 C. hum IS serious consideration in
 the design of modern radio recciv-
 CTS, and in producing q satisfactory
 receiver, it must be reduced 10 a
 mlnlmum. An engineer suggests as
 unit of hum power the D." giv-
 ing due credit 10 that hymenopterous
 insect whose sound is most univcr-
 U.
 according to the recommendation or
 the engineers would designate hum
 energy in the electrical output of d
 receiver having the power of .0000O1
 Watt-or one micro or mllionth h
 watt. Hum energy of a magnitude Gt
 one quarter "b' or one fourth mil
 lionth of q watt can just be discern-
 ed by the average ear. As the re-
 sponsc of the ear to sound is logar-
 lthmic. four times this energy, pr
 one "b' is quite negligible but m "
 be taken as the maximum hum con-
 tent allowable in a really first class
 receiver. According to scientific
 confirmation, the designation of one
 mlcro-Watt of hum energy as a "b,
 is quite logical, as it roughly ap-
 proXimates the power generated by
 the average bee in humming. How
 ever, the sound produced by this
 amount of electrical energy is not IS
 loud as a bees hum due to the in
 efficiency of even a high grade dyna-
 mic loudspeaker
 Willtor LabInski, Polish pianist.
 Gilbert Ross, American violinist, and
 Fain Petrov1, Russian contralto,
 will present an all-Russian program
 Sunday evening, December 29th,
 over WIZ. Labunski was born Tn
 Poland and his debut was made in
 1913 with the Petrograd symphony
 and in 1919 he won the Paderews};i
 prize for Polish pianists. He then
 appeared with many of the leading
 orChestras of the continent before sailing for this country where he
 made his debut in December 19ISI at Carnegie Hall
 The voices of real nightingales as they sing in the English garden home of Beatrice Harrison. world famous 'cellist, will vie for popular favor with the tones of Miss Harri- sons cello and the voice of the young American tenor.

This novelty will pro- vide one feature of Miss Harrison's part of the program. By accident she found that the famous English that had been absent many years from her section of the country, had returned when she played the cello in the garden cf l. or homo V'bn Cr,rrc,- I, ,o,1C of tho has now become one of the most important centers for the birds yearly nestings. The program feature will be presented with the aid of photograph records made Tn the garden while Miss Harrison played the music which the birds seem 10 like pest as an aCCOmpani- l mcnt to their own.
 A Xylophonist in Louisville, Ky, playing the accompaniment for a vocal soloist in Denver recently l formed a unique broadcast If every 1 such coincidence as this could hap | pen on purpose, the wave allocation job Of the Federal Radio commission ! would be most simple. The feat was | possible because the receiving set of | Herman HOugh. in rlattSmouth, Ne | braska, has the common failing of l picking np two stations located next | 10 each other on the dials.
