In addition to these answers, I'd say that most of the time it is unlikely that the stomping will go away completely. As a result, in the future you must try to get a top floor apartment. As a last, I recommend getting a bluetooth speaker with bass, but not turned up high. Listen to"Rumble Works - Ambient Low Frequency Noisescape for Ten Hours" on youtube with bass about 50%. It is good at masking the stomps. Stomps are low frequency sounds so you need low frequency noise to effectively mask it. — Jarvis 12 secs ago

Brown noise + gray noise with bass speakers is a great way to mask the stomping. It's been very helpful. And it doesn't have to be very loud to the point your neighbor can hear it. The physics of the acoustics allow it to work effectively at even low volume. I've become a near sound expert over the past 2 weeks because I am also dealing with a new tenant. I rather try to solve the issue using principles of sound waves before going any further. — Jarvis 2 mins ago

It's unlikely that you can get a carpenter to modify any apartment complex. That's likely something not allowed in your lease. But you can install sound insulation foam panels that can easily be taken down once your lease expires. Most complexes allow something like that. You may need assistance to help you put them on the ceiling depending on your comfort. — Jarvis 17 secs ago

Knowing what they know is important. Their entire training is about keeping you in conversation, because the moment the conversation stops, their chances drops to 0. It's not necessarily being unscrupulous, but that's part of the training. The more you talk, the more invested you become, and you eventually cave to give so that you don't "feel bad" about taking up their time. It is a well known sales tactic. This is why sales people will give you stuff, talk with you, give you sample, let you borrow the device for a day or two, etc, etc etc. They're just trying to take up your time. — Nelson 1 min ago
