Is There Any Relation Between Hearing Loss And Noise In Ear?

I have hearing loss which requires hearing aids. I put them on as soon as I wake up in the morning, and I do not remove them until I go to bed at night. Over the years, I have noticed that while lying in bed at night, I hear a melodious group (choir) singing, I can t make out the words, and my husband can t hear it at all. We changed bedrooms from the second floor to the basement, and I don t hear the singing any more. However, I was wakened from a sound sleep by what sounded like a vibrating cell phone. I woke my husband up to answer his phone, but he assured my no on was calling. I have always assumed the noises had something to do with my hearing loss and not a change in my mental status. Do I have any reason to be concerned?
