Acoustic phonetics is a subfield of phonetics which deals with acoustic aspects of speech sounds acoustic phonetics is the study of physical transmission of speech sounds from the speaker to the listener thus, it is concerned with acoustics of speech: the spectro-temporal properties of the sound. Speech acoustics is between the studies of physiological phonetics and speech perception because speech acoustics is the science of the sounds and sound waves, which happens after the person articulates the sound (physiological phonetics), but happens before the listener perceives the sound (speech perception.
