RCDD TEST QUESTIONS (TOPIC 1 - TOPIC 7) WITH COMPLETE SOLUTIONS. If the input signal power to a communication system is 1 W and the output power is 1 mW, the system attenuation is: A. 3 dB B. 20 dB C. 30 dB D. 40 dB E. 1000 dB C. 30 dB The signal at the input to a balanced twisted pair cable is 10 mW. The cable is 1000 feet long and has an attenuation of 1 dB per 100 feet. This cable is connected to the input of a receiver. The noise level at the input to the receiver is 1 microwatt....

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...

In general, mold modifications are as follows: - Venting affects lows, damping the midrange and horn effects boost highs. Basic verification involves: - checking MCL and UCL in quiet and noise. Sound field is - a controlled environment The configuration and height of the tympanogram can be a factor in deciding the proper matrix for the fitting of a hearing aid: - A high Type A tells us to decrease the output by 2-3 dB You cannot use feedback checks when - checking the telephone coil ...
