Sound diffraction is the bending and spreading of sound waves around obstacles and through openings, a phenomenon that enables us to hear sounds even when the source is not directly in the line of sight. This behavior is influenced by the wavelength of the sound relative to the size of the obstacle or aperture, being more pronounced in sounds with longer wavelengths such as low-frequency sounds.

Line of sight refers to the straight path that light or an electromagnetic wave travels from a source to an observer, without any obstruction. It is crucial in fields such as telecommunications, astronomy, and vision, where clear, unobstructed paths are necessary for accurate transmission and reception of signals or information.

Aperture refers to the opening in a camera lens through which light enters to expose the film or image sensor. It directly affects the depth of field and the amount of light that reaches the sensor, influencing both exposure and the sharpness of an image's background and foreground.
