Lonely Sounds: Sonic Self Sufficiency, Personal Control, and Social Shields
In the winter of 1979 Sony introduced a hand-held cassette player called the Walkman—a device that catered to a mass culture that had come to demand personal control over the musical experience. The Walkman’s mobility allowed for unprecedented individual control over the environment: a barrier that kept unwanted sounds or unwanted others out. In the post World War II era, loneliness and recorde...
متن کاملMinimally invasive dentistry using sonic and ultra-sonic devices in ultraconservative Class 2 restorations.
AIM Within the context of minimally invasive dentistry this article describes the sonic and ultrasonic cavity preparation techniques and assesses their advantages and disadvantages, clinical difficulties of their use, and offers a statement about these devices. BACKGROUND Ultra-conservative Class 2 restorative techniques require the use of devices such as sonic and the new ultrasonic preparat...
متن کاملUltra Sonic Image Interpretation for Non-Destructive Testing
For interpretation of ultra sonic images an image interpretation system based on case based reasoning is proposed. We describe the case representation and the case based reasoning process.
متن کاملUltra Sonic Sprayer Controlling Dust in Experimental Poultry Houses
Dust control tests of experimental enclosed layer and floor feeding broiler houses were performed with ultra sonic sprayer units which have some advantages such as 1) low cost, 2) low electric power consumption, 3) forcing the charge and 4) unnecessary to lay pipes to spray. With spraying 2 % solution of emulsified canola oil in layer house, the concentration of dust with aerodynamic diameter (...
متن کاملSonic Handprints: Person Identification with Hand Clapping Sounds by a Model-Based Method
Sound-based person identification has largely focused on speaker recognition. However, also non-speech sounds may convey personal information, as suggested by our previous studies on hand clap recognition. We propose the use of a probabilistic model-based technique for person identification based on their hand clapping sounds. The method is based on a Hidden Markov Model which uses spectral tem...
