Kids make a lot of noise which is natural, and healthy. They need to play and bustle and burn some energy. But the loud noise can be harmful. This is where playmats come into play. A play mat is made of fabric and is a excellent noise dampener. A play-mat dampens the echo off the floor and dampens the noise toys make when dropped.
Just wanted to post as I just finished reading this post at Kids Headphones about Tinnitus and child hearing disorders.
