Types of Sound Waves The three basic types of sound waves are classified based on whether they are audible to humans. Audible sound waves are those sound waves that humans can hear. Infrasonic waves are sound waves that are too low-frequency for humans to hear. And ultrasonic sounds waves ar...
Fire is far and away the number one cause of property damage. For years the humble fire detector has been beeping away at the first sign of smoke in the home, but there are several types of pollutants that can threaten our home environment and air quality, all which could lead to propert...

object and returns back to the same path which is detected by the ultrasonic receiver. The ultrasonic sensor utilizes the time of flight (TOF) technique to measure the distance of the object. Ultrasonic waves travel faster than the speed of audible sound (i.e. the sound that humans can ...
This was done in six stages of decreasing fineness with the last one being in the range of 0.25 μm. After polishing, the samples were placed in an ultrasonic bath to remove the dust and diamond particles left on the surface or in the porous structure. 2.3.1. The LEXCOM instrumented ...
Types of Goniometers By Faith Davies A goniometer is an optical tool used to measure angles. Goniometers have a variety of uses in science and industry, and there are many types. Audio Goniometers In sound production, a signal contains stereo or mono qualities, which relates to the ...
Amplitude –In sound waves, amplitude refers to the magnitude of compression or expansion experienced by the medium the sound wave is travelling through. High amplitude means loud noise. Low amplitude means low sound. Pitch –Pitch/Frequency in a sound wave refers to the rate of the vibration ...
When your fingers move up close, they break invisible beams that pass over the surface of the screen between LEDs on one side and photocells on the other.Surface Acoustic WaveSurprisingly, this touchscreen technology detects your fingers using sound instead of light. Ultrasonic sound waves (too ...
