Cochlear implant. Distinguishing sound frequencies电脑版

The goal of the game is to teach a child to distinguish sounds in frequency. Sounds are low-frequency (low - for example, a drum), mid-frequency and high-frequency (high - a whistle, a bell). Most non-speech and speech sounds contain different frequencies, but they are dominated by sounds of certain frequencies. The child should hear sounds of all frequencies and distinguish sounds by frequency (height).
