A group of international researchers have developed a way to use sound to generate different types of wave patterns on the ...

Crucially, the sound waves — specifically ... This is accomplished by projecting each beam at slightly different frequencies — one at 40,000 Hz and one at 39,500 Hz, for example.

Refraction of sound waves by two layers of air at different temperatures as a result of the change of speed of the sound. When a wind is blowing there will always be a wind gradient. This is due to ...

However, when sound waves are intense enough, they can interact nonlinearly, generating new frequencies that were not present before. This is the key to our technique: We use two ultrasound beams at ...

This causes the tissue to expand and contract, creating vibrations which can be picked up as ultrasonic sound waves by sensitive detectors. Different materials and molecules inside the tissue ...
