what are the two major purposes for contralateral recording
channels?
A) 1) validating white noise masking is absent at appropriate
intensity
2) improved identification of Wave I differentiated from wave IV
B) 1) validating white noise masking is being presented at
appropriate intensity
2) improved identification of Wave II differentiated from wave III
C) 1) validating good impedance
2) improved identification of Wave IV differentiated from wave V
D) 1) validating white noise masking is being presented at
appropriate intensity
2) improved identification of Wave V differentiated from wave IV
Ans: D) 1) validating white noise masking is being presented at
appropriate intensity
2) improved identification of Wave V differentiated from wave IV
what does white noise masking prevent? Ans: bone conducted
crossover responses
