Since babies' cries can reach volumes of more than 100 decibels, it is probably best that you're protecting your ears when exposed to the sound for an extended period.
The sound of your baby crying can be incredibly distressing for a parent. We hate to be the ones to break this to you, but that is kind of the point. Your baby is crying because it is upset and wants something from its parent, so it needs to do everything within its power to get that point across to you. Early on in life, the only way it knows to do that is to scream at you.
On some occasions, no matter what we do to soothe our babies, nothing works. On those occasions, you can almost feel as if you are going insane. If you have felt like that, don't worry, you are not alone. Far from it. LifeHacker reports that one Redditor admitted to having feelings of "anger, despair and even violence."
No matter how we feel, our ultimate aim when our babies are screaming non-stop is to figure out what's causing them to be so upset. However, have you considered what damage the cries might be doing to you? It turns out that the sheer volume a baby's cries can reach can be damaging to our ears. Some can cry as loudly as 100 decibels, which can cause hearing damage after prolonged exposure.
To put it into perspective, 130 decibels is the amount of sound an airplane makes when it takes off, and one study recorded a baby's cry at 120 decibels. Ouch. The easiest solution to this is to buy yourself a pair of noise-canceling headphones. While some experts argue that they don't protect against higher frequency sounds, such as a child crying, there are parents who absolutely swear by them.
What we have to stress at this point is when you should employ your headphone tactic. We would definitely not recommend popping them on before you take a nap so baby doesn't wake you, not unless someone else is listening out should they need something. If you're tending to the baby and can see if they are still crying, pop them on. Your ears will thank you for it in the long run, and it will make the situation less stressful in the moment.
