It really depends on the program.
GPA is very important but most programs look at your entire application holistically. So if you are concerned about a lower GPA then make other sections of your application stand out. For example, try to get some hands-on experience as a hearing screener or at an audiology clinic as some type of assistant. I had a lot of hands-on experience and I was very successful in the application process. Work on your GRE score if it is below average!
There is a lot of data on each school's admission numbers on ASHA's website. Target schools that have a higher admission rate, received low numbers of applications, or accepted applicants with lower GPAs. I have linked it below for reference. https://find.asha.org/ed#q=audiology&sort=relevancy&f:@degreeprogram=[Entry-Level Clinical Doctoral Degree in Audiology]
Good Luck!
