This is a very short script that I have been asked to created by MrChristian Luminos who told me that there is no such script available either on marketplace or the wiki. The script just toggles a sound on and off when an avatar touches the primitive the script is in.

• Drop the script in a primitive of your choice.
• Edit the script and modify the SOUND parameter at the top of the script to reference a sound UUID or a sound name if the sound-clip is in the same primitive this script will be placed in. The script triggers one of my sneezing recording from Wizardry and Steamworks.

string SOUND = "9fb1f482-5edf-1544-98c4-b8f86ea9ea26";
integer o = -1;
 
default
{
 
    touch_start(integer total_number)
    {
        if(o = ~o) {
            llStopSound();
            return;
        }
        llLoopSound(SOUND, 1);
    }
}

The sound is played using llLoopSound and at volume 1 (maximum). However, you can replace those with say:

llPlaySound(SOUND, .5);

If you want the sound to be played just once and at half volume.
