What is an ultrasonic circuit?

Sounds are heard everywhere in nature, with the exception of the vacuum of the universe. People and animals often rely on sound for communication, navigation and location information. When people need to interpret sounds above the hearing range, the ultrasonic circuit can create, send and receive high -frequency signals.

ultrasounds are sound waves with frequencies higher than the human ear. Typical ultrasonic frequencies are greater than 20,000 Hertz (20 kHz) or cycles per second. High frequency sounds have a wide range of uses, including distance measurement, medical use and safety equipment.

Sound waves can be used to measure distances. The ultrasonic circuit can create a high -frequency sound pulse of a short duration that will travel through the air or water and measure the amount of time to return the pulse to the device. The software then calculates the distance to the object. The sound speed is different depending on whether air or water is present, so May software right for water, temperature and density type.

Sonar or sound navigation and range is used in ships and submarines for navigation and detection. It is an ultrasonic circuit using converters to send and receive sound pulses to detect other blood vessels or underwater elements. Short pulses are used rather than continuous frequencies to provide more sound energy for accuracy.

Another use of sonar ultrasound is to control underwater structures, geology and search and rescue. Portable sonar devices can be connected or pulled behind surface ships. These devices send ultrasonic pulses in the required directions and create images of underwater structures based on discouraged sounds. Fish search engines used on private and commercial fishing vessels use a similar system to detect fishing schools under the boat.

Ultrasonic circuit can be used as a medical imaging device and usuallyis referred to as an ultrasonic machine. The perimeter creates a focused ultrasonic frequency in a hand -held probe that can be placed on the patient's body. The software processes reflected sounds and creates an image of internal organs on the monitor. The resulting images can be used for medical diagnosis, observation of heart and blood vessels, and prenatal observation of the fetus or unborn baby inside the mother.

ultrasonic frequencies can travel via solid materials and can be used as a diagnostic tool. A portable device similar to an ultrasonic machine can be used on bridges, pressure vessels or other equipment to find internal deficiencies or cracks before failure. This technology is used for non -destructive testing of structural parts of aircraft during routine inspections. It can find very small cracks and tired areas of repeated take -offs, landing and tension in flight.

Sound can be used to provide signals used for safety systems. The principle is the same as Sonar or ultrasound,with a frequency sent and received by ultrasonic circuit. In this case, any accepted signal indicating the movement may trigger the alarm perimeter. These systems can be used where infrared or thermal sensing systems do not work properly due to temperature or other conditions.
