Idea for new product 4 Sound proof baby cover 防音カバー 赤ちゃん用

I have had the idea for new products for quite some time. With limit on my skill I cannot make them thus I would like to share with those who can make them real products.

Idea 4. Sound proof baby cover:

As the title suggests, this product is basically a sound proof material to cover a crying baby with a structure to make sure the baby has enough space and air to breathe and it must be somehow so transparent for parents to see the baby inside.  And also the sound proof function should not be too strong thus parents can still hear the baby.

Babies cannot talk so they cry instead of talking. It is a very important way of communication. Yet, you may find it difficult when babes do not stop crying in public or when your partner is trying to sleep.

This product can also work for baby to have a silent place to sleep by shutting down the sound from outside. You could talk to others, listen to radio or watch TV beside your baby.

This product should have two layers so the user can "adjust" the volume by choosing to use one or two layers.

It is important to note that this product should not be used when parents are sleeping. Parents need to be able to catch the slightest sign in the sound of baby to find any possible problem the baby has.  This product is only to serve the convenience of the parents or anybody taking care of babies in a supplemental way. Again, this shall never prevent parents noticing any problem the babies may have.

This should not be that difficult for companies to make. But I cannot make it...

I have too many ideas ( many of them might be really stupid or already on the market without my knowing it though). I will share more ideas with you soon.
