Figure 1 Effect of various types of noises on dominant frequency in the subjects of age below 50 (n = 12) and above 50 (n = 9). Base-, baseline; Conv-, conversation babble; Hosp-, hospital noise; Traf-, traffic noise. One-way RM ANOVA vs individual baseline, no statistical significance was observed.

Figure 2 Effect of various types of noises on dominant power (DP) in the subjects of age below 50 (n = 12) and above 50 (n = 9). Base-, baseline; Conv-, conversation babble; Hosp-, hospital noise; Traf-, traffic noise. One-way RM ANOVA vs individual baseline, no significance was observed. The baseline DP of the older group (age > 50 yr) was significantly lower than that of the younger group (age < 50 yr): aP < 0.05, Student’s t test.
