Is the TV Wall mounted or table mounted? Changing to location can be helpful. Also you can get speakers that can put the audio on a table beside the listener. I use Home Pods connected to my TV. Bluetooth connected enables you to move them anywhere for TV or Music Audio from your phone.
Mass-loaded vinyl and acoustic panels can fit behind a wall-mounted TV.
There are also Audio settings on the TV Menu that you can adjust to help. Some settings remove the bass specifically to adjust for these kinds of things.
Kitchen noises are a bit different. Those are sharper sounds like glasses, dishware, pots pans, dishwasher. It also depends on the flooring there as these are high traffic.
A rubber underlayment can be helpful, but that is done at time of build. Rugs on the floors can help foot traffic noises. It also is a large echo space typically. Wall hangings of more photo’s or Felting can deaden the echo dramatically.
There is a field of sound and acoustic engineering that fits in this umbrella. I recall building a call center years ago and everything from the floor, ceiling tiles, workspace walls can make a huge difference. The upcharge on acoustic rated items is tremendous but does wonders.
I grew up in a larger household and my bedroom was next to the kitchen. I worked 3rd shift in college and would come home for sleep prior to classes just as my 4 other siblings were getting breakfast before school. I learned to sleep with a pillow wrapped over my head. To this very day I will wrap a pillow over my head to block any noise or morning light if I need to sleep longer. It’s like being a turtle.
