If i am in the fard salah and my brother is humming, or making loud noises like hitting his desk or shouting loudly as he does not see me praying salah in the same room, what is permissible for me to do, can I stop this by telling him or snaping my fingers etc, or do I continue salah with less focus

Ustadh AbdulAziz al-Haqqan

Say out loud, Subhanallah.
