A question about Eternal Doom's sound effects

[StarSpun5000]

I think a good majority of us know about Eternal Doom. The exploration and puzzle focused Wad released in 1997. You may also be aware of the many sound replacements used in the Wad, two of which will be the topic of discussion. I am referring to a pair of zombie wake up sounds, one that sounds like a low laugh and the other that is the sound of someone saying "He's over there, I see him." One thing I've always wondered about these sounds is where they came from. I've always thought of the possibility that these could actually be the voices of some of the people who worked on the Wad. Does anyone have any info as to where these two sounds came from?

I believe they were recorded by @rfnagel.

If I recall correctly, they are from Laura Beyer's Doom.

Huh you're right, I assumed it had been Rich Nagel since he did the "Welcome to Eternal Doom" greeting sound.
