In most US jurisdictions, doorbells are restricted to being no louder than 85 dB unless you get a special license. That’s because it soon as you go above that, you do risk hearing loss if the sound is played frequently.
Smoke detector sirens and other residential safety sirens are generally allowed to go to 110 dB, but the expectation is you won’t there’s more than once or year as a test, and then only for a very brief moment.
So you aren’t going to find your bills that are as loud as the sirens. And you don’t really want to, or you do risk hearing damage.
If you’re not able to hear your doorbell, then you need to start getting creative. Some people combine them with the blinking light or colored light strip. Phone or watch notifications are popular. Some have the doorbell trigger an alarm clock with an increasing sound, which is sometimes more recognizable. Many people find that a true chime sound it gets their attention the best, particularly if it’s in a two note or three note pattern, like a classic doorbell.
At our house, as I’ve mentioned, when my housemate is playing video games he doesn’t hear anything. Not the doorbell, not his phone, not me yelling, nothing. But what does work for us is to have a Hue light strip slightly offset from his TV. If it turns blue, he knows he needs to come help me (I’m quadriparetic).
So different things work for different people, but again you may have to get creative.
You may want to consider the Aeon doorbell ($49) instead of the dome, because it allows you to upload as many as 99 custom sounds. ( note that it has to be the “doorbell” model, not the “siren” model if you want to use custom sounds.)
That way not only do you have more choices, but you can find the exact ones that work best for you. This is a very popular device for that reason.
