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...

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...
