well i guess that every kiai is unique. you might be using the same method but the result is always different for every kendoka which means that every kiai,whether loud or not so loud, may have a similar but not the same resonance it might produce.well as long as every kiai posseses the spirit it requires, the bearing will always be there.anyway most kendoka out of shyness or being naive initially produces a soft kiai.for every experience he gains his spirit increases and same goes for his kiai.if you practice more often you will notice that your kiai in some point of time is starting to sting your opponent unwittingly as you finally develop a stable and strong kiai that can strike fear into the hearts of your opponent.
