Lecture Introduction to linguistics: Phonetics (Part 2). In this chapter, students will be able to understand: Acoustic phonetics, sound waves, properties of sound waves, spectrograph, auditory phonetics, ear and brain, perception of sound. | PHONETICS (2) Dr. Ansa Hameed Previously .

An acoustic phonetician studies the waves of the sound produced with the help of special instruments. Acoustic Phonetics Acoustic phonetics investigates properties like the mean square and amplitude of a waveform, its duration, its fundamental frequency, or other properties of its frequency spectrum, and the relationship of these properties to other branches of phonetics (. articulatory or auditory phonetics), and to abstract linguistic concepts like phones, phrases, or utterances. Sound Waves Acoustic Phonetics Aspects of sound transmission Every sound, whether speech or non-speech, begins with a body of air set in vibration. It is this vibrating body of air which stimulates the nerves of the auditory system, thus transmitting sound waves to the inner ear. As a general rule, a forceful initiation will result in a relatively loud sound while a comparatively weak initiation will produce a quieter sound. ( Pendulum in motion is the example) Acoustic Phonetics Acoustic Phonetics Components of Study: Waves Sound is caused by a vibrating object, such as the tuning fork. When the arm of the tuning fork moves outward, it crowds the neighbouring air molecules together (raising the air pressure in the area). The crowded air molecules will tend to move into less crowded (lower pressure) areas, which causes those areas to get crowded, and so on. When the arm of the tuning fork moves inward, the neighbouring air molecules become less crowded (., it creates a partial vacuum).
