Industrial robots use microphones (acoustic sensors) to accept spoken orders and distinguish unusual sounds in their surroundings. If a piezoelectric sensor is included, it can detect and reduce vibration-induced noise, as well as prevent the robot from misinterpreting speech orders. Advanced algorithms...
How does DTS work? Distributed Acoustic Sensing — How does the intelligent Distributed Acoustic Sensor (iDAS™) work? How is Silixa’s iDAS different from other distributed acoustic sensors? What are distributed sensing systems used for? See also Principles of Distributed Temperature Sensing Silixa...
The waves are typically generated by a controlled source such as explosives, a weight drop, or a vibrator truck. As these waves travel through the Earth, they are reflected and refracted at boundaries between materials with different acoustic properties....
Other types of Piezoelectric sensors include: •Piezoelectric microphones. •Piezoelectric pickups for acoustic-electric guitars. •Sonar waves. The sound waves are both generated and sensed by the piezoelectric element. •Electronic drum pads. The elements detect the impact of the drummers' stic...
Different types of electromagnetic signals are generated between electronic devices, such as radiated electromagnetic waves, conducted electromagnetic signals, and voltage, current, and radio wave interference on power lines. These signals can interfere with each other, causing electronic equipment to not ...
"But it's not just small animals and insects that can use this information, but humans too,Hadany said. All they need is the "right tools-such as sensors that tell growers when plants need watering".This could prove particularly beneficial in the agriculture industry, as researchers noted ...
NOAA’s Acoustic Monitoring Project has been using the Sound Surveillance System to listen for changes in ocean structure like ocean currents or volcanic activity. Most of the sounds recorded are common and of no concern. One sound , identified in 1977 by US Navy “spy” sensors, was odd. ...

Phased arrays are multiple sensors that act together to produce a desired sensor pattern and can be steered electronically simply by adjusting the phase of the signals to each individual element.
How are acoustic sensors used in healthcare? Acoustic sensors in healthcare can monitor bodily functions such as breathing and heart rate or help in diagnostic procedures like ultrasound imaging. 7 What does acoustic mean in terms of music? In music, acoustic refers to sound produced through natu...
