The purpose of this research was to illustrate and compare the differences in shapes of auditory filters of two individuals. The signal to noise ratio (P/N0) represented in Table 1, is a ratio of the power in the signal (P) over the spectrum level of noise (N0) which remained at 35 decibels except in the notch. The P/N0 is given in decibels and is derived by multiplying the log of this ratio by 20. Figure 1 displays the relationship between these variables and the width of the notch (f/fΔ) for both participants in the study. The figures indicate that as the P/N0 decreases the f/fΔ increase in a very similar trend for both participants in the study. While this trend was seen in both …show more content…
This was conducted by introducing three different age groups including ages six, ten and nineteen. Each age group included two individuals making a total of 6 study participants. Furthermore, the study also included three levels of a signal including 500 Hz, 1000 Hz and 3000 Hz therefore the current study could be attributed as presenting another level of signal for an older age group. However, when comparing the results from the current study to Irwin et al. (1986), it should be taken with caution as there was no demographic direct information provided for participants in the study nor were individuals in the study tested prior to participation to ensure that no previous hearing damage had
