Ultra sonic wave is high frequency sound waves than the human ear to hear. Generally, the average human ear will hear up to 15 KHz, only just, but they may be old to hear high frequency sounds than this. Usually the words ultra sonic sound waves thus often means that there is a higher frequency of 20 KHz and up to higher until limited did not specify by how much.The cause that has brought the wave ultra sonic neighborhood used it, because that is the direction the waves are made, we can aim the sound waves to the target by a specific. This is one of the properties of waves. The more the higher frequency waves have wavelengths becomes shorter. If the longer wavelengths (the opening sound. Audio frequency generator), such as the 300 Hz frequency in the air will reach about 1 m in length, a little bit, which is longer than the space that allows the sound waves coming out of the sound wave is typically many broken Ben the outside edge of the sound generator causing the dispersion direction, but if the high-frequency wave is located in the ultra sonic, like 40 KHz in air wave length is only about 8 mm. smaller aperture where only the sound of the frequency range to the sound wave diffraction is not at the edges, so a narrow beam or ejaculation is called with the direction.To have the direction of the sound wave ultra sonic district allows us to use it. By using frequency-dependent applications such as sound waves traveling through the air, and then. The frequency with which it is often limited to no more than 50 KHz frequency was higher than that because of this, the air absorbs sound waves. The level of intensity of sound waves at a distance away, decreases rapidly. Medical applications which want to perform short radius, it may be used in the frequency range 1 MHz to 10 MHz as a frequency, while the GHz (109 Hz), it is widely used in many applications where the sound waves that travel through the air, not in the form of energy that can be converted into energy supplied to other topically Pasco.By shaking back and forth, which causes the sound waves dissipate the ultra sonic district, in the air or mechanical energy conversion, energy in the form of another is coming. Called ultra Ultrasonic sensors (Ultrasonic Transducer) sadio khotran in current khotran sadio ultrasonic sensor ultra has several, depending on the. A very common use include:
