A parabolic dish microphone is like a mirror telescope for sound. A parabolic reflector is used to collect and focus sound waves to a microphone receiver [1, 2]. The parabolic shape has the property that all sound waves impinging parallel to the central axis of the dish are reflected to its focus point. When the dish is aimed at a distant sound source it is safe to assume that all the sound wav...

a familiar criticism of kant, made by hegel and his followers, j .s. mill and others, is that there are no maxims that are in fact contradictory, as required for morality on kant's view. in this paper, i discuss the suggestion that our capacity for rational reflection itself implies universality, and that it is this universality that obliges us to act morally. i consider the idea that self...

“Acousmatic Foley” is practice-based research on sound dramaturgy stemming from musique concrète and Foley Art. This article sets out a theory based the concept of “son-en-scène”, which forms sonic content mise-en-scène, as perceived (esthesic sound). The departs well-known features soundscape (R. M. Schafer, 1999) listening modes in film asserted by Chion (1994), order to arrive at three main ...

Background. A field study conducted by researchers found the balls used by visual impairment students at school basically used the sound by a small bell inside the ball. However, the sound emitted from the ball is very limited, the ball will sound when it is moved. This makes it difficult for students with visual impairments to find a missing ball that not emitted makes a sound. Objectives. A ...

chainsaw is an important machine for tree felling limbing and bucking in hyrcanian forest and the major problems related to using forest machines was sound intensity. the aim of this study was to measure the sound level in occupational exposure of workers, determine the exposure time of workers and comparison of the variables among the workers. this study was carried out in namkhaneh district i...

Large-volume cubic high-pressure apparatus is commonly used to produce synthetic diamond. Due to the high pressure, high temperature and alternative stresses in practical production, cracks often occur in the carbide anvil, thereby resulting in significant economic losses or even casualties. Conventional methods are unsuitable for crack detection of the carbide anvil. This paper is concerned wi...
