48. Loud Noises Startle And Get Attention

From a design aspect, using noises to indicate something is a good way to get attention. Use these noises sparingly and not in a too often repetitive manner. The more often someone hears a noise, the more likely they are to ignore it when it happens all the time. Pick noises that are appropriate too. A soft sound is not as attention getting as a louder one, but both still have their places.
