How to disable specific sounds in some scenarios?

Hello everyone, this is my first post here and I hope I'm following all guidelines regarding how to ask questions on the forum.

I'm a ML Researcher and currently using ViZDoom as a platform for experiments with intelligent agents. I have this scenario called Health Gathering Supreme and I want to disable the sound that the player constantly emits because it is taking damage. I need this because I set other Things on the map to play sounds, and the task here is to find these objects by using the sound. However, since the player is always taking damage the noises get mixed up making the task of finding the correct sources harder than it should be.

 I'm pretty new to Doom Editing, but I managed to place the new objects that I want on the map and also managed to make them emit different sounds. So as a player, I can hear them but also listen to myself "in pain" all the time.

On this topic, someone tried disabling another kind of sound, and the suggestion was to replace the "misc/secret" sound in the SNDINFO file with just an empty set of ". I tried the same, but I don't know exactly what is the equivalent of "misc/secret" that I have to disable.

Any suggestions or guidance will be much appreciated. 

Thanks :D
