IHS ILE Exam (study for the written hearing aid dealers/fitters exam) What does decreasing the compression ratio do, and when would you use this? - ANS-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? - ANS-Soft sound gain is unaltered, but gain for moderate/loud sounds is lowered. Most often...

Kent CNIM Review - ABR List the sound intensity scales - correct answer dB SPL dB HL dB nHL dB SL dB peSPL What is dB SPL? - correct answer SPL = sound pressure level Sound intensity based on a physical measure of sound pressure relative to atmospheric pressure. What is the equation for dB SPL? - correct answer dB SPL = 20log (Psound / Patm) When Psound = Patm, this is 0dB SPL To go up 20 dB SPL how much should pressure be increased? - correct answer 10x To go up 40 d...

ARDMS SPI STUDY GUIDE CERTIFICATION EXAM Q&A In soft tissue, if the frequency of a wave is increased the Propagation Speed (PS) will... - CORRECT ANSWER-Remain the Same because stiffness and density affect Propagation Speed. What is the audible range? - CORRECT ANSWER-20-20,000Hz >20,000Hz=Ultrasound Frequency is measured in - CORRECT ANSWER-Hertz (Hz) is Cycles per Second Not affected by sonographer Increase Frequency; Decrease Depth A period is the length of time it takes f...

What is the BEST way to determine how reverberant a space is? - Clap your hands and listen for an echo - Ask the client if anyone has complained that the room is too noisy - Use an RT60 meter - Use a DB SPL meter - Use an RT60 meter - feedback from the benchmarking site visit - end-user descriptions of how the room will be utilized When establishing initial contact with a client, try to develop a relationship early on with the: - Chief operating officer - Information technology manager ...

On Friday afternoons. - As part of regular system maintenance, when is the BEST time to update device firmware? -On Friday afternoons. -As soon as updates are available. -Device firmware should never be updated after system sign-off. -After coordination with the client, and when the system will be available for an extended period of time Design phase - When working with a client to design an AV solution for a new conference center, the client requests a detailed budget for the equipment a...

Logarithm - is the exponent of base 10 that equals the value of a number In decibel formulas how should values be logically arranged when comparing two numbers (V1 / V2) - If you expect a gain, place the higher number first. If you expect a loss, place the smaller number first. Explain negative decibel values - measurement just means "less than before," or in this case, "less than the reference level. It does not mean the basic unit it represents has a negative value Decibel - describes...

- You've been dispatched to address an installation in which a ceiling mounted projector is overheating. What is the FIRST step you might take in troubleshooting this issue? Verify that the brightness is set within parameters as established by the commissioning documentation Check the air filters to ensure they're free of all dust and clean if necessary Turn the project upside down and install with a reverse mirror mount to allow better airflow Verify that the correct Wattage of lamp was i...
