Light and sound waves - OCR 21st Century
The process is very similar to ultrasound imaging, however the sound waves used are within normal hearing range, and they are used to identify objects rather than internal structures. This ...

The science of noise colors: why white noise makes you sleepy and blue noise helps you focus
"The color names for different types of sounds are based on an analogy between the frequency makeup of sound waves and light waves," Ashish Shah, an audiologist at The Hearing Care Partnership ...

Diffraction of Light by Ultrasonic Waves, Oblique Incidence and Sound Intensity
We have now observed for this small sound wave-length that, when the sound intensity is slowly increased, the number of these maxima diminishes. Further, the emphasis appears to shift towards the ...
