After “lights out” radios frequently remain on unless supervision is severe. It is true that many of the better programs are heard after nine o’clock. Since some of the late programs are part of American life, it is unfair to the chronically ill to deprive them of this well planned entertainment. Yet there will be some on the ward who will want to sleep, and they should be given maximum consideration. Others should be permitted to keep their radios on at the lowest possible volume, and the possibility of headphone installations should be reviewed. The solution to this problem is possible but expensive. If a record-cutting device is available, the program may be recorded at night and replayed on the following day. PUBLIC ADDRESS SYSTEM Many hospitals have already been equipped with either loud-speaker or headphone installations. For those hospitals which are still in the deciding stage, some of the advantages of each will be briefly considered. Ideally, both speakers and head-phones should be available. This is a luxury in which few will be willing or able to indulge. When head-phones are used, they have a way of getting misplaced, broken or broken-down. Head-phones or listening devices are usually distributed to those patients who are medically eligible. Frequently the attendants are busy and forget to supply them, to the chagrin of the patient. When there are not enough to go around a further source of dissatisfaction arises. Head-phones must be adjusted for proper reception and comfort, and this may become a source of bother to patients or staff. Among the advantages of ’phones are the quietness of wards at all times for those who desire rest. Their use permits maximum focusing of attention on the music because of the exclusion of most other sounds. They become a mechanism of escape from the unwanted conversation of noisome neighbors. When double-jacks or two-channel wiring is used the patient is permitted some choice in music selection. The use of ’phones, however, limits the physical excursion of the ambulatory patient. The use of a loud-speaker system permits those patients not strictly confined to their beds to visit other parts of the ward without interruption in their listening. Some patients enjoy music as a background to conversation or ward activities. The same switchboard may be used for musical programs and hospital announcements, and this may be desirable economically in some institutions. Strategically placed speakers may be channeled exclusively as a call system. Laughter is a communal reaction. We rarely react completely to a radio joke if we are listening alone, but if several people listen simultaneously laughter becomes more pronounced and prolonged. Loud-speaker systems permit patients on the ward to enjoy music as a group. They also permit the greater use of background music. Eating with the encumbrance of head-phones is not desirable.
