iPhone 15 Buzzer Too Quiet

Ever since I’ve gotten my iPhone 15 Pro, I’ve been missing so many calls. I always leave my phone on silent because I’d rather hear it buzz than play a sound. With my older phones, it buzzed loud enough when on hard surfaces for me to hear it even when I was across the room. But now, I miss phone calls when I’m right next to my phone because the buzzer is so quiet. Is there a way to increase the intensity of the buzzer so I can still hear my phone ring when I’m on silent??
