## Line Graph: Comparison of Multi-Harmonics (500Hz) and White Noise Attenuation
### Overview
The graph compares the attenuation of two noise types—Multi-Harmonics (500Hz) and White Noise—as a function of the number of plane waves. Both lines show a downward trend in Gain (GoA) in decibels (dB), but with distinct rates of decline.
### Components/Axes
- **X-axis**: "Number of Plane Waves" (0–20, increments of 2).
- **Y-axis**: "GoA (dB)" (-30 to 0, increments of 5).
- **Legend**: Located in the top-right corner.
- Blue line with open circles: "Multi-Harmonics (500Hz)".
- Red line with star markers: "White Noise".
### Detailed Analysis
1. **Multi-Harmonics (500Hz)**:
- Starts at approximately **-5 dB** at 1 plane wave.
- Declines steeply to **-25 dB** by 15 plane waves.
- Stabilizes near **-25 dB** for 17–20 plane waves.
- Data points: (1, -5), (3, -10), (5, -15), (7, -20), (9, -22), (11, -24), (13, -25), (15, -25), (17, -25), (19, -25), (20, -25).
2. **White Noise**:
- Begins at **-5 dB** at 1 plane wave.
- Declines gradually to **-25 dB** at 20 plane waves.
- Data points: (1, -5), (3, -8), (5, -10), (7, -12), (9, -14), (11, -16), (13, -18), (15, -20), (17, -22), (19, -24), (20, -25).
### Key Observations
- **Steeper Initial Decline**: Multi-Harmonics attenuates faster than White Noise in the early range (1–10 plane waves).
- **Convergence at High Plane Waves**: Both noise types stabilize near -25 dB beyond 15 plane waves.
- **Red Line Consistency**: White Noise maintains a nearly linear decline until the final data point.
### Interpretation
The graph demonstrates that Multi-Harmonics (500Hz) noise is more sensitive to the number of plane waves, exhibiting rapid attenuation initially. This suggests that Multi-Harmonics may be more susceptible to destructive interference or cancellation effects when multiple plane waves are introduced. In contrast, White Noise attenuates more gradually, indicating a less pronounced dependency on plane wave count. The convergence at higher plane wave counts implies diminishing returns in noise reduction for both types beyond a critical threshold (~15 plane waves). This could inform noise mitigation strategies in systems where plane wave configurations are adjustable.
