HERE are many translated example sentences containing "ULTRASONIC SOUND" - english-spanish translations and search engine for english translations. The frequency of the sound is somewhere in the range of ultrasound, this ensures more concentrated direction of the sound wave because sound at higher frequency dissipates less in the environment. The key difference between infrasonic and ultrasonic waves is that infrasonic waves include sounds emitted at levels below frequencies of noise that can be heard by humans while ultrasonic waves are those that exceed 20 kilohertz, which is … The ultrasonic sensor sends 8 pulses of 40KHz via the trig terminals (inaudible to humans, it's ultrasounds). Animals such as bats and porpoises use ultrasound for locating prey and obstacles. 7. Sentence examples for an ultrasonic sound from inspiring English sources. Ultrasonic definition is - having a frequency above the human ear's audibility limit of about 20,000 hertz —used of waves and vibrations. How to use ultrasonic in a sentence. The device produces an enormously loud, pulsating and aggressive ultrasonic sound of about 21 kHz which is not audible to most people, but represents a considerable annoyance for wild animals which, therefore, try to avoid it. If an application requires a target angle beyond the capabilities of a single sensor, two sensors can be teamed up to provide an even broader angle of tilt. Some ultrasound-emitting devices are used to silence barking dogs without hurting human hearing, because only dogs find the sounds intolerable. Examples for business, study, careers, love, and more... https://www.ece.wpi.edu/research/Ultrasound/, https://hyperphysics.phy-astr.gsu.edu/Hbase/sound/usound.html, https://www.radiology.ucsf.edu/ultrasound/. 4. exact 56. similar 3. related RELATED an acoustic sound. Since the early 1960s, researchers have been experimenting with creating directive low-frequency sound from nonlinear interaction of an aimed beam of ultrasound waves produced by a parametric array using heterodyning.Ultrasound has much shorter wavelengths than audible sound, so that it propagates in a much narrower beam than any normal loudspeaker system using audio … Sound wave is a vibration that is transmitted through a medium, such as air, water, and metals. These waves possess a number of properties of sound waves and exhibit some new phenomena also. Oil Bird. Ultrasound is considered a safe alternative to X rays, and other forms of radiation based scans. The working principle is really simple. They cannot be heard by human beings. Contrast with, (acoustics) Beyond (higher in frequency than) the range of sound perceptible to the human ear; with a frequency of 20. Steatornis caripensis, the oil bird of South America, forages during the night and sleeps in caves during the day. 1. 6 Basic Principles of Sound (cont.) Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing.Ultrasound is not different from "normal" (audible) sound in its physical properties, except that humans cannot hear it. Ultrasonic waves are special sound waves whose frequency range is beyond the range detectable by the human ear. Of, relating to, or involving ultrasound. The definition of ultrasonic, also known as ultrasound, is sound waves that have a higher frequency than the human ear can hear. These sound waves are used as 'sound radar', recording and interpreting reflected sound to analyze tissues in medical sonography, and to conduct non-invasive scans of the body. Ultrasonic jewelry cleaners use sound waves that vibrate through the water to remove particles and dirt from jewelry pieces. Multi-path ultrasonic flow meter with conventional pressure and temperature transmitters (typically used in concert with a flow computer) BTU gas chromatograph to poll and report the Ultrasonic metered rates and diagnostic points Resident program in the GC to calculate the speed of sound … They are also used to administer therapy to various parts of the body. Ultrasou­nd has been used in a variety of clinical settings, including obstetrics and gynecology, cardiology and cancer detection. Ultrasound imaging or sonography is often used in medicine. All Rights Reserved. This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy young adults. An example of ultrasonic is an ultrasound image of an unborn baby. Ultrasonic waves are very similar to light waves in that they can be reflected, refracted, and focused. They are used by some animals and in medical or industrial technological devices. High frequency ultrasonic vibrations are used to weld couple of parts of the plastic. Ultrasonic waves are sound waves transmitted above the human-detectable frequency range, usually above 20,000 Hz. Capacitive transducers use electrostatic fields between a … Our ultrasonic sensors, made with piezoelectric crystals, use high frequency sound waves to resonate a desired frequency and convert electric energy into acoustic energy, and vice versa. High frequency sound waves (frequency > 20000 HZ) also known as ultrasonic waves are introduced in a test object through a probe, these waves travel through the material on a predictable path. The results of the scans are translated into images for analysis. Here are five examples. Since ultrasonic sound waves reflect off the target object, target angles indicate acceptable amounts of tilt for a given sensor. Take your productions to the next level with our high-quality Sample Packs and Project Files. Ultrasonic sound is too high for people to…. 13. Frequencies above 18 Kilohertz are usually considered to be ultrasonic. Learn more. They are as follows: (1) Audible waves are waves that lie within the range of sensitivity of the human ear. | Meaning, pronunciation, translations and examples Infrasound can be generated by both natural and man-made events. 7. ultrasonic meaning: 1. Ultrasonic sentence examples. Ultrasonic sentence examples. Ultrasonic Humidifier - This model is well-suited for medium to large size rooms and can run for 27 hours without needing to be filled. The main advantage of ultrasound is that certain structures can be observed without using radiation.Ultrasound can also be done much faster than X-rays or other radiographic techniques. The ultrasonic signals utilized by these bats fall into three main categories. Ultrasonic-Sounds.com Frequencies above 20,000 Hz are in the ultrasonic range. Ultrasonic and supersonic - definition Ultrasonic is used for ultrasound waves and is defined as waves with frequency more than 20 kHz. They then wait for the sound to be reflected back, calculating distance based on the time required. an acoustical sound. Infrasonics, vibrational or stress waves in elastic media, having a frequency below those of sound waves that can be detected by the human ear—i.e., below 20 hertz. Sound waves can be used to determine distances and structure of some objects or tissues. Ultrasonic Humidifier - This model is well-suited for medium to large size rooms and can run for 27 hours without needing to be filled. It's an ultrasonic toothbrush with whitening capabilities built directly into the brush head, eliminating the need for a separate step for whitening. * The echo terminals receives the ultrasound pulses and the sensor calculates the … Sound is better for this application than light because sound is not affected by reflectivity, translucence, or color. It explains what ultrasonic devices are and gives examples of its uses. To fly about without injury in the shadowy world in which it lives, the oil bird employs echolocation. There are two suborders, Megachiroptera and Microchiroptera.
