  1. The formula for WHEN to mask for bone conduction is

    2. Your answer:
    ABG (TE) >/= 10dB
    BC (TE) </= 0dB
    AC (TE) + BC (NTE) = AC (NTE) + BC (TE)
    AC - IA >/= BC (NTE)

  2. The formula for HOW MUCH initial masking to use is

    3. Your answer:
    55dB = IM
    AC (NTE) + OE = IM
    AC (NTE) = IM
    BC (NTE) + BC (TE) - IA = IM

  3. In this example, you need to mask for bone conduction: Right AC = 35, Left AC = 20, Unspecified BC = 0

    4. Your answer:
    TrueFalse

  4. In this example, you need to mask for bone conduction: Right AC = 70, Left AC = 65, Unspecified BC = 65

    5. Your answer:
    TrueFalse

  5. How much initial masking would you use in this example: Right AC = 30, Left AC = 65, Unspecified BC = 20.
