The image is a diagram illustrating a coordinate system used to define the position of sounds relative to the head. The diagram includes various planes and angles that help in understanding how sound sources are located around an individual's head.

At the center of the diagram, there is a human head depicted with its face oriented towards the right side of the image. The head is shown from a slightly elevated angle, providing a clear view of both the front and top parts of the head. The ears are positioned on either side of the head, and the eyes are not detailed but implied by the outline.

The diagram includes several planes:
- **Frontal Plane**: This plane runs horizontally through the center of the head, dividing it into front and back sections.
- **Median Plane**: This vertical plane runs down the middle of the head, dividing it into left and right sides. It is labeled as "median plane."
- **Horizontal Plane**: This plane is shown below the frontal plane and above the median plane, running horizontally through the center of the head.

The diagram also includes angles to describe the position of a sound source relative to the head:
- **Azimuth (θ)**: This angle describes the horizontal direction from forward to backward. It ranges from 0° at the front (forward) to 180° at the back (backward).
- **Elevation (δ)**: This angle describes the vertical direction from downward to upward, with positive values for upward directions and negative values for downward directions.

The diagram also includes a coordinate system that uses these angles:
- The azimuth is represented by an angle θ.
- The elevation is represented by an angle δ.
- The distance of the sound source from the head is denoted by r.

There are dashed lines extending from the center of the head to represent different positions in space, illustrating how sounds can be located at various angles and distances. These lines help visualize the concept that a sound's position relative to the head can be described using these three parameters: azimuth (θ), elevation (δ), and distance (r).

The diagram is labeled as "Figure 7.1" from Moore 2007, "Cochlear Hearing Loss," which indicates its source and context within a larger discussion on hearing loss and sound localization.
