Evaluation of Sound Localization under Conditions of Covered Ears
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 ...
متن کاملSound effects: Multimodal input helps infants find displaced objects.
Before 9 months, infants use sound to retrieve a stationary object hidden by darkness but not one hidden by occlusion, suggesting auditory input is more salient in the absence of visual input. This article addresses how audiovisual input affects 10-month-olds' search for displaced objects. In AB tasks, infants who previously retrieved an object at A subsequently fail to find it after it is disp...
متن کاملIs Attention Shared Between the Ears?
This study tests the locus of attention during selective listening for speech-like stimuli. Can processing be differentially allocated to the two ears? Two conditions were used. The simultaneous condition involved one of four randomly chosen stop-consonants being presented to one of the ears chosen at random. The sequential condition involved two intervals; in the first S listened to the right ...
متن کاملComparison between intensity and pressure as measures of sound level in the ear canal.
In-the-ear calibration of sound pressure level may be problematic at frequencies above 2 kHz, because the pressure can vary significantly along the length of the ear canal, due to reflection of sound waves at the eardrum. This issue has been investigated by measuring behavioral thresholds to tones in a group of human subjects (N = 61) for two different insertion depths of an insert earphone. Th...
متن کاملGender - bending alligators use
It’s a boy! Or is it? We live in an era of blurred gender lines, but for many reptiles this has always been a hot topic. In crocodilian as well as several turtle species, cranking up the thermostat a few degrees during a critical developmental window, called the thermo-sensitive period, will turn a whole clutch of eggs into males. Hormones also contribute to sex determination in these species, ...
