While being deaf or having a hearing impairment is a diagnosis most of us know of, there are still aspects most of us aren’t aware of. A hearing impairment isn’t as simple as not being able to hear. You may still be able to hear, though at different levels. The sound of a train thundering by could sound more like a whisper. In addition, having a hearing aid doesn’t mean the person has complete hearing restored and it’s not a matter of simply turning them up. Areas with a lot of noise, such as a restaurant or cafeteria can be overwhelming to some individuals and conversations can sound simply like indiscernible noises.
