Utility method to convert an EAX decibel value to an amplitude factor.
EAX often expresses gain and attenuation in decibels scaled by 1000.
This method performs the reverse of that conversion to obtain a linear
amplitude value suitable for OpenAL.

@param eaxDb The EAX decibel value (scaled by 1000).
@return The corresponding amplitude factor.
