How long does it take a person on hold to become annoyed?

The time it takes for a person on hold to become annoyed can vary, but research suggests it typically occurs within 30 seconds to a few minutes. Factors influencing this include the individual's personality, the context of the call, and the quality of the hold music or message. Generally, longer wait times and repetitive or low-quality audio can increase frustration levels. Most callers prefer to speak to a representative within a couple of minutes to maintain their patience.
