Echolocation

Application of sound to people

-is a technology that uses high frequency sound waves.

• Frequency is the number of wavelengths that pass a fixed point in one second

​

ULTRASOUND

Ultrasound imaging is a technology that uses high frequency sound waves to create images.
Ultrasound imaging depends on sound wave-object .

• The machine generates sound waves that are reflected by parts of the body.

• The reflection of sound waves creates echoes.

• The echoes are received and processed into images.

ULTRASOUND TECHNOLOGY

Ultrasound Technology in Treating Diseases

Ultrasound technology is used to diseases.

Sound waves are absorbed by:

• kidney stones, until they are enough to exit the body.

• cancer cells, which are warmed up and destroyed.

• It also can clean large pieces of machinery.

Cleaning lenses

• It cleans small items, such as lenses, jewelry, watches, and surgical tools.
