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 recording and you would need to interrupt the event you are reporting to fix this problem most digital mixers and A/D converters - Correct Answer ️️ -act as a phantom power supply source. the changes in electrical energy between these two plates will travel through the wires of the microphone and eventually reach your digital mixer or A/D converter. essentially the biggest difference between these microphone types is the way by which acoustical energy is transformed into electrical energy: one assisted by an electrical source and the other by a magnet. both are capable of facilitating a quality audio recording and are recommended for use in the field of digital reporting pick-up pattern - Correct Answer ️️ -is the set path in which a microphone will intercept sound cardioid pick-up pattern - Correct Answer ️️ -(also known as unidirectional) meaning heart shaped, is a heart shaped pattern which reaches out from the diaphragm of a microphone. This pick-up pattern is beneficial for capturing a SINGLE voice located in front of a microphone while rejecting additional ambient room sound omnidirectional pick-up pattern - Correct Answer ️️ -is the combination of the word omni meaning "ALL" and direction. It intercepts sound from all directions from its placement. meaning it captures sound equally from all directions. Its beneficial for capturing multiple voices using only one microphone low profile boundary microphone - Correct Answer ️️ -these microphones lay flat on a desk or table and are commonly no more than inch or two thick. one important note about these microphones is that you must be aware of its location so that it does not get covered up. out of sight, out of mind should not be the approach for these microphones lavalier microphone - Correct Answer ️️ -this is an extremely small condenser microphone that attaches directly to the speaker. These microphones are extremely useful when the environment does not offer an opportunity to place a microphone in front of a speaker. they can be both wired and wireless. the use of these mics requires the use of batteries and should be used with extreme caution XLR connectors - Correct Answer ️️ -are the most common microphone connectors. ______ cables, commonly refered to as microphone cables have a male end and a female end. without these cables, it can be impossible to record from your mics. It is recommended that you always have spare cables on hand. if cable is pinched, sliced, or kinked, you may hear static or you may not hear anything at all the male end of the connector - Correct Answer ️️ -has three pins on the inside which seat with a female XLR jack. This connection commonly occurs at a mixer the female end connector - Correct Answer ️️ -consists of three sockets which allow the male end to connect. In most cases, mics have a male connection permanently installed in them which the female end of the cable connects with. one exception to note would be a microphone that is hard wired digital mixer - Correct Answer ️️ -refers to a device that takes the analog connection of the mics, converts that analog signal to a digital signal, and transports that signal to a computer. they are sometimes referred to as audio interfaces in the world of digital court reporting. input types - Correct Answer ️️ -Mic., instrument, and line. For the purpose of digital court reporting, we are interested in the mic input. This will usually be an XLR connection, but it can also be a TRS input. Microphone preamps - Correct Answer ️️ -any mic inpu
