Psychoacoustics is the science of the relationship between physical quantities of sound and subjective hearing impressions. To examine these relationships, physical parameters, such as sound pressure level, frequency and modulation depth, are mapped to hearing-related parameters. Unlike the physical quantities, these hearing-related quantities – also referred to as psychoacoustic parameters – p...

Recent psychoacoustic studies of nonlinear distortion have yielded some new insights into what audible problems in loudspeaker might be related to. This paper will show the results of recent subjective tests which extend the work of various previous works to show that sound level significantly affects the perception of linear distortion in audio systems. This means that the hearing system itsel...

Seventeen patients with endophthalmitis due to coagulase-negative staphylococcus were treated over a nine-year period with vitrectomy, intraocular antibiotics, and systemic steroids and antibiotics. Fifteen patients presented with moderate to severe disease and visual acuities from counting fingers to light perception, while two had acuities of 20/60 and 20/200. A final visual outcome of 20/70 ...

A perceptual experiment concerning South Swedish word accents (accent I, accent II) is described. By means of editing and resynthesis techniques the F0 pattern of a test word in a phrase context has been systematically manipulated: initial rise (glide vs. jump) and final concatenation (6 timing degrees of the accentual fall). The results indicate that both a gliding rise and a late fall seem ne...

UNLABELLED Hearing aid. AIM To compare the performance, benefit and satisfaction of users of ITE, CIC and BTE digital hearing aid with noise reduction and omnidirectional and directional microphones. METHOD 34 users of hearing aid were evaluated by means of speech perception in noise tests and APHAB and IOI self assessment questionnaires. Prospective study. RESULTS Better results were obt...

price fairness and price satisfaction is one the most important fields in pricing and also in customer satisfaction. in this research, first the dimensions of price fairness, price satisfaction, customer satisfaction, and customer loyalty are extracted from marketing literature, then five hypotheses are developed. in proposed model, price fairness has direct impact on price satisfaction, custom...

ADAPT (Adaptive Dynamics and Active Perception for Thought) is a cognitive architecture specifically designed for robotics. The ADAPT architecture is in the initial state of development. ADAPT manipulates a hierarchy of perceptual and planning schemas that include explicit temporal information and that can be executed in parallel. Perception is active, which means that all perceptual processing...

Emotions are fundamental to human experience, influencing cognition, perception and everyday tasks such as learning, communication and even rational decision-making. Humancomputer interaction (HCI) systems capable of sensing user affective state and giving adequate affective feedback are, therefore, likely to be perceived as more natural, persuasive and trustworthy (Cassell & Bickmore, 2000). A...

Perception and manipulation of rigid objects has received a lot of attention, and several solutions have been proposed. In contrast, dealing with deformable objects is a relatively new and challenging task because they are more complex to model, their state is difficult to determine, and self-occlusions are common and hard to estimate. In this paper we present our progress/results in the percep...
