The sound,or sound waves, with frequency higher then human hearing span are called ultrasound. The healthy human ear can usualy hear up to 20kHz.
Ultrasound is produced and detected using an ultrasound transducer. Ultrasound transducers are capable of sending an ultrasound and then the same transducer can detect the sound and convert it to an electrical signal to be diagnosed.
To produce an ultrasound, a piezoelectric crystal has an alternating current applied across it. The piezoelectric crystal grows and shrinks depending on the voltage run through it. Running an alternating current through it causes it to vibrate at a high speed and to produce an ultrasound. This conversion of electrical energy to mechanical energy is known as the piezoelectric effect. The sound then bounces back off the object under investigation. The sound hits the piezoelectric crystal and then has the reverse effect - causing the mechanical energy produced from the sound vibrating the crystal to be converted into electrical energy. By measuring the time between when the sound was sent and received, the amplitude of the sound and the pitch of the sound, a computer can produce images, calculate depths and calculate speeds.
industrial applications ultrasonic cleaning,ultrasonic cutting,ultrasonic machining,metal forming,metal welding, medical applications
Chemists use ultrasonic technology to assist in various processes such as mixing, dispersing, emulsifying, and degassing. Ultrasonic waves create cavitation, which generates high shear forces and intense local heating, allowing chemists to accelerate reactions, enhance mass transfer, and improve product quality by creating fine particles or emulsions. Ultrasonic technology is also used for cleaning equipment and surfaces in laboratories.
industrial applications of ultrasonic waves: 1. ultrasonic welding 2. ultrasonic cleaning. 3. ultrasonic drilling. 4. ultrasonic soldering. +++ 5. Flaw detection in metals etc. And many others if you stretch the term "industrial to include, say, medical!
ultrasonic wave is sound frequency
Ultrasonic sounds are sounds that are above our hearing range.
bats can hear ultrasonic sound
whale can hear ultrasonic sound waves.
When an object starts to move at ultrasonic speeds it will create a sonic boom.
That is the definition of ultrasonic!
A common method of attachment utilizes an ultrasonic transducer.
Ultrasonic - 2012 is rated/received certificates of: USA:R
All you need is an "ultrasonic" signal to come into it.
