low-frequency sound wave

Low-frequency sound waves had the longest range before the underwater signal died off.

No, it did not seem to vibrate when low-frequency sound waves were applied.

A lung flute is a medical device used to clear mucus from congested lungs with low-frequency sound waves.

The ground-based sensors work like sensitive ears to detect very low-frequency sound waves, which radiate outward around the globe over hundreds and thousands of miles.

These include infrasound microbarographs (acoustic pressure sensors) that detect very low-frequency sound waves in the atmosphere produced by natural and man-made events.

Always on, whether the stereo was on or not, ANC took input from two microphones placed in the cabin to analyze drivetrain-related low-frequency sound waves entering the cabin.

Time-Consuming Inspections The inspections will be time-consuming, with the disks removed from the engines and immersed in special tanks for nearly two days while low-frequency sound waves are used to probe for incipient cracks.

His scheme is to cause the collapse of the worldwide diamond market and, in passing, to kill every living thing in Honolulu by means of a convergence of ultrapowerful, low-frequency sound waves emitted from four sites around the Pacific rim.
