Technical question about hearing loops...

What's the average range for a hearing loop? For example, would a deaf person need to be really close to wherever the microphone is?

Would e.g. a supermarket potentially need multiple hearing loop systems?

Working on an article about deaf people at the moment and want to learn as much as I can about this technology.
