In any light ac if you covered up all of the insts I bet you could make a decent fist of a landing based on the noise the engine is making and the attitude of the ac outside the window.
I doubt you could sense the wind noise different of say 10kts and on approach you may well have the engine on idle or low power so I doubt those cues will work well. However, the level of mushyness in the handling should be an excellent indicator. You know how utterly unresponsive the a/c just prior to the stall and how realtively unresponsive it is on approach. The difference in 15kts is quite marked (on the little un's I've flown anyway).
