I'll add my voice to the chorus of BOOOS to NBC for their terrible audio coverage of the curling matches.
The crowd noises, music, announcements from the stadium speakers, and the voices of the skippers are all very loud.
However the commentary is so quiet and soft that I cannot understand a single word. It is English which is my native language. Its volume is low. Not a single world can I understand !
F--- is the richly deserved grade for the audio technicians of NBC: FAIL !!!!!!
