Savart is a way to tell how fast something is vibrating, like a musical instrument or your voice. Imagine you have a toy car with a wheel. When you move the car, the wheel spins round and round. The number of times the wheel spins in one second is called its frequency.
Now, imagine the wheel has little bumps on it. Each time a bump goes around, it makes a sound. But if the bumps are really close together, the sound will be higher pitched. If the bumps are far apart, the sound will be lower-pitched.
Savart is a way to measure how far apart the bumps are. To find Savart, you put a sound detector (like a microphone) next to the vibrating object, and the detector measures how many sound waves it hears in one second.
If an object's frequency is really low (meaning it vibrates slowly), it will produce a deep sound, like a bass guitar. If the frequency is really high (meaning it vibrates faster), it will produce a high-pitched sound, like a whistle.
So, to summarize, Savart is a way to measure how fast an object is vibrating by counting how many sound waves it produces in one second. This helps us understand the pitch (or highness/ lowness) of the sound the object produces.
