First, extract the included cheer.resource and cheer.assets files to your steamapps\NASCAR Heat Evolution\NASCARHeatEvolution_Data folder.
Next, run the included mod package (Crowd Noise Mute) EXE to update the resources.resource file to look for the audio clip for the crowd cheer in the newly created cheer.assets file, which includes a muted crowd noise WAV file. I've run several test races and haven't heard the annoying crowd noise again so I am releasing this for those who are also bothered by the crowd noise.
If the feedback from this is good, and nobody encounters issues this will open up the ability to edit even more sounds in the game!
