Yes, the proper term is 'ululation'! Renamed is the winner of a large box of kudos from the Hun.
Don't spend them all in one place.
I came across the word in the following story:
[b]Egyptian actress gets 10 years for torturing maid[/b]
CAIRO (Reuters) - An Egyptian court jailed an actress for 10 years with hard labour on Wednesday for abusing and torturing her two maids, security sources said.
Wafaa Mekki and her mother were found guilty of beating and torturing Mekki's two maids, 15-year-old Marwa Abul Hamid and her 17-year-old sister, Hanady. Mekki's mother got a one-year prison sentence with hard labour.

Imagine the shame and humiliation of it all - being ululated upon in public!
And Hannah_Reitsch is amazing, as well, for knowing the word in Arabic was "zaghareet".
