Evaluation of Sound Localization under Conditions of Covered Ears
نویسندگان
چکیده
In this paper, we examine how covering one or both external ears affects sound localization on the horizontal plane. In our experiments, we cover subjects’ pinnae and external auditory canals with headphones, earphones and earplugs, and conduct a sound localization test. The results indicate that front-back confusion rates increase when covering both external ears with open-air headphones, and one ear with an inner earphone and an earplug. Furthermore, the incorrect answer rate is high when sound sources and an occluded ear are on the same side when putting on an inner earphone and an earplug. We consider that factors causing front-back confusion could be clarified by comparing these results with characteristics of HRTFs.

A Microphone-Array-Based System for Restoring Sound Localization with Occluded Ears
Current helmets and hearing protectors interfere with the sound transmission to the ears and therefore affect the perception and localization of speech and other useful sounds. This is can be a serious drawback especially when the person wearing the protection has to operate in complex, unpredictable environments. A novel electro-acoustic system for sound pass-through was developed that can mak...
متن کاملSelective deficits in human audition: evidence from lesion studies
The human auditory cortex is the gateway to the most powerful and complex communication systems and yet relatively little is known about its functional organization as compared to the visual system. Several lines of evidence, predominantly from recent studies, indicate that sound recognition and sound localization are processed in two at least partially independent networks. Evidence from human...

متن کاملObject localization using a biosonar beam: how opening your mouth improves localization
Determining the location of a sound source is crucial for survival. Both predators and prey usually produce sound while moving, revealing valuable information about their presence and location. Animals have thus evolved morphological and neural adaptations allowing precise sound localization. Mammals rely on the temporal and amplitude differences between the sound signals arriving at their two ...

The paper presents rst results on audio-quality evaluation following the auditory-perception modeling paradigm of TWO!EARS, a FET-Open project funded under FP7 ICT by the European Commission (www.twoears.eu). The project targets an interactive system for binaural auditory perception, including input from the visual modality. In its ultimate form, it will be based on an interactive robot platfor...
