The loudness of an alarm is determined by size, frequency and distance. A cheap alarm is small, produces a very high frequency and has its loudness measured very close to it. It won't scare away anything.

The beeper in my smoke detector is 1.625" in diameter and is loud but it produces a very high frequency. It won't scare away an intruder.
