What is the most appropriate action when assisting a person who is hearing impaired?

The most appropriate action when assisting a person who is hearing impaired is to ask the customer how he would like to communicate. This approach respects the individual's preferences and acknowledges that each person may prefer different methods of communication, such as speaking clearly, using written text, or employing sign language. By asking the customer directly, you create an inclusive environment that fosters effective communication and makes the individual feel valued and understood.

In contrast to this preferred method, the other options do not take the customer's needs into account. Speaking loudly and close to their ear might not be effective, as many people with hearing impairments have varying degrees of loss and might not benefit from louder speech. Relying on someone who knows sign language without first consulting the person can lead to assumptions that may not align with their preferred communication style. Finally, ignoring their communication preferences is not only disrespectful but could also hinder effective service and support. Engaging the customer by asking how they wish to communicate is the best way to ensure clarity and respect in the interaction.
