detonation is the premature cumbustion of the air fuel charge. the air fuel charge in the combustion chamber ignites before the spark plug fires. this can cause apex seal failure, damage to rotor housings, damaged end plates, rotor damage. on the turbo motors it can be caused high air intake temps, boost creep, carbon build up, and advanced timing under boost. most of the time it cannot be heard by the driver and if it can be it will sound kind of like a rattling noise.

No, That is actually Pre Ignition.\

Detonation is when combustion occurs at the right time but instead of being a controlled burn, it pretty much explodes in an uncontrolled manor, the only thing controlled about it is when the spark sets it off.

See above link for more information. I could tell you more specific rotary engine information but I'm out of time, shift is almost over.
