates is electrically charged. this charge is created by either an internal battery source or an external power source referred to as .. aaert does not recommend: - Correct Answer ️️ -the use of batteries as the supply of this charge. if a battery would die during use, you could have a gap in your re
