Phonologyis the study of the sound system of languages. At one extreme, phonology is concerned with anatomy and physiology- the organs of speech and how we learn to use them. At another extreme, phonology shades into socio-linguistic as we consider social attitudes to features of sound such as accent and intonation. And part of the subject is concerned with finding objective standard ways of recording speech, and representing this symbolically.
