Hi, Does anyone have any ideas on how to augment the sound from the step-on scream mats? I use those to activate my dropping spiders and a few other things. However they don't work very well even when the sound box is side by side with the spider. There's probably too much background noise in my haunted nouse so that their noise can't compete well. It takes a really sharp sound like a loud clap or scream to get the spiders to activate.
