A Device and Method for Improving Communication Through Dichotic Input of a Speech Signal
Abstract: The device and method of the present invention improves electronic communications which have behavioral consequences, including for example, flight communication, two-way closed circuit communication such as for fire, police, miners, scuba divers and other health and safety workers, network and media communications, and even for mobile communication which happens during activities such as cellular or mobile conversations during driving. Dichotic listening techniques are altered to enhance dyadic (involving two people) interactions with a partner.
The speech of at least the first member of the dyad is filtered to isolate the component below 0.5 Khz, which will be input with a gain to the left ear of the second person (provided that they are right-handed), and thus their right cerebral hemispheres, and the component with a frequency above .5 Khz. will be input to their right ears, and thus their left cerebral hemispheres. The apparatus of the invention includes a communication source, which could include live and simultaneous broadcast, or pre-recorded communication. This constitutes the communication input which is directed to a filter to split off the speech fundamental frequency, i.e. the SFF. The post filtered communication signal, or "SFF augmented signal" is fed to a differentiation device which differentiates two signals, one with an enhanced SFF, and one without the enhancement subsequently, a delivery device delivers the now differentiated left and right signals to the appropriate ears.
Applications: Military, pilot helmets, earphones, all 2-way closed circuit communication for emergency forces and health/safety workers, construction communications, training, simulators, cell/mobile phones while driving, etc. and gaming
