Q.21.
Dolby B-type noise
reduction is the
original Dolby system
designed for consumer
tape recorders. It is
included in all but the
least expensive cassette
machines today and is
used in the preparation
of the vast majority of
pre-recorded cassettes.
It is also incorporated
in many stereo VHS
videocassette recorded
to improve their (mono)
linear audio tracks and,
in a modified form, in
Dolby Surround decoders.
Dolby B-type provides 10
dB of noise reduction at
the higher frequencies
where tape hiss
predominates.

strength, and resistance
to creep. This 63-37

point of the alloy,
where the alloy behaves
like a pure metal having
a single melting
(solidification)
temperature (176�C /
349�F).

. Speed of sound in a
structural material
varies directly with the
square root of the
modulus of elasticity
and inversely with the
square root of the
density. The speed of
wood varies strongly
with grain angle since
the tranverse modulus of
elasticity may be as
small as 1/20 of the
longitudinal value.
Thus, the speed of sound
across the grain is
about one-fifth to
one-third of the
longitudinal value. The
speed of sound decreases
with increasing
temperature or moisture
content in proportion to
the influence of these
variables on the modulus
of elasticity and
density. The speed of
sound decreases slightly
with increasing
frequency and amplitude
of vibration, although
for most common
applications this effect
is too small to be
significant.
