ENVIRONMENTALLY CONTROLLED FREQUENCY RESPONSE MODIFICATION FOR LONG RANGE HAILING SYSTEM

摘要

A systems and methods for altering audio for more effective delivery to long range targets An example of the present invention includes a speaker (12) coupled to a processor and one or more sensors suitable for sensing environmental conditions such as temperature and humidity (24-28) The processor reads the output of the sensors and compensates for frequency dependent attenuation likely to occur at the sensed environmental condition (20) In one embodiment, the user specifies a range that the sound is to travel and an equalization table compensating for attenuation at the desired range is selected according to the user input.
