TITLE: A Correlational Method of Measuring the Acoustic Ratio.
(Korrelyatsionnyy metod izmereniya akusticheskogo otnosheni-

(USSR)
ABSTRACT: In considering certain acoustic problems of architecture
of enclosed spacest the concept of acoustic ratio is used
(Ref.1). The present note describes a method of direct mea-
surement of this ratio in an enclosed space and a number of
results obtained using this method are given. Suppose that
in a closed space a linear sound transmitting channel is
working, emitting a sonic signal x(t) . Using the prin-
ciple of super osition f,jr a linear system one can say that
a process y(t5 received at some point within this enclosed
space is described by the expression:
y(t) = x(t - 9) f (9) dQ (1)
0
where f(G) is the response of the system to a 6-impulse.

where ax and Oly are the effective values of the emitted
and received processes respectively and Rxx is the coeff-
icient of autocorrelation of the process x(t) . Eq.(2)
gives the relation between the coefficient of mutual correl-
ation, the autocorrelation function of the emitted signal
and the response of the sonic transmission system to a
single impulse. From these expressiDns it is shown that:

taken by the ith wave and a i = UiI'X where a i are coeff-
icients taking into account the divergence of waves in space
and their absorl-tion on the reflections. Thus, R XY turns
out to be a direct measure of the acoustic ratio. The expe-
rimental part of this work was carried out using the ap?a-
ratus shown in Fig.l. The apparatus c)nsisted of a corre-
lation motor, I (cf.Ref.2) in series with a delay device,2,
and a noise meter, 3. To the radiator, 4, a noise signal
x(t) was applied. T~fte position of the radiator was kepi
fixed. The receiver, 5, cDuld be placed at 7 different
points along the axis of the emitter. At each of these
points R XY ZT) was measured as well as the level of total
sound in the enclosed space, i.e., 20 1- cr The results
of measurements are summarised in 3 figures. The following
persons collaborated: E.L.Feynberg, V.S.Grigor'yev, N.S.
Antonov and V.M.Shatalov. There are 3 figures, no tables
and 3 references of which 2 are Russian and 1 English.

ABSTRACT. The instrument is illustrated schematically in Figure 1.
S is a light source which illuminates two parallel
films n I and n. . The processes to be investigated
g(xI ) and :(x) are recorded on the films along the
91window" having a length D makc ~ 300 mm . The
transparency f(x) of the film n2 as a function of x
corresponds to a time-dependent process
f(t).x = vt , where v is the velocity of motion of
the film during the recording of the signal. The light
transmitted through the superimposed films t1l and n 2
falls on a set of photo cells. The curtent of the photo

moving one of the films with respect to the other, it
is possible to determine the type of the correlation
function. In order to determine the bl)OCtrum of f(x)
it is necessary to express g(x) in the form:
g(x) = cos kn (x - 4) (5)
with different k n If k n 2qu/D , then:
i = BDC cos (k 4 ) (6)
which shows that the amplitude of the output signal is
proportional to the spectral amplitude of the signal
f(x) . The instrument constructed on the above principle
had the frequency range from 1/300 to 3 c/s. The
averaging time could-be as high as 300 sec. Some of the

TEXT- The problem of channel capacity of multipath
communications channels with constant or variable parameters
has been considered by various authors - R.L. Dobrushin
(Ref. 4 - Teoriya veroyatnostey i eye primeneniye, 3, 395,
1958), B.S. Tsybakov ( Radiotekhnilsa i elektronika, 1958, 4,
1427 - Ref- 5) and J. Feinstein (J. Appl. Phys., 26, 219, 1955
Ref. 6). The problem is investigated further in this paper.
It is assumed that the investigated channel is in the form
shown in Fig. 1. The signal x(t) propagates through a
multipath medium by various routes and at the receiver it is
in the form
