Wordless attention-getter (4)

Ross

I believe the answer is:

psst

(Other definitions for psst that I've seen before include "Notice me" , "Sound to call quietly" , "Quiet attention-seeker" , "Sibilant sound to get someone's attention" , "Call to attract attention" .)

I've seen this clue in the Universal.
