Powerful Lady Talks Unusually

“So Ms. Abramson’s 20–25 Hz phrase-final amplitude modulation of her 140–145 Hz fundamental frequency is heard as a sort of superimposed infrasound. (Technically “infrasound” should be below 20 Hz, but this is close.) 140 Hz is not unusually low for the bottom of an adult woman’s pitch range — but 20–25 Hz is low for humans of any kind…. [T]his is first time that I’ve ever seen such a large-factor amplitude modulation so stably superimposed on a speaker’s sequence of pitch pulses.”
