It's called "Deaf of Deaf." I know what I am talking about because I used to be part of the "Deaf of Deaf" crowd. They reject other Deaf people based on their genetic history. If they come from hearing parents, they don't "belong" in the group. That is a form of audism. Grummer likes to call it deafism, however it just weird to give a reverse-discrimination its own name when it's already defined by Humparies.
Some people reject other deaf people based on the fact they could talk on the cellphone. Audism. Some Deaf say that you're not "deaf" enough if you can still hear certain things. Audism. One of the members on the forum blasted another user and called her a "hearing-oppressor," unfortunately the thread got removed this morning, so I cannot link to it at the moment. Hell, I know of deaf people full out reject those that have Auditory Processing Disorder.I know of a Deaf couple in Winnipeg that gave up their hearing baby for adoption, but kept all their genetically deaf babies. Audism.

No, they are not different. They are just words to describe the concept. Ageism, racism, sexism, classism and reverse-discrimination applies to all of them:
Ageism - Discrimination based on age (young, old, middle)
Sexism - Discrimination based on gender (male, female, heterosexual, homosexual, transsexual and transgender)
Logocism/Linguacism - Discrimination based on language
Classism - Discrimination based on class (lower, middle, upper middle, upper class)
Racism - Discrimination based on races
Audism - Discrimination based on hearing (profoundly deaf, severely deaf, moderately deaf, mildly deaf or "hard-of-hearing," and fully-hearing)
Ableism - Discrimination based on disability or lack of disability
All of these have examples of reverse-discriminations. So yes, audism is comparable to racism. The only different is the that the root words are different with the same suffix. Same concept.
Anytime a society become stratified, it is a sign that discrimination is occurring. And the Deaf-World
is stratified.
