Sensitivity index

The sensitivity index is like a measure that tells us how good our ears are at hearing sounds. It's like a way to measure how much we can hear and how well we can tell the difference between different sounds.

Imagine we are playing a game where someone is making sounds with different objects, like a bell or a whistle, and we have to guess which object they are using just by listening to the sound. The sensitivity index tells us how good we are at playing this game, and how likely we are to guess the right answer.

The sensitivity index is important because it helps us understand how well our ears are working. If we have a high sensitivity index, it means we have good hearing and are able to hear even subtle differences in sounds. But if we have a low sensitivity index, it could mean that we have some hearing loss or difficulty hearing certain frequencies of sound.

So, the sensitivity index is like a score that tells us how good we are at hearing sounds, and it helps us understand our hearing abilities.
