RIM 3010 EXAM 2 STUDY GUIDE 2023 UPDATED. simple sound system - CORRECT ANSWER-microphone— preamplifier—console—amplifier—speaker Transducer - CORRECT ANSWER-a device that changes one type of energy (electric, acoustic, etc.) into another form of energy. passive loudspeaker - CORRECT ANSWER-a loudspeaker that is powered externally. active loudspeaker - CORRECT ANSWER-a loudspeaker that is powered internally. crossover network - CORRECT ANSWER-electronic equipment that sends high-frequency sound to tweeters and low to woofers. crossover frequency - CORRECT ANSWER-the sound frequency point at which sounds after that will be greatly reduced, effectively blocking them. woofer - CORRECT ANSWER-a loudspeaker designed to reproduce low frequencies. tweeter - CORRECT ANSWER-small speakers that reproduce high sounds. two-way system loudspeaker - CORRECT ANSWER-a loudspeaker system with one crossover network, and two drivers. three-way system loudspeaker - CORRECT ANSWER-a loudspeaker system with two crossover networks, and three drivers. anechoic chamber - CORRECT ANSWER-a room that prevents all reflected sound through the dissipation or absorption of sound waves. frequency response - CORRECT ANSWER-variation in output level or sensitivity off a microphone over its usable frequency range, sometimes referred to as "colorations". sweet spot - CORRECT ANSWER-ideal listening position based on your speakers and room layout (gives an optimal representation of the signal in a room). optimal speaker positioning shape - CORRECT ANSWER-equilateral triangle. far-field monitoring (Mains) - CORRECT ANSWER-monitoring with loudspeakers placed far from the operator, allow audio to be heard in the room, taking advantage of room acoustics to impact the sound. near-field monitoring - CORRECT ANSWER-monitoring with loudspeakers placed close to the operator, usually on or just behind the console's meter bridge, to reduce interference from control room acoustics at the monitoring position. calibration - CORRECT ANSWER-any procedure used to evaluate the accuracy of a measurement system and, when sources of error are found, to use that information to correct or improve the measuring system. spectrum analyzer - CORRECT ANSWER-a device that derives a frequency spectrum from a complex signal. real-time analyzer (RTA) - CORRECT ANSWER-a device that shows the total energy present at all audible frequencies on an instantaneous basis. noise cancelling headphones - CORRECT ANSWER-utilize destructive interference to neutralize noisy situations. in-ear monitoring - CORRECT ANSWER-used by musicians in live concerts to replace stage monitors. over the ear headphones - CORRECT ANSWER-headphones that fit over the user's ears. open back headphones - CORRECT ANSWER-allow air to pass through their ear cups to the speaker element, not great if you don't want others to hear what you're listening to. moving-coil microphone - CORRECT ANSWER-a coil of wire attached to a receiving mechanism suspended within a magnetic field. ribbon microphone - CORRECT ANSWER-similar to a dynamic microphone, but uses a corrugated ribbon of metal foil fastened between 2 clamps as a diaphragm. phantom power (P48, 48V) - CORRECT ANSWER-provides the fixed charge for the capacitor plates on a condenser microphone. capacitor/condenser microphone - CORRECT ANSWER-a microphone that transduces acoustic energy into electric energy through a capacitor that requires an external power source. dynamic microphone - CORRECT ANSWER-a rugged, durable microphone, uses small coil that moves within a magnetic field to produce a signal. transient - CORRECT ANSWER-a high amplitude, short-duration sound at the beginning of a waveform that occurs in phenomena such as musical sounds, noises or speech. polar response pattern - CORRECT ANSWER-the graph of a microphone's directional characteristics as seen from above. The graph indicates response over a 360-degree circumference in a series of concentric circles, each representing a loss in level (dB) as the circles move inward toward the center. omnidirectional - CORRECT ANSWER-pickup pattern of a microphone that can hear equally well from all directions. bidirectional/figure-8/pressure gradient - CORRECT ANSWER-pickup pattern of a microphone that can hear equally well in opposite directions. unidirectional - CORRECT ANSWER-pickup pattern of a microphone that can hear equally well in one direction. cardioid - CORRECT ANSWER-heart-shaped pickup pattern of a unidirectional microphone. sensitivity - CORRECT ANSWER-the measure of the microphone's ability for converting acoustic pressure into an electric voltage. self-noise - CORRECT ANSWER-electrical noise or hiss a microphone produces. signal-to-noise ratio (S/N) - CORRECT ANSWER-the proportion of noise to the strength of a signal (how far away is my signal from hearing the audible noise of this electrical device? every piece of electronic equipment makes some kind of noise, and you have to be able to overcome that noise (hiss/hum/buzz) with your signal). proximity effect - CORRECT ANSWER-as we get closer to a microphone diaphragm, low frequencies are going to be more present/pronounced (by-product of this is the microphone's ability to control plosives is lessened). plosive - CORRECT ANSWER-"popping" sounds, like P's and B's. high-pass filter (HPF) - CORRECT ANSWER-resonator that transmits acoustic energy above a specific lower cutoff frequency (lets high frequencies pass through by reducing the low frequencies). pad - CORRECT ANSWER-(attenuator) one or two step volume control on a microphone, deals with attenuation, makes sure that the microphone does not distort. windscreen - CORRECT ANSWER-a covering, usually foam, placed over a mic to reduce the rumble or flapping sound created when wind blows across the mic. pop filter - CORRECT ANSWER-a wire-mesh screen attached to the front of a mic that reduces breath pops and sudden air blasts.
