In order to drive insects, rodents and other pests away, people can try ultrasonic pest control devices since they produce a high-pitched sound. However, some people think these devices will affect other pets. Range As we know, the sounds from ultrasonic pest control devices lose about half their energy within 15 feet and are ineffective

As we all know, a lot of animals can produce ultrasonic sound which is greater than 20 kilohertz for several purposes. However, do you know which birds & animals are capable of producing ultrasonic frequencies? Oil Bird Steatornis caripensis, the oil bird of South America, sleep in caves during the day and forages during the

A sonicator can be utilized to break up, disperse and sheer target material samples through its focused ultrasonic frequencies. It plays a great role in chemical, biological, industrial and environmental fields. Focused sound waves are produced by the sonicator unit, these waves reverberate in the chamber and increase the vibration strength of target materials, breaking

Ultrasonic Horn for Cylindrical Grinding Machine https://www.bjultrasonic.com/shop/ultrasonic-horn/ Ultrasonic machining, also known as ultrasonic impact grinding, is a machining operation in which a vibrating tool oscillating at ultrasonic frequencies is used to remove material from the workpiece, aided by an abrasive slurry that flows freely between the workpiece and the tool. It differs from most other

Usually the frequency limits of applications are ascertained through the resonances involved with the transducer design and its size and shape. For a piezoceramic sheet, there is no limit for inherent frequency. A sheet of PSI-5A material which is 2.85″ square, .0075″ thick has planar dilatation mode of about 14 KHz and of 13 MHz

So far there are no known negative effects of ultrasonic frequencies on human body. These frequencies, as a matter of fact, are used to detect and treat many human diseases.

The frequencies of the ultrasonic sound waves used by ultrasonic cleaners to clean objects are very high, above 20 kHz. That is beyond the level of frequency that human ears can detect. Therefore, even though ultrasonic frequencies are very high, they cannot damage our ears. What you should be concerned about are the undertone frequencies.
