What is the typical audible frequency range at birth?

The typical audible frequency range at birth is indeed from 20 Hz to 20,000 Hz. This range indicates the capacity of a newborn’s auditory system to perceive sound frequencies. At birth, while some aspects of hearing may still be developing, infants generally possess a hearing range comparable to that of adults, which is approximately 20 Hz to 20 kHz (20,000 Hz). This ability allows them to respond to a wide variety of sounds, critical for their development and communication in the early stages of life.

In contrast, the other options provided do not accurately reflect the full spectrum of hearing that is typically observed at birth. For example, ranges that start at 10 Hz or are limited to upper frequencies below 20,000 Hz do not encompass the complete range of sounds that an infant can hear. Such limitations would suggest an incomplete or inaccurate portrayal of auditory capabilities at birth. Therefore, the choice reflecting the full range to 20,000 Hz is the most accurate representation of typical auditory capability at that stage.
