When children grow up and move out, sometimes the home may seem too quiet for the parents who remain.
Empty Nest Filler provides the sound of children as if they were still around. It can be used temporarily to help ease the transition, or for long term comfort. It may also be used by people who never
had children, but like the sound of them.
Some possible settings: rowdiness in the house, happy murmurings, faint outside playing, cereal slurpings, board game night, video game playing, teeth brushing, quieter reading to selves, carefree boasting,
It could be an app with controls to select the sound type, or a streaming service with different channels.
There are partially baked equivalents- sound effect and ambience libraries of kids playing, but they appear to be targeted toward commercial production use rather than consumer friendly products.
