How do you handle loud, meaningful family noises while trying to focus?
Understand what happens. Sound comes in contact with the ear which re recognise as such and such or voice of so and so. This creates a reaction which creates sensations to which you react with craving or aversion. In the above case you are reacting with aversion. When sound in the dominant input focus on the ear area for sensations. If the sound is very loud it might hurt the ear also but even in other cases when you practice you get some sensation. This has a mental reaction and thought proliferation. This gives arise to sensations in the head area. This should be your secondary focus. If you look closely you will see this creates vibration and sensation all over the body. This should be your tertiary focus. When you start you will not be able to even sense anything around the ear unless very intense but as you go on you will be able to see the vibration through out the body. This comes with practice.

What ever sensation you should not react to it.

Each time your mind gets distracted by the sound or any other sense input do the following:


Recognise the object of attention to which the mind has wandered away and note it without verbalisation or imagination (i.e., without creating mental fabrications): Sense input or mental chartering, etc.
There is a sensation tided to this object being in focus: it can be intellectual stimulation if it is an thought, some other sensation if the body, etc.
Analysing, mental reaction and through proliferation may have created sensations around your head and rest of the body. So note these sensations.
Bring back your mind to your chosen object of attention. This can be extended even when doing normal tasks.
Each stage try to calm the fabrications. Lesser fabrications more concentrated you get.
