Yes, a familiar alarm can become easier to ignore. Rotate among a few tested sounds and, more importantly, change what the sound makes you do.
The sound has learned the morning too
You know the pattern: at first the new tone makes your heart jump. A month later it is playing inside a dream. The sound may still be loud enough; it has simply joined a familiar pattern where ringing is followed by a thumb and more sleep.
Changing the tone can restore attention for a while. It won't fix the habit if every new sound still ends with the phone beside your pillow.
Give the signal a new ending
Choose two or three clear tones and test them in the room. Put the phone where it isn't muffled, then finish a task somewhere useful. The alarm should begin movement rather than carry the whole wake-up alone.
Avoid an endless search for more shocking noise. Very loud sound disturbs others and may be uncomfortable. If you sleep through everything, look at sleep and health rather than continuing the volume contest.
Common questions
How often should I change the sound?
Change it when you clearly notice habituation, not on a fixed calendar. Keep a few sounds you know are audible.
Is a random sound better?
Novelty may help, but predictability can also reduce anxiety. The action after the sound usually matters more.
