I was thinking about a soundproof ear protector which is really more efficient than typical ones. Typical ear protectors are big and not really efficient. By using better soundproof materials and remodeling them we can achieve smaller and more efficient ear protectors. It is not possible to sleep in bed with those giant ear protectors on, but with new small one you can experience a noiseless night.
