Abstract

It can be advantageous for mobile applications of audio systems to be lightweight and small. An experiment investigated speech intelligibility for multiple talkers of a stereo presentation and two different 3D audio systems. The 3D audio systems consisted of a relatively small and lightweight Commercial-Off-The-Shelf (COTS) display and a professional hardware display considered bulky and heavy. Each of 12 participants listened to one to four call signs combined with two background voices, with the task to identify and localize the voice of each call sign. The results show that the COTS 3D audio as compared to stereo generated a larger amount of complete sets of identified call signs and a larger proportion of identified single call signs in a set. The professional display generated a larger proportion of identified single call signs in a set compared to stereo. These results suggest that 3D audio based on COTS components could be used for increasing intelligibility of radio calls in mobile applications demanding relatively small and lightweight equipment.
