I get your point dear, you're kinda talking about self discipline but then I don't think the sound is what attracts people to keep gambling, well the instance you used sounds true but don't you think that as people then to grow older they deviate from such mentality? Or do you still do that whenever you hear the sound of the ice-cream? I bet you must have grown past that by now and even learn to control your emotions from giving in to the sound, after there's no sound from sports betting but many folks still get addicted to it, why because they're not disciplined enough to overcome addiction, once someone acknowledge the consequences of being addicted, then discipline themselves towards it, not even sounds from the slot games can make the person deviate.
