Are you on a indoor trainer? Turn up the radio or television.
Riding outside? Get over 16 mph so the wind noise in your ears drowns it out. Though it's unlikely at any speed they your friends riding next to it are bothered by it or even can hear it.
If it is truly noisier than others, then make sure it's adjusted properly and keep the chain lubed.
It is possible that getting a crank or rings and cogs made of different materials from a lower tier level product might help.
