Kathy-Schmidt Method

The Kathy-Schmidt method was developed in the 1920s by Karl Schmidt and his wife Kathleen Kathy. The essence of the method is that in it children react to the level of noise that they hear from outside. This method is ideal for measuring sound volume.

The Kathy-Schmidt method is based on the idea that as one child perceives sounds of different frequencies, the second begins to perceive other sounds that this level produces. The method is based on the assertion that children’s reactions to a particular sound depend on their physical condition and sensitivity. This means that the volume of the sound affects the child's ability to perceive different sounds.

This method uses a special electronic system to record children's reactions. This system documents the extent to which the child responds to external sounds. The output is a spectrum of sounds. Because this method can record changes throughout a child's development, it enables educators, parents and neuroscientists to determine how the environment influences their children's development. Using this system, you can determine where it is best to place sound advertising, TV and other loud devices so as not to affect the child’s health.
