Study Notes

Development of Auditory Perception in Infants

Sound is composed of waves, and the higher the frequency, the higher the pitch, measured in Hertz (Hz) or as notes on a scale.
Melody is a sequence of pitches with a logical sense, made up of intervals and a contour, and is important for conveying meaning and emotion in speech.
Beat refers to the perception of evenly spaced points in a sequence and is measured in beats per minute (bpm), which determines the tempo of music.
Rhythm is the full pattern of temporal intervals in a sequence.
Timbre is the tonal quality of a sound, important for language perception and allowing the distinction between types of sounds.
The fetus in the aquatic environment is primarily exposed to low-frequency sounds due to the attenuation of high-frequency and loud sounds by fluid and tissue.
The development of auditory perception in infants occurs gradually, with responsiveness to sound starting at around 20 weeks of pregnancy.
Basic auditory abilities, such as localization, identification, and discrimination, are already developed at birth and continue to develop up to 2 years after birth.
Newborns can discriminate a wide range of pitches, but this range narrows as they get older due to perceptual narrowing, influenced by attachment and language development.
Pre-term infants in the neonatal intensive care unit (NICU) are overexposed to high-frequency sounds and underexposed to low-frequency sounds, which can have adverse effects on their auditory and language development.
A 2015 study showed that exposure to realistic uterine soundscapes can evoke auditory plasticity in preterm infants, leading to faster development in the auditory cortex.
Melody discrimination ability reaches adult levels at around 10-11 years old, and singing ability peaks at around 10-11 years old.
