Signal to noise ratio Study guides, Class notes & Summaries

The four things needed for good SI - limited distortion limited feedback Direct signal which is louder than competing sound Direct signal to audience in reverberant room Elements of electronic sound systems - microphone, amplifier, electronic controls, and loudspeaker Central sound system - cluster of speakers over sound source Distributed sound system - An array of speakers all over the room Seat integrated sound system - has speakers built into the seats Microphone - A device that con...

What does decreasing the compression ratio do, and when would you use this? - Answer-Soft sound amplification is unaltered, but gain is increased for moderate/loud sounds. Most often used if a PT complains loud sounds aren't loud enough or sound "mushy" What does increasing the compression ratio do, and when would you use this? - Answer-Soft sound gain is unaltered, but gain for moderate/loud sounds is lowered. Most often used if a PT complains loud/moderate sounds are too loud or backgrou...
