Multi-mode, multi-channel psychoacoustic processing for emergency communications
First Claim
1. A method for enhancing a user'"'"'s ability to discern the source and/or priority of communications, the method comprising the steps of:
- scanning input communication signals for an active signal;
determining if other characteristics are available on the received signal to further define the signal;
programming a communication device with a profile;
utilizing the profile to prioritize the communication signals; and
associating a given input communication signal with an acoustical spatial location or loud speaker.

Abstract
An emergency radio communication system utilizes radios with headset, headphones, earphones and/or custom audio interfaces for a minimum of two audio channels. Each radio receives multiple channel/frequency communications and spatially locates the received communications at predetermined “ear” locations comprising left earphone, right earphone, and both earphones (right and left) according to the source of the received communications. In one specific example, a first fire department communications may be fed into the left earphone at a 100% level and a second fire department communications or air support communications may be fed into the right earphone at a 100% level. Control and command communications may be fed into both the left and right earphones at equal levels. Thus, in this example, the user spatially hears communications from the first fire department to the left, communications from the second fire department to the right, and communications from air support from the center.

12. A method of selecting the acoustic spatial location of a transmitted signal, the method comprising the steps of:
-
sampling the input audio signal upon detection on an interrupt;
amplifying the signal and converting the signal to digital for DSP processing;
processing the signal by a speech compression routine to raise the average signal strength;
comparing the signal to a VOX set point and if the signal exceeds a level set by a control processor switching a communication device to transmit mode, the VOX is enabled;
switching a communications device to transmit mode using at least one button if the VOX is disabled; and
determining the output acoustic spatial location of a receiver of the signal utilizing a table located in the communication device. - View Dependent Claims (13, 14, 15)
