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.
