Comparison figure of 200-day old animal detection thresholds in the
current study (black lines) to pure tone ABR, CAP, and behavioral audiograms
(grey lines and symbols). The thresholds in the present study are expressed as
straight lines denoting the frequency band of a stimulus (males = black, females
= white). Zheng et al., 1999 (grey star,
329 day old) and Henry, 2004 (grey
triangle = males, 350 day old; inverted grey triangle = females, 350 days old)
measured pure tone auditory thresholds using ABRs. Ohlemiller et al., 2010 (grey square, 330 to 390 days old)
measured auditory thresholds using CAP recordings. Radziwon et al., 2009 (grey circle, 365–500 days
old) measured auditory thresholds for pure tones using operant conditioning
procedures.
