When you make noise

So I walk into an audiology office cause my hearing aid won't stop squealing. The lady hears me at the front desk and ask me to wait as she checks a patient out. As I'm waiting to let her know I need to see someone about fixing this noise, the audiologist walks out. She ask one of her older patients "is your hearing aids turned on?" I smile but she doesn't see me and she isn't associating the noise to be me. The lady at the front desk is trying to get her attention and keep checking the patient out. It quite hilarious to me and I wasn't going to say anything at all because frankly I wanted to see how good her hearing is! Those who hear well are able to locate from which direction the sound is coming from so I've been told cause I can not do that nor can I hear the actual squealing. What I hear is mostly sounds fading in and out. Needless to say, the doc had to be told it was me and I proceeded to tell her "I'm here to get this very issue fix!". She smiled and made her way back to her office. I know it's going to get taken care of cause she left a patient in her office. She knew high pitch squeal probably was driving everyone who could hear, insane. Which leads me to ponder this thought...."When you make a noise or some noise, you get everyone who can hear the noise, attention." The only thing you have to focus on is what type of noise are you making?" Is it a noise that comforts or soothes? Is it loud enough to cause people to go into action or soft enough to be ignored? Have you been making the same noise for so long that no one notices? Or do you need to change the noise or the people who hears it? Cause frankly, what I witness in this doctor office was pretty much all of the above. What I took away from the experience was more than I anticipated because after all, I'm trying to silence the darn thing!!
