## masking_auditoryfilter.jpg

The image is a graph that illustrates an auditory filter shape obtained using the notched-noise method. The x-axis represents frequency in kilohertz (kHz), ranging from 0.4 kHz to 1.6 kHz, while the y-axis represents relative response in decibels (dB). 

At the top of the image, there is a title that reads: "Figure 3.5. An example of an auditory filter shape obtained using the notched-noise method." Below this title, it states: "The filter was centred at 1 kHz. The response is plotted relative to the response at the tip, which was arbitrarily called 0 dB."

The graph shows a bell-shaped curve centered around 1 kHz on the x-axis. The peak of the curve corresponds to the point where the relative response is closest to zero dB (0 dB), indicating that this frequency has the highest sensitivity or responsiveness in the auditory filter.

There are no people, text, diagrams, numbers, figures, or any other elements present in the image aside from what was described above.
