INTRODUCTION Defects of Hearing •Hearing defects means ear is not working correctly or as well as it should. •It may occur in more than one part of the ear. •1. DEAF-full or partial decrease in the ability to detect or understand sounds. Deaf usually caused by : - Eardrum is torn-cannot function - Ossicle bone fused together-can’t vibrate - Auditory nerve damaged by loud sound - Cochlea damage due to sickness/ drugs •2. Temporary hearing loss-build-up of earwax •3. Presbycusis- hearing loss

There are many uses for sound in the world today. Performers can take advantage from a better understanding of sound‚ architects needs to understand sound to design effective auditoriums‚ and many new types of technology apply sound recognition. Another use of sound is in the area of science called Nondestructive testing‚ or NDT. Ultrasonic testing (UT) has been practiced for many decades. Initial rapid developments in instrumentation encouraged by the technological advances from the 1950’s continue

What are Ultrasound Scanners? Ultrasound has been utilized as a tool in beef and diary research systems for many years‚ and in more recent yeas has become available to commercial livestock agriculture. An ultrasound is an electronic instrument that sends out ultrasonic waves from an attached device called a transducer. Waves pass freely through fluid and are reflected back to the probe resulting in an image that can be identified as the placenta‚ fetus‚ or other organs. Ultrasound may also be used

SYNOPSIS Subject :- ULTRASONIC RADAR Group Members :- INTRODUCTION Radar is a system that uses electromagnetic waves to identify the range‚ altitude‚ direction‚ or speed of both moving and fixed objects such as aircraft‚ ships‚ motor vehicles‚ weather formations and terrain. The term RADAR was coined in 1941 as an acronym for Radio Detection and Ranging. The term has since entered the English language as a standard word‚ radar‚ losing the capitalization in the process. Radar was originally

The sizes of these transducers are the main drawback since they are from 30 up to 45 mm in diameter. A further analysis of this structure and its dynamic features is found in [Attila et. al.‚ 1995]. The piezoelectric transducer is based on a piezoelectric crystal that either is forced into mechanic oscillation by

using 8051 A simple ultrasonic range finder using 8051 microcontroller is presented in this project. This ultrasonic rangefinder can measure distances up to 2.5 meters at an accuracy of 1 centi meter. AT89s51 microcontroller and the ultrasonic transducer module HC-SR04 forms the basis of this circuit. The ultrasonic module sends a signal to the object‚ then picks up its echo and outputs a wave form whose time period is proportional to the distance. The microcontroller accepts this signal‚ performs
