A Directional Audible Sound System using Ultrasonic Transducers
In general the audible sound has the characteristics of spreading, however the ultrasound is directional. This study used amplitude-modulating technique for an array of 8 ultrasonic transducers to produce directional audible sound beam. In this study sound field distribution for the directional audible sound beam has been investigated. The effect of different weightings varied with different fr...
متن کاملA Navigation System Using Ultrasonic Directional Speaker with Rotating Base
This paper proposes new method for object reference which enables a person to find surrounding objects and develops a navigation system named CoCo. CoCo employs an ultrasonic directional speaker with a rotating base. Ultrasonic wave transmitted by an ultrasonic directional speaker is converted to audible sound when it reflects on floor, wall, or object. Based on this property, CoCo can emit aud...
متن کاملFeature-based localization using fixed ultrasonic transducers
We describe an approach for mobile robot localization based on geometric features extracted from ultrasonic data. As is well known, a single sonar measurement using a standard POLAROIDTM sensor, though yielding relatively accurate information regarding the range of a reflective surface patch, provides scant information about the location in azimuth or elevation of that patch. This lack of suffi...
متن کامل3D Simulation of an Audible Ultrasonic Electrolarynx Using Difference Waves
A total laryngectomy removes the vocal folds which are fundamental in forming voiced sounds that make speech possible. Although implanted prosthetics are commonly used in developed countries, simple handheld vibrating electrolarynxes are still common worldwide. These devices are easy to use but suffer from many drawbacks including dedication of a hand, mechanical sounding voice, and sound leaka...
متن کاملUltrasonic Material Characterization System Employing an Array of Receiving Transducers
In a typical ultrasonic material characterization system, the output voltage of the transducer is recorded as a function of the relative position of the transducer and the specimen. The velocity and attenuation of the leaky surface acoustic waves and the reflectance function for the immersion liquid–specimen interface can be obtained from the recorded data. The experimental arrangements with lo...
