Quote: "3.4.1.11 NOISEHEARD
Description: Is true if the entity can hear a noise. If true the sound is set as a possible target for the entity.
The engine determines this by comparing the strength of the sound to the distance between the entity and the sound using the following test: 10 x SoundStrength > Distance.
Example 1: SoundStrength = 6, Distance = 55
10 x SoundStrength = 60 (> Distance = Yes, sound heard)
Example 2: SoundStrength = 6, Distance = 100
10 x SoundStrength = 60 (> Distance = No, sound not heard)
Any sound heard within 50 units is ignored.
Example: :noiseheard:state=1"
