Across Acoustics

Even though the vocal tract is the same regardless of a child’s sex before puberty, researchers have found time and again that adults can perceive gender differences in speech as early as four years of age. In this episode, we talk to Priscilla Fung, lead author of “The development of gendered speech in children: Insights from adult L1 and L2 perceptions,” which appeared in the January 2021 issue...

How does a piano string compare to an ideal physicist’s string? Are there equations that describe the sound a recorder produces? Can the quality of an instrument be quantified?
