As long as the intensity of the auditory stimulus Is less than 6 decibels, the laten.
cy of the galvanic skin reflex is relatively great (average 3.1 Bec.), failing to 1.7
sec. when the threshold value is exceeded. The reactions show a very marked
change when the intensity is raised to 70 db,, at which point disturbances of the
alpha rhythm are frequently obl3erved. The Inhibition of this rhythm is of shorter
duration with subliminal than with supraliminal stimulation. It Is Concluded that a

Abstract: Explanation of new methods for measuring hear:Ing, based on the use
of conditioned reactions to sound by humane. Data are given to shuw
that the absolute hearing tlu~esholdB and differential limits fcr the
frequency and iti.tensity of pure tones can bemeasured in humans with
the,aid of these reactions with the same reliability, as when using
the v4rbal response; in some cases one observes conditioned re-
flexes', which appear to be subthreshold cneB w-Itbin lJmif,13 of one

,rhe article describes tile results of studying tile quanti!ative indices of the func-
tion of the acoustical analyser in man - the absolute and differential thresholds -
on the basis of various reactions. For this aim, in addition to the conventional
verbally conditioned reactions, use was made of conditioned eye-lid movements,
skin-galvanic, and electro-cortical reactions. All the reactions involved in the
study of quantitative indices of the acoustical analyser activity were classified into
three groups: (1) verbally conditioned reactions, (2) reactions elaborated with an
unconditioned reinforcement and (3) reactions developing 'on the spot', i.e. those
which do not require either unconditioned reinforcement in the experiment or
verbal instructions. It has been found that: (1) Absolute auditory thresholds and
differential threshold for the f requency and intensity of pure tones can be measured
in man with the help of these reactions as reliably as by meann of verbal respons-
es. (2) In some cases conditioned reflexes have appeared which are subthreshold
within I to 6 decibels in relation to the verbal response. (3) Changes in absolute
and differential sensitivity reaching 25-30 decibels can be discovered, depending
on the conditions under which the reactions occur. (4) Preliminary excitation of
certain parts of the motor system is one of the important conditions determining
the changes in the analyser sensitivity. The article discusses the possible mecha-
nisms determining the variability of ~he analyser parameters and their conformity
with the nature of the activity in question. The author points out the weakness of
those schemes of analyser activity which ignore the significance of two-way con-
nections in the integral organism.

It is known that the main juarititative cha rac!v ris tics of hearing in inan can be Ob-
tained by so-called psychophysi(:al metiiods. In thuse methods the responivs to
sound stirnuli are based upor the use of verbal instrm.-tions, Th"4 paper gives a
description of methods of measurements of hearing based upon the use of other
different responses to sound stimuli. A set of different conditioned responses was
uslA (galvanic-skin reflexes, eyelid reflexes, electro -cortical and OcUlonlotor re-
actions). The data obtjined by these methods show the following: (1) absolute audi-
tory thresholds and difference Limens for frequency and inteiwity of pure tones call
be measured with the same accuracy by these reactions as by verbal responses;
(2) in certain cases conditioned reflexes subliminal to the verbal response in the
range of I to 6 db. may 6a detected; (3) changes of absolute sensitivity, attaining
25 to 30 db. and dependent on the conditions under which the reacW)ns take place,
can be detected. The present data of hearing mea-qurements obtained by means of
different responses are considered as highly chnracturistic of the procest; of sound
discrimination in man and animals.

TITLE: Regulation of a Ifeural Pulse Stream in the Auditory System
PERIODICAL: Akusticheskiy zhurnal, 1960, Vol~ 6, No~ 3, pp, 299-301,
TEXT: On the basis of electric-phyaiological examinations of reflexes of
various parts of the auditory system (cochlea, geniculate body, cerebral
cortex) of living beings the author studies the problem of regulating the
current of primary impulses in the organism, which permit the "informativoll
perception of sound signals. Fig. 1 illustrates the electric reactions 0t
various parts of the auditory system to a sound signal of a duration of
10 msec, The electric oscillations have amplitudes of 50 4Y. The dependenOF1
of these amplitudes on the sound intensity is shown in Fig~ 2. The first
nerve stimuli in the cochlea attain amplitudes of nearly 100 pv (at 80
decibels) and tire largely dependent on the sound intonsity (curve 1). The
amplitudes of the first positive wave are not higher than 10 v. At intensi-
ties of more than 40 decibels they are practically no longer dependent on
the sound intensity (Curve 2).. The first pocitive navc in the auditory

