Singapore also can hear (?)

This evening, we were watching the Singapore series 'Reunion Dinner', which is shown Mondays-Fridays at 7pm-8pm on Astro 301

Coincidentally, when the iman/uztaz (or whatever names they call themselves) started the Isyak prayer, there was a scene where the lady was closing the windows of her house.

My daughter commented :-
'See, she can also hear the surau's prayer in Singapore, that's why she is closing all her windows.'
