How to Build an Infrasound Generator Circuit

 · It is said that places haunted with ghosts and paranormal forces are engulfed in a strange environment. Such places are found to be surrounded with frequencies below human audible range, infra sound range. A simple experiment of creating similar effects using an infrasound generator can be conducted in your house itself. Learn the setup procedure here in this Bright Hub electronics article.

Displacement Sensors / Measurement Sensors

3. Ultrasonic Displacement Sensors. A transmitter sends ultrasonic waves toward an object, and a receiver receives the reflected waves back from it. This type of sensor determines the distance by calculating the relationship between the time required for the ultrasonic waves to be sent and received, and the speed of sound.

Ultrasound frequencies | Radiology Reference Article ...

Ultrasound frequencies in diagnostic radiology range from 2 MHz to approximately 15 MHz. It is important to remember that higher frequencies of ultrasound have shorter wavelengths and are absorbed/attenuated more easily. Therefore, higher frequencies are not as penetrating. This explains why high frequencies are used for the superficial body ...
