Death Awaits You
Yeah Arabs are loud as they come from a nomad culture but non-nomadic people such as the Niger-congo are also loud.It's because most were traditionally nomadic pastoralists so to communicate with each other from a distance they'd have to shout. Also they'd be shouting at their herd to guide them.
It's culturally embedded and probably will stick around for a while after somalis get rid of pastoralism.
