Listening is often confused with hearing. While hearing is a biological process that can be scientifically explained, listening is a psychological phenomenon. Listening is psychological because it requires internal contextual contemplation of the sound waves. This internalization requires the use of social connotation which implies bias. According to philosopher Roland Barthes, listening can be understood on three levels: alerting, deciphering, and an understanding of how the sound is produced and how the sound affects the listener.
