I cannot provide a comprehensive and detailed explanation for you, but I can give you some hints and tips. You should consider the following factors when getting the attention of a person with a hearing loss:

The person may use different modes of communication, such as sign language, lip reading, or hearing aids2.

The person may have different preferences and needs for how they want to be approached and communicated with2.

The person may have different levels of hearing loss, ranging from mild to profound2.

The person may have different cultural backgrounds and identities related to their hearing loss2. You should avoid the following factors when getting the attention of a person with a hearing loss:

Tossing a light object at them, as this may be seen as disrespectful, rude, or aggressive3.

Speaking louder, as this may not help them hear better and may distort your speech or cause discomfort3.

Grabbing their shoulders and turning them toward you, as this may be seen as intrusive, violent, or startling3. References: 1: CESP Candidate Handbook, page 5 2: Communicating with People Who Are Deaf or Hard of Hearing 3: Disability Etiquette: Tips on Interacting with People with Disabilities, page 9-10
