Yes.
A few years ago, my father passed away in hospital in the middle of the night (it wasn't expected). I had also put off seeing him that day due to concerns for my mothers health. Me and my mother had made plans to see him on the day he passed in the morning. I received multiple calls from the Doctors and Ward nurses at the Hospital but didn't catch them as I had a headset on at the time watching a film. Whilst it spared me the pain of trying to rush to the hospital over 6 km away and still failing to see him one final time. It ultimately caused a certain level of concern and fear that I will miss out on stuff I need to be alert over, such as my mothers current health now. Since I don't want a headset to block fan noise etc from the gaming PC, I need ears only to hear, and that means speakers on the lowest volume, but to hear those I'd need a much more silent system. Hence, a few years ago, my quest for low noise/silence.
Could always put your mobile on vibrate.