area of the cortex attains amplitudes of up to 70 ~tv, and the dependence
of the amplitudes on the sound intensity decreases rapidly (Curve 3), Next,
the author discusses special electric reaction dia,~7,rams which were taken
under different conditions, and studies the effects of disturbances
(e.go, anesthesia, partial destruction of the auditory area of the cortex)
The results discussed here wereq for the major part, publinhed by
Ya~ A. Al~tman, They illustrate the importance of the various ways of im,
pulse regulation in the organism. 1) The current of impulseeresulting
from an acoustic stimulation in a nerve is limited, The secondary current
caused by this current are also limited. 2) The current of impulses result-
ing from the action of a special system of (reverse) conneations radiating
from the center is limited. 3) The current of impulves in the higher
ranges of the auditory system changes under the action of sections of the
central nervous system outside the auditory system. The author discusses
two znechanism8 of the regulation of Information tranomitted by currents
of nervous impulses which may occur in the auditory system under the action
of sound. The first mechanism consists in a change of' the participating
elements, and the second one in a change of the level of the char;.,cteristic.

Title Problem of the stability of planar convective movement of a liquid
Periodical Zhur. tekh. fiz., 25, February 1955, 351-357
Abstract Earlier the author investigated (ibid., 2', 1838, 1953) the sta-
bility of stationary convective movement of a liquid between ver-
tical parallel planes heated to different temperatures or between
planes arbitrarily oriented relative to the gravitational field,
the investigation showing that for various angles of Inclination
the crisis of stationary movement occurs for different causes;
further, this problem is of interest for its own self since it re-
lates to the practical important problem of heat transfer through
liquid or gas layers. In the present work the author considers
the convective movement of a liquid in the portion of a planar
slot remote from the ends which is formed by two planes beTween
which is maintained a constant temperature differ;nce T. He drives

threshold of convection is a special case of the occurrence of
turbulence, as noted by V. S. Sorokin (Prikl. mat. i mekh., 18,

ABSTRACT: Forced vibrations in an elasto-plastic system beyond
the elasUc 11init are considered. Friction and hysteresis
are taken into ac~--.ount. The resonance properties of such
a 3ystem are discussed and compared with tile exDeritiental
data given in Refs. 1 and 2. The equation of motion of a
point under the action of an elasto-:1)lastic force F(x)
and an external forcerG sin (wt + 0 is of the following
form
inx + Xx + F(x) = G sin (wt + (p) (2)
v-.,here X is the coefficient of friction and F(x) is given
by:

the equation of heat cenduction - the tough diosiration and

in the case of the prooence of an exterior mairnetic field
which is vertical to the surfaces. If 'lie linear dimensions
of the surfaces -are cufficiently Creat compaxed with the
distance between them, then an accurate, solution of the above-
-mentioned dimensionless equation3 can be determined which
describes the zteady solution in the 1~art dli,.;Lariced from the
ends of the Eap formed by 'the surfaces. 4his notion has t`-e
following pecul.arities: 1) The velocity v is always perallel
to the z-axi3. 2) The temperature T d~,,pends only on X. 3) The
field-vector 11 is situated everywhere in the surface (X--),
viz. it holds Hy = 0- 4) All values do not dc~Lend on y
(plane problem) and t.tcept pressure, neiti-er on Z. In this
case the z-axis is parallel to the slirfaces and the x-axi3 is
vertical to them. The authors determine here the distribution
of temperature, velocity and field st~-ength on the cross
section. Fir6t, T = -x is found. Also the terris for the

ABSTHACT: The present paper solves the problem of the closed convective
boundary layer in a horizontal circular cylinder. The surface
of the cylinder with a radius R is kept at the temperature
To = 0 sin x, where x denotes the coordinate along the circle and
(9a time-constant amplitude. The temperature assumed to be
homogeneous in the core is considered to be the temperature of
refdrence. The core is assumed to rotate as a solid at the rate
v O)r, where the anffular velocity W is required. The
f
boundary layer equations (in disregard of the curvature of the
layer and with introduction of dimensionless variables) are:
