The image displays a line graph titled "Presbycusis" at the top center in blue text. The graph illustrates age-related hearing loss across different sound frequencies.

The horizontal axis (X-axis) represents Frequency measured in Hertz (Hz). It is labeled with "Low" on the left and "High" on the right. The specific frequency markers are 125, 250, 500, 1000, 2000, 4000, and 8000 Hz.

The vertical axis (Y-axis) represents Hearing loss measured in decibels (dB). The numbers on this axis are 20, 40, 60, 80, and 100, arranged from top to bottom. This indicates that a position lower on the graph corresponds to greater hearing loss.

There are four colored lines plotted on the grid, each representing a different age group, with labels on the right side of the graph:

1.  **Green Line (20 years):** Labeled "20 years" in green text. This line is at the very top of the chart, indicating the least amount of hearing loss. It stays relatively flat and high across all frequencies, hovering just above the 20 dB mark for low to mid-range frequencies. At the highest frequency (8000 Hz), it dips slightly but remains well above the other lines.

2.  **Yellow Line (40 years):** Labeled "40 years" in yellow text. This line starts near the 20 dB level. It stays relatively flat until about 1000 Hz, after which it begins a gradual downward slope. By the time it reaches 8000 Hz, it has dropped to approximately the 60 dB mark.

3.  **Orange Line (60 years):** Labeled "60 years" in orange text. This line starts slightly lower than the yellow line, around the 25-30 dB level. It remains flat until 1000 Hz and then drops more steeply. By 8000 Hz, it reaches a hearing loss of roughly 70 to 80 dB.

4.  **Red/Maroon Line (90 years):** Labeled "90 years" in red text. This line starts the lowest of all the groups at low frequencies, around the 30-35 dB level. It stays flat until 1000 Hz and then drops sharply. By 2000 Hz, it is near the 40 dB mark. The decline continues steeply, reaching the bottom of the graph at 100 dB by the time it hits 8000 Hz.

Overall, the graph demonstrates that as age increases (from green to red), hearing loss becomes more severe, particularly at higher frequencies (the right side of the graph).
