Abstract:

This study was designed to gain some preliminary information about the effect on performance of excising portions of the speech spectrum. It is recognized that sophisticated techniques, such as digital transmission of voice, are being developed and employed to overcome the effects of noise and to transmit communications in a secure form. There are, however, instances where these techniques are not feasible and it may be useful to reduce the amount of spectrum dealt with by excising selected bands.
