If you have an iPhone, there are a few ways to change the notification sound. This includes adjusting the sound preferences in your settings, or by using a third-party app. To adjust the notification sound on your iPhone, open the Settings app and select General. In the General section, select Sound & Notification. Under Sound, select which type of notification you want to hear when your phone wakes up or goes to sleep. You can also choose to have all notifications play at once or individual notifications play for a set amount of time after being received. If you want to change the notification sound on an individual basis, open the Notification Center and select one of your notifications. Then under Sound, select how loud you want that notification to be played.
