I used to years ago when we had AOL & could do those You've got mail because I did the Powerpuff Girls Mojo Jojo lol Anybody use that back then? Now I don't bother with any sound for dings.
Annoying dings and dongs, while you are talking to people or streaming, can be a butthole. My LAptop notifications are on for DIscord and my other PC goes to silent while it's activated to not go off.
I do on my phone but I don't on my computer. I'm in the process of trying to find a different job so I've been keeping my phone on me a lot more to make sure I don't miss a phone call after I've applied somewhere.
My PC is mostly all muted sounds and my phone is very selective with what goes off via a noise. I try my best to only hear things that may need immediate attention or are otherwise important. So stuff like social media, emails, and nearly all my non-messaging apps, are things that I either don't want to hear or I will likely end up checking anyway soon (like email).
Laptop, no. For my phone, it depends on the time. Throughout the day, I will usually have the notification sounds enabled and then I will silence it at night. I use the horn sound on iPhones for text messages which I love hearing lol
My laptop is on my computer desk in the family room, so having sound on would bother anyone in the vicinity. If I need the sound and someone is home, I use my earbuds. So no, I don't use the sound for notifications.
