Table 4.
Results of post hoc analyses (Tukey tests) indicating the ages (in weeks) at which infant admittance magnitude (∣Y∣) pressure differences (∣Y∣ at a given static ear-canal pressure minus ∣Y∣ at TPP) were significantly different from adults (α=0.05). A blank space indicates the lack of astatistically significant difference between any of the infant groups and the adult group.
