When we talk about ultrasound, it is actually a kind of sound energy that a normal human ear cannot hear. The frequency of ultrasound waves is 20000 hertz. Animals have the natural ability to use it when emitted as a wave in communal and navigational perspective. However, humans use ultrasound as well but not without technical assistance and it is used in many industrial and medical purposes.
Uses of Ultrasound In Daily Life
1. Field of Communication
Few animals such as bats and frogs have the ability to use ultrasound to communicate with each other. Bats emit high pitched sound of short wavelength in order to navigate. These waves hit the surrounding and bounce back allowing bats to get an exact map of the surrounding. These bats communicate with each other with ease, thanks to the ultrasound waves.
2. Ultrasonic Cleaning
One of the many applications of ultrasonic sound waves is ultrasonic cleaning. It is used to get rid of impurity from certain devices that are absorbed in aqueous solution. Materials like glass, metals, and ceramics can be cleaned using this and in addition to that, ultrasonic waves can be used to remove grease, oil and dirt. Ultrasonic sound waves are also used in industries in order to get rid of chips and oil from machinery and other industrial equipments. It is also used to get rid of sludge and lubricant from the apparatus of aircraft and automobiles.
3. Ultrasonic Welding
Ultrasonic sound waves are also used for the purpose of welding plastic. High frequency ultrasonic vibrations are used to weld couple of parts of the plastic. However, this welding process is very well programmed and has time and frequency already programmed into the welding machine and computer carry out each and every step of the welding process. (Our welding products include: Ultrasonic Welding Generator & Ultrasonic Welding Transducer )
The welding process is a little complicated to understand. Its mechanism base on the method in which semi piece of plastic is positioned on a permanent anvil and the other part is placed on top of it. After that, a horn is placed down on an extension that is coupled to the transducer of the welding machine. This horn is then used to apply swift but low-amplitude ultrasonic vibrations in order to weld plastic. The ultrasonic sound waves are then converted into heat because of the rapid vibrations, which result in welding the two parts of the plastic together. However, it is still very risky to use this method to weld very large apparatus because a massive amount of energy is released during the welding process.
4. Other Uses
In addition to the above mentioned uses of ultrasonic waves, there are several other used of it as well. For example, ultrasonic motion detectors use same ultrasonic waves in measuring distance. These motion detectors get the job done by emitting ultrasonic pulses and then measure the time upon the return of those waves. Sonogrpahy is a process that is used to create the images of the internal organs of the body. This process also uses ultrasound waves to get the job done.
