Noise Reduction In Hearing Aids
1,312 words
... en adjusting for both noise, and sound
quality. The most versatile type of ASP (automatic
signal processor) comes from PILL circuitry that
can provide either a BILL or a TILL response. In
order to accomplish this, the instrument must have
a minimum of two channel compression. (Tobin 1997)
In effect, the audiologist can choose which type
of processing better suits his client, while
taking into consideration the subjective needs of
his client. Presumably, PILL type hearing aids
cost more than ...

Magnetic Field Large Amount
1,319 words
A transformer is a device that raises or lowers
voltage and is used mostly with alternating
current, or ac. A transformer has no moving parts,
is simple, rugged, durable, and can be up to
ninety-nine percent efficient. Cities use a large
amount of power, and power is based on the amount
of current in electricity. A transformer works by
changing the amount of voltage and current of
electricity. When voltage is increased current in
electricity is decreased or if voltage is
decreased current in ele...

Magnetic Anisotropy Of Fine Particles
377 words
Magnetic Anisotropy Of Fine Particles" In nature,
single domain particles are magnetized to
saturation, where the magnetization has an easy
axis, or several easy axes, along which it prefers
to lie. In this case the total internal energy is
minimum. Rotation of the magnetization vector away
from the easy axis is possible only by applying an
external magnetic field. This phenomenon is called
magnetic anisotropy. Thus, the term magnetic
anisotropy describe the dependence of the internal
energy on ...

The 20 th century saw a great many new discoveries
regarding celestial phenomena in the universe. One
of these entities, which has only recently been
encountered, is the Black Hole. These are formed
when a star which has consumed all its fuel
collapses in on itself, eventually turning into a
black hole with infinite density and zero volume
and an immensely powerful magnetic field. We are
unable to see black holes even with the most
powerful telescope, because their gravitational

HISTORY OF COMPUTERS Historically, the most
important early computing instrument is the
abacus, which has been known and widely used for
more than 2, 000 years. Another computing
instrument, the astrolabe, was also in use about
2, 000 years ago for navigation. Blaise Pascal is
widely credited with building the first digital
calculating machine in 1642. It performed only
additions of numbers entered by means of dials and
was intended to help Pascals father, who was a tax
collector. In 1671, Gottf...
