PRESENTATION
USES OF ULTRA
SOUND WAVES

3. • Ultrasound is an oscillating sound pressure wave with a
frequency greater than the upper limit of the human
hearing range. Ultrasound is thus not separated from
'normal' (audible) sound by differences in physical
properties, only by the fact that humans cannot hear it.

USES OF ULTRA
SOUND WAVES

5. Ultrasonic cleaners are used
at frequencies from 20 to
40 kHz for jewelry, lenses and
other optical
parts, watches, dental
instruments, surgical
instrument ,diving
regulators and industrial parts.
An ultrasonic cleaner works
mostly by energy released
from the collapse of millions of
microscopic cavitation near
the dirty surface. The bubbles
made by cavitation collapse
forming tiny jets directed at
the surface

CLEANING

6. Similar to ultrasonic
cleaning, biological
cells including bacteria can
be disintegrated. High power
ultrasound
produces cavitation that
facilitates particle
disintegration or reactions. This
has uses in biological
science for analytical or
chemical purposes and in
killing bacteria in sewage.
High power ultrasound can
disintegrate corn slurry and
enhance liquefaction and
scarification for higher ethanol
yield in dry corn milling plants.

7. The ultrasonic humidifier, one
type of nebulizer is a popular
type of humidifier. It works by
vibrating a metal plate at
ultrasonic frequencies to
nebulize (sometimes incorrectly
called "atomize") the water.
Because the water is not
heated for evaporation, it
produces a cool mist. The
ultrasonic pressure waves
nebulize not only the water but
also materials in the water
including calcium, other
minerals, viruses, fungi,
bacteria and other impurities.
Illness caused by impurities that
reside in a humidifier's reservoir
fall under the heading of
"Humidifier Fever".

8. In ultrasonic welding of
plastics, high frequency
(15 kHz to 40 kHz ) low
amplitude vibration is used to
create heat by way of friction
between the materials to be
joined. The interface of the
two parts is specially designed
to concentrate the energy for
the maximum weld strength.

9. Ultrasound has been studied
as a basis for sonic weapons,
for applications such as riot
control, disorientation of
attackers, up to lethal levels
of sound.

10. Ultrasound has become a
common therapy for a
number of clinical conditions:
sprained ligaments, inflamed
tendons and tendon sheaths,
lacerations and other soft
tissue damage, scar tissue
sensitivity and tension,
varicose ulcers, amputations,
neuromata, strained and torn
muscles, inflamed and
damaged joint capsules,
fasciitis, and delayed-onset
muscle soreness. Recent uses
include the accelerated
healing of fractures, muscle
injury, and thrombolysis
Applications in
medicine

11. It is an ultrasound-
based diagnostic imaging
technique used for visualizing
internal body structures
including tendons, muscles,
joints, vessels and internal
organs for possible pathology
or lesions. The practice of
examining pregnant women
using ultrasound is
calledobstetric sonography,
and is widely used.
Diagnostic
sonography (ul
trasonography)

12. Ultrasound is applied using a
transducer or applicator that is
in direct contact with the
patient's skin. Gel is used on all
surfaces of the head to reduce
friction and assist transmission of
the ultrasonic waves.
Therapeutic ultrasound in
physical therapy is
alternating compression and rar
efaction of sound waves with
a frequency of >20,000
cycles/second. Therapeutic
ultrasound frequency used is 0.7
to 3.3 MHz. Maximum energy
absorption in soft tissue occurs
from 2 to 5 cm. Intensity
decreases as the waves
penetrate deeper.

ultrasound

13. The device allows us to
connect 2 sensors with RS-232,
TTL or RS-485 interfaces, which
are one of the most common
interfaces in underwater
sensors. Its frequency range is
from 2.412 GHz to 2.472 GHz.
These values correspond to
the spectrum used by devices
operating under the IEEE
802.11b/g standard at 2.4
GHz. The used antenna is a
monopole with 2 dBi of gain.
Ultrasonic as
means of
communication

14. Ultrasound technology is an
area of increasing application
in the food, drug, and device
industries. Ultrasonic
techniques are presently
utilized for applications
ranging from bonding and
sealing of thermoplastic
packaging to medical
diagnosis. This ITG serves as an
introductory issue for future
ITGs that will describe specific
applications of ultrasound in
the food, drug, and medical
device industries.

ULTRA SOUND TREATMENT FOR DRUG ADDICT

15. • Ultrasound is used in many
different fields. Ultrasonic
devices are used to detect
objects and measure distances.
Ultrasonic imaging is used in
both veterinary
medicine and human medicine.
In the nondestructive testing of
products and structures,
ultrasound is used to detect
invisible flaws. Industrially,
ultrasound is used for cleaning
and for mixing, and to
accelerate chemical processes.
Animals such
as bats and porpoises use
ultrasound for locating prey and
obstacles.
