In Anapasati suttaLord budda tells,
There is the case where a monk, having gone to the wilderness, to the shade of a tree, or to an empty building, sits down folding his legs crosswise, holding his body erect, and setting mindfulness to the fore.1 Always mindful, he breathes in; mindful he breathes out.
Here we can take our room or meditating place while it's empty of sounds as the empty building,So in night and morning time is the best time for that because there is less noise in that time..Someone feels better in night before go to sleep and someone may feels better in morning if feels tired in night before sleep..So this can be applied for other meditations too,You can choose better time between before sleep and just after wake up
