Annoying Noise !

[alchemy]

I know this is probably a stupid question. But it has gotten pretty annoying and I just need to ask how to fix it. My phone gives me a notification every time I send a text msg. The notice is annoying but tolerable it’s the sound that it makes every time the notification appears that bugs me. It makes it impossible to quietly send a text. The thing is my settings are set up to only vibrate when sending a msg. has anyone else had this problem?

P.S. I know I can turn off my sounds settings in Notifications Sounds and Settings but I use my alarm and it needs that box checked to work.
