When children are small, it seems that it's not all that difficult for most people to keep them quiet or calm them, as the case may be.
That being said, there are many kids out of control because, among a myriad of other reasons, parents want to be friends first and parents later.
But that is another issue.
If you have reached a point where the noise is out of control and it is interfering with other members of the household, sound proofing a room may be the answer to bring peace and harmony to the family.
A few things can be done easily and without too much expense.
First, consider volume control.
If the offending media player makes the floor vibrate, turn it off.
Yes, off.
If this creates more trouble than its worth, there are other options, but they require more effort.
Foam insulation board can be bought in a number of different thicknesses.
It is available at home improvement stores and large hardware stores.
If the room that has the most noise has common walls with the other rooms, try rearranging the furniture.
For instance, sound can be absorbed by dressers in bedrooms.
If this is not enough foam, board can be placed behind the furniture and out of sight to help absorb more of the sound.
The foam can be cut to measure with a box cutter.
Adjacent closets can also have foam placed along the inner wall to help absorb more sound.
Extra blankets can be used to cover the foam and will also increase the amount of noise absorption material.
Extra pillows can be stored in the closet also and will also help serve in absorbing the sound while in storage.
If none of these options work, check out a sale on ear plugs in the pharmacy section of your local drugstore and stock up.
