Final answer:
Assessing hearing acuity in a 6-month-old child is typically done by watching for head turning when the child's name is called, as this relies on natural behavioral cues indicative of auditory recognition.
Step-by-step explanation:
When assessing hearing acuity in a 6-month-old child, the examiner would observe for head turning when saying the child's name. This age-appropriate technique is ideal for infants, as audiometers are typically not used until the child is older and able to respond reliably to auditory stimuli in a test environment. Watching a child of this age for head-turning responds to understanding that by six months, infants have developed significant auditory abilities and may show recognition to familiar sounds such as their name being called. This practical observation takes advantage of an infant's natural response to turn toward familiar voices or sounds.
When assessing hearing acuity in a 6 month old child, the examiner would watch for head turning when saying the child's name. At this age, a child should be able to turn their head toward the source of a sound, such as when their name is spoken. This response indicates that the child is able to hear and locate sounds, which is an important aspect of assessing hearing acuity in infants. Using an audiometer or testing the startle reflex are not appropriate methods for assessing hearing in a child of this age.
