An older couple in their mid 80s to 90s lost their home in the Tubbs fire and did not feel like choosing new tiles for their new house in the next 2 years. They decided with their son to move in with him and his wife and re-arrange the master bedrooms. It was a typical set for 3 bedrooms 2 baths so I created 2 master suites. Her concern was noise, since the elderly couple spent a lot of time watching TV in their bedrooms at a high volume. We created a sound insulation wall, and she reported that she cannot hear their TV.
