I was walking on the very edge of the wood at a farm from an NPC village and created no noise.

I was on a seed I was playing with at my friends house on the Xbox 360 Edition of Minecraft and created a world with the seed "tantom". It looked very similar from the PC to the Xbox. I was just walking around this farm I ran into and walked on the last pixel of the wood blocks and heard no walking noise. Therefore, making it a strange glitch I found and making myself post this.
