Speeds of Sound in Various Tissues:

Air: ~ 331 m/s (slowest)

Fat: ~ 1,450 m/s or 1450 m/us

Water: ~ 1,480 m/s

Soft Tissue: ~ 1,540 m/s (average)

Muscle: ~ 1,580 m/s

Bone: ~ 3,500 m/s (fastest)

,hint: As a general rule, sound travels fastest in

solids, slower in liquids, and slowest in gases

increase density in the air that

decreases the propagation speed

Denser=slower (D&S different direction)

increase in stiffness (as in bone or metal)

increase in propagation speed (S&S same

direction)

stiffer=faster

Frequency 2.0-2.5 are for

deeper structures, increasing the depth and

decreasing the axial resolution(see two

structures)

, The technician receives greater depth

penetration but less axial resolution•

Frequencies of 5.0,7.0, and 10.0 are for

Surface structures that decrease the depth and

increase the axial resolution

Technician receives less depth penetration and

increases the axial resolution

Ultrasound

is above the audible range of human hearing-

ultrasound is above/greater than 20KHz or

20,000Hz

-Sound waves beyond the audible range
