That's a somewhat crude way of putting it; when studying a resonator it's better to look at the q factor: https://en.wikipedia.org/wiki/Q_factor
Lower q factor means a higher spread of frequencies can trigger them. Mammalian hair cells have q factors of 5-10. Q=10 is pretty high for a biological resonator, but pretty low compared to, say, even crude electronic equipment. A typical LC oscillator has Q of 100 or more.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
