How long should radio broadcasts generally last according to best practice standards?

The best practice standard for the duration of radio broadcasts is 30 seconds. This duration strikes a balance between delivering concise and clear information while allowing enough time to convey important messages effectively. In emergency situations or for urgent announcements, brevity is crucial to ensure the message is received attentively without overwhelming listeners. A 30-second window often provides sufficient time to outline key details and instructions necessary for the audience to act appropriately. This timeframe helps maintain listener engagement and ensures that essential information is communicated efficiently. Longer broadcasts may risk losing the audience's attention or could lead to an information overload, diluting the effectiveness of the message. Therefore, aiming for broadcasts around 30 seconds aligns with best practices in communication.
