Sensation is the neurological process by which we become aware of our environment. You are at a crowded and noisy party and are trying to focus on the conversation you are having with a friend. Your ability to do this while mostly ignoring the flood of other information coming into your senses is known as:

Selective Attention

Explanation:

Selective attention is the process of fixing one's attention on a particular object or information while ignoring other surrounding distractions. Selective attention allows an individual focus on a relevant stimuli for a certain period of time while tuning out of an irrelevant stimuli in one's surrounding. In other words, selective attention is focusing on what matters and is important. It could be conscious or unconscious.

In the illustration above, the focus on the conversation (relevant stimulus) while ignoring the noisy party (irrelevant stimulus) is called selective attention.
