This sound is from Alertbrain's Zedge Ringtones (Safe for everyone) (LOUDEST NSFW OR SFW 👂🏽👂🏽⚠️ OR SOFTEST NSFW OR SFW👂🏽👂🏽)

Those are all my sound effects that I use them as Ringtones, A big library that I will have them as Notification sound effects ranging from what I have got. So Feel free to enjoy those sound effects and also use these sounds as ringtones if you want for notifications.
