![]() ![]() As the frequency or pitch of the sound increases it. Using terms such as more vibrations or it vibrates more is likely to lead to confusion among your children. A sound having a higher frequency is said to have a high pitch and lower frequency sounds have low pitch. With my headphones on, when I gradually increase the volume, the high pitch sound doesnt change much, but the low pitch sound was easier to. There are two separate ways of describing sounds here, and the aim must be to help children differentiate between them. The central learning challenge for children is for them to develop a clear understanding of the difference between describing sounds in terms of loudness (amplitude) and pitch (frequency). ![]() ![]() Right Lines: If the amplitude of the vibration of the source is bigger, the sound produced will be louder. Wrong Track: With bigger vibrations it will be a higher sound. Right Lines: There are more vibrations each second, so the frequency will be higher, giving a higher pitched sound. ![]() Wrong Track: There are more vibrations, so it will be louder.
