Here, I want the word pertaining to the sound of human footsteps while walking down the stairs. The word I am looking for, can be contrasted with the word of the sound of footsteps of army marching. I am just looking for that word that denotes the sound of footsteps (hitting on the stairs) while walking down the stairs.
My research suggests two best options; one is adjective to describe that sort of sound, and the other, noun:
1. Click-clacking sound.
I am not fully satisfied with the word clomp as it denotes the sound of a heavy tread.
I heard the ______ of her footsteps when she was walking down the stairs.
