Geometric mean frequency (kHz)

Figure 76.5 Relationships between DPOAE amplitude (dB SPL) and geometric mean frequencies (5.6-44.8 kHz) in three age groups of CBA mice, including the mean noise floor across the testing frequencies. A. Young adult group—similar amplitudes for both sexes. B. Middle-aged group—the females presented with higher DPOAE amplitude than males. The findings were confirmed with a two-way ANOVA (F=11.9, P< 0.001). C. Old group—the DPOAE amplitudes for females were also higher than those for males with confirmation by the two-way ANOVA (F= 5.91, P<0.05). Note that the sex difference was smaller than for the middle-aged group (1B). F-DP = Female DPOAE; F-NF= Female noise floor; M-DP= Male DPOAE; and M-NF= Male noise floor. From Guimaraes et al.

Blood Pressure Health

Your heart pumps blood throughout your body using a network of tubing called arteries and capillaries which return the blood back to your heart via your veins. Blood pressure is the force of the blood pushing against the walls of your arteries as your heart beats.Learn more...
