Answer:
no.
that is not true because, you have to think "well what can I clap on one hand for it to make a sound?" or "is my clapping metaphorical as in silent applause?"
there are many answers to this but there wouldn't be a definite "yes" or "no"
Well.... No. Clapping is useing both hands and hitting them against eachother to make a sound, you cannot make a sound useing only one hand. Unless you use a object or another hand. There for there is no sound of one hand clapping.
