Based on the data from Tables 1 and 2, is human hearing equally sensitive across all frequencies? Based on your measurements, how much of a sensitivity variance (in decibels) is there from 125 Hz to 4...Based on the data from Tables 1 and 2, is human hearing equally sensitive across all frequencies? Based on your measurements, how much of a sensitivity variance (in decibels) is there from 125 Hz to 4 kHz? Based on the ISO standard graph, if this experiment had been repeated at a considerably lower average SPL, would the dB variances be identical to those measured here? Why/why not? What are some of the possible sources of error in this experiment?
