Here's the science all over again - up-to-date facts on screams, in order to engage with in the quest for truth.
Traced and verified sources.

Human screams have unique auditory qualities. Human screams of terror are extremely effective at conveying distress and alarm, but exactly why has not been known. Now David Poeppel of New York University and his colleagues have looked beyond the measurements of sound pressure and frequency, which merely indicate that screams are louder and higher pitched than normal speech, and focused on their modulation power spectrum. They found that while typical speech changes less than 5 Hz, screams fluctuate rapidly between 30 Hz and 150 Hz. Those fluctuations give the sound a certain roughness that is unique in human vocalizations. Based on the ranking of volunteers who listened to various terror screams, the researchers found that the more screams fluctuate in volume, the scarier they are perceived to be. Thats because screams activate both the auditory cortex and the amygdala, the part of the brain attuned to emotional reactions; regular speech triggers just the auditory cortex. The natural acoustic roughness of human terror screams has been effectively mimicked in artificial systems, such as house and car alarms, which is what makes them so super annoying and hard to miss, says Poeppel.

"But whats surprising in all this is that the entire range of mens and womens voices remains between about 65 Hz for a male with a very deep bass voice to the highest note of a
female coloratura soprano, just above 1,000 Hz, at 1,280 Hz. (A female high-pitched scream can go quite a bit higher, to around 3,000 Hz.)
So lets imagine a male high voice gets to 1000Hz, that leaves us with a female scream still 2000 hz away.

These, as we know are from an earlier thread.
Oscar would not have been able to reproduce these characteristics ever.
You know though - when I joined WS, I learned stuff from other posters, isn't that odd.
This is getting silly, isn't it.
Maybe, I should contact correctional services and suggest for Oscar - female-only OPERA company.
