What is the definition of Effectiveness Sounds?

"Sounds of effectiveness sounds like a comedian's dream come true, where every punchline lands perfectly on stage and the audience just can't help but applaud. But let's talk about the darker side - imagine this: 'The new therapy session promised to boost our productivity, so we went in and ended up with a 5-minute lecture on why we're lazy.' That's the kind of effectiveness sounds that could make your therapist jealous."
