What is the auditory learning style?
Auditory learning is a style of learning in which an individual learns more efficiently by listening.

A person who is an auditory learner relies on speaking and listening as their primary way of learning.
Many auditory learners may experience challenges when they receive instructions or information in written form but can clearly understand them when the information is auditory. These individuals are typically good listeners and can easily remember information that has been spoken.
