AT&T Samsung Galaxy S4 - Repeat Notification during conversation

[Dwinegar]

So I am a fairly new android user and I have a Galaxy S4 upgrading from an Iphone. My one and only problem is the notifications for text messages. On my Iphone I would receive a notification and when I would pull the conversation up all other texts during the period I had the text app and conversation on my screen I would hear a nice little beep not the full notification sound. On my Galaxy it seems to want to play the notification sound on every text even when I have the conversation open. Is there a way to stop it from giving me the notifications when the app is active on screen or am I stuck dealing with it?
