Being Quiet to Listen

My refrigerator has a feature for families like ours. It beeps when the door is left open over a set amount of time. This is particularly helpful in households with multiple people, especially during lunchtime when leftovers are being brought out and put back in batches. We don’t realize the fridge door is open, so it beeps to alert us. The problem is I often don’t hear the high-pitched chirp. I’m not sure if it’s the tone or the noise of the kitchen, regardless of the cause, I tune it out and keep making sandwiches.
