COMBATING GENTRIFICATION WITH SOUND INSULLATION

When considering ways to combat gentrification, we often focus on global, political, and financial policies that can encourage equitable urban investments.
However!
Is it possible to address gentrification through a range of "mini incentives"? For instance, could sound insulation help prevent gentrification?
To explore this concept further, we would like to share a personal story.

One of us resides in an apartment on the second floor of a multifamily row house. A few years ago, the third floor was rented to a young family with a small child as part of a social housing program. Although this family was very kind and friendly, they were extremely noisy, even past 11:30 pm. The initial reaction is often to call the landlord and file a complaint immediately.
Such an action would have been an act of gentrification. A person with educational capital, like us, complaining to the landlord about a family renting a social housing unit would essentially be gentrification.
Being aware of this issue, we attempted to address the noise problem directly with the neighbors. Unfortunately, this approach was unsuccessful. Our neighbors believed we were exaggerating the problem and were overly sensitive to noise. However, for us, the main issue was the noise from the TV and the kitchen, often continuing until 3 am.
While we personally believe that living in multifamily buildings requires a lot of common sense, we also recognize that people have the right to live their lives according to their own rhythms and cultures. In other words, although we were disturbed by the constant noise late at night, we understood that these individuals had the right to be active during those hours.

The primary issue was the lack of adequate sound insulation between floors.

After numerous discussions, we agreed to contact the landlord to request sound insulation installation. Although the landlord was willing to assist, he never pursued proper sound insulation. Instead, he suggested minor alternative measures, attempting to address the issue with minimal effort and cost. The result was a thin layer of carpet under the existing wooden floor, which did not resolve the problem.

Further discussions and disagreements ensued as the issue persisted.

A few months later, we noticed a moving truck in front of our house. The family on the third floor was moving out. We felt both happy and sad. We never discovered why they decided to leave, but we knew that proper sound insulation could have prevented it.
The final conclusion is this: Landlords and property owners should be encouraged through laws and subsidies to install proper sound insulation. While thermal insulation requires permits, sound insulation remains marginalized. We strongly believe that installing proper sound insulation can reduce gentrification to some extent and enhance the quality of life for neighbors by fostering a sense of community.
