## masking_offfrequency.jpg

The image is a graph that illustrates sound level (in decibels, dB) on the vertical axis and frequency (in Hertz, Hz) on the horizontal axis. The graph shows two distinct bars representing different elements: "Masker" and "Signal."

1. **Masker**: This bar is located towards the left side of the graph and extends upwards to a certain height on the sound level axis. It represents a masking noise that covers or obscures another sound, making it difficult to hear.

2. **Signal**: This bar is positioned further to the right on the frequency axis but does not extend as high as the "Masker" bar on the sound level axis. It indicates a signal sound that might be present in an environment where masking noise is also occurring.

The graph visually demonstrates how the masker, which has a higher sound level at lower frequencies, can effectively cover or mask the signal, which has a lower sound level and occurs at a different frequency. This concept is often used to explain why certain sounds are harder to hear when there is background noise in an environment.
