Recesses ceiling lights caused acoustic problem

I am trying to insatall 8-10 LED recessed light on my downstairs living room. Direct above this room are bedrooms. there is no isolation between these two floors, a neighbor who has similar floorplane told me she feels weird acoustic since she added 10 recessed ceiling lights - suddenly she can hear whisper from the rooms in different floors. I try to avoid her nightmares from adding these recessed ceiling lights, thinking about to add some insulation or sound absorbed materials around each lighting house I put in. Is it a good idea? What materials do you recommend?
FYI, this is the light I am going to use

Do you rent? If you rent you should not be doing any electric work in your apartment.

I'd be amazed if those tiny lights will caused any sound issues.
Most likely there is no insulation in that ceiling now, if there was no issue before it's not going to happen after the lights are installed.

I would not recommend using the lights from Costco. I would only get them from a lighting/electrical supplier or home improvement store. Lights like the ones from another store will likely be of poor quality.

If you install any insulation around the can they will need to be IC rated.

The Costco lights are rated for insulation use. They don't look very forgiving in hole size. It's hard to install 4" recessed lights in a 4" hole. The Costco ones require a little over 3-3/4" inches. Since they are the LED type..... the front of the fixture is probably sealed and won't allow any noise thru it.
