Quick answer, no. Your index finger is only travelling about 20 miles per hour when it hits the base of your thumb, while the speed of sound is 767 mph. So, what you hear is essentially just a skin on skin slap.
But, if you want to break the sound barrier in your home, just snap a towel. Like a whip, the end of the towel flips around to change direction from forward to backward faster than the sound barrier.
Now isn’t that amazing! You can’t drive your car faster than perhaps 1/7 the speed of sound, Your model rocket kit will only hit 1/3 to 1/2 as fast as sound. Even your jetliner flight across country tops out at 6/7 of the sound barrier. And yet, just grab a towel and snap it and you’ve created a sonic boom in your bathroom (the best echo is in there).
