In hospitals equipped with “radio-pillows” in which telephones are concealed within the pillows, the music may remain continuous until the patient falls asleep. Many people have developed the habit of falling asleep to radio music or turning it off when they become sleepy. Radio programs are not recommended as slumber music. The musical program should use the old favorites or meal-time music selections (See Chapter VI) at a very low volume. Loud and stirring music before bed-time has been known to result in vivid auditory dreams, and should be avoided.[24] THE BEDSIDE RADIO More than any other single factor, the radio has increased musical knowledge and appreciation in this country. The programs of Bing Crosby and Alec Templeton have great popular appeal because of the extensive preparation, humor, and showmanship contained in them. Yet these programs never fail to include classical music, and introduce serious music to those who would not freely choose to listen to it. But more than any other single factor, the improper use of the bedside radio can make patients hate music. The most passionate lovers of music will admit that it is possible to have too much music of the same kind for peaceful consumption. In hospitals with large wards, two or more radios may be found tuned in to different programs, and the desire to share the program with others means excessive volume. In those institutions which do not possess a public address system radios should be permitted on the wards but certain rules should be observed. The volume should be controlled so that patients who are not interested do not have to suffer. The volume should be one that makes the signal just audible to the owner and to those of his neighbors who wish to listen. For several hours of the day interludes of silence should be observed by all owners of radios. In hospitals with a loud-speaker system, all radios should be turned off during the hours of its operation. In hospitals for the chronically ill, such as tuberculosis sanatoria, where the musical tastes on the ward may run a wide gamut, a schedule should be arranged for those possessing radios, allotting certain periods of the day to each owner and arranging the sound distribution so that two or more radios may be turned on simultaneously but spaced so far apart that the resulting sound will not result in a form of punishment for those caught in between or not fortunate enough to own their own radios.
