摘要
The risk of disturbance from children's cries is reduced if the child is subjected to mechanical vibration. This is applied to the child's place of rest by the use of a motor with imbalance. The environmental inconvenience caused by the children's cry is eliminated usually by a vibration frequency which is disturbing in itself but which is attenuated in a known way at the place of rest's contacts with the surroundings. An automatic device for starting when the child cries can be applied.
