The speaker in the ward is an essential facility in a medical institution. Its main function is to provide patients with various information, such as doctors' diagnosis and treatment plans, nurses' care arrangements, ward regulations, etc. The loudspeaker volume is appropriate and can effectively transmit information, allowing patients and family members to understand the diagnosis and treatment status and care arrangements in a timely manner, and improve the quality and efficiency of medical services.

In addition to transmitting information, the speakers in the ward also play another important role, which is to regulate the patients' emotions. Patients who are hospitalized often cannot help but feel lonely, helpless and afraid. In this case, medical institutions can play healing music, lighthearted jokes and condolences through speakers to reduce patients' discomfort and psychological pressure, and enhance their confidence in treatment and enthusiasm for recovery.

It should be noted that when using ward speakers, the hospital should protect the patient's privacy as much as possible. For example, patients’ diagnosis and treatment information cannot be disclosed through loudspeakers, and patients’ personal information must be avoided under any circumstances. In addition, the loudspeaker volume and playback content should also be moderate, not only to convey information, but also to avoid affecting the patient's rest and treatment. In short, as one of the important facilities of medical institutions, speakers need to be carefully managed and used.
