摘要:

Experiments show that the brain of people of ordinary musical endowment, when unsophisticated, enables them to esthetically appreciate melodies that are even more mistuned than the equally tempered scale.

摘要:

A recently published article states that “a composing machine employing a random probability system based upon Stephen Foster songs may be developed ….” Later the authors make the categorical statement: “The resulting music [i.e., produced by the machine], while new, sounds like Stephen Foster music.” However, because of many errors in notes and rhythms and a failure to comprehend musical design, the output of the machine bears no resemblance whatever to the songs of Stephen Foster. A possible alternative method of mechanically simulating Foster's style is suggested.

摘要:

The velocity of sound was measured in dissociating dinitrogen tetroxide. These measurements were made over a frequency range of 20 to 800 kc and pressure range of 1 to 70 cm Hg giving a frequency/pressure range of 0.0217 to 60.8 Mc/atm. The temperature range covered was from 0° to 50°C. At 20°C and 10 cm Hg the velocity change was 4% over the frequency range stated and the relaxation time was 1.72 μsec.

摘要:

The amount of cavitation produced in an ultrasonic generator depends on factors such as tank geometry, water height, and continuous‐operation time. Some typical results are presented, which may help to explain the quantitative variability found in, for example, industrial cleaning and biochemical applications.

摘要:

The manufacturing procedure for mixtures containing a resin, tungsten, and rubber powder, are described. The attenuation and elastic constants are measured at 1 Mc and compared with values predicted by an earlier theory.

摘要:

Interference waves resulting from an impulsive source show the same characteristics in a favorable water layer as those described by Bobber for sine wave sources. Recent work in prospecting geophysics on dealing with this phenomenon may apply to problems of underwater sound as well.
