Not illustrated. 1915 edition. Excerpt: ...and gave forth different sounds, each planet according to its position in the musical scale. The harmonious intermingling of these sounds produced melodious music--the music of the spheres--which, however, mankind could not hear, on account of the loudness of the sounds and the smallness of the human ear. This theory has been often revived, and crops out a number of times in the plays of Shakespeare. Physics The up-to-date instructor in physics never fails to use the Victor instrument to demonstrate before his class in science the principles of sound involved in its construction. It may be made a subject for demonstration in one or more recitations. The Victor has attained its present perfection as an instrument for reproducing sound because it conforms absolutely, in its construction, to the laws of sound. A review of the fundamentals reminds one that sound is divided into noise, and musical sound; musical sound being the result of the periodic vibration of a sonorous body. This vibrating body (the source of sound) produces pulsations in the air, which take on a shell-like form. These pulsations are commonly known as sound waves and possess the physical qualities of reflection, refraction and diffraction. Musical sounds differ in loudness, or amount of sound, determined by the amplitude of the wave; in pitch, or highness, or lowness of the tone, determined by wave length; and in character of sound, determined by the form of the wave. Eecording is measuring the wave amplitude, length, and form, by means of setting in vibration a needle which records sound waves in a lateral groove in a disc made of sensitive material. From these discs, sub The recording disc makes 78 revolutions per minute. In playing a record, the original pitch of the sound is...show more
