# 7.6: Questions


1. Based on the data from Tables 1 and 2, is human hearing equally sensitive across all frequencies?

2. Based on your measurements, how much of a sensitivity variance (in decibels) is there from 125 Hz to 4 kHz?

3. 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?

4. What are some of the possible sources of error in this experiment?
