Google Calendar event reminder sound is too short and I can't hear it

One of the main Google Calendar's functions is to remind people their events, with a scheduled sound alarm. The problem is that this sound, I know how to change it , only lasts for 1 second, so I don't hear it. Instead, when they call me, the sound lasts for very long until they hang up the phone, so I realize I'm being called. I would like if the alarm sound lasted longer, how to do it? By the way, I have the same problem with Google Keep reminders. I imagine some people like short sounds because they don't want to get disturbed, and they probably get reminded when they check their phones and see the notification. I want to know if it's possible to make it work like I specified, a longer loud sound like a call.
