It does limit the volume to 54db so I think the 1812 Overture would be kind of flat, and would limit post-partum fun.
You could still play that piece from Carmina Burana, "O Fortuna", the one used in the movie Excalibur when King Arthur rides out and springtime follows his army across the lands. Truly one of the great epic music-to-action edits of the color-cinema era!
