How do you produce echo from residential Complex adjoining a main road to deter indiscriminate horning by vehicle drivers?

To produce echo as a deterrent to indiscriminate honking near a residential complex, you could install sound-reflective materials, such as barriers or walls, designed to bounce sound waves back. Additionally, incorporating sound-absorbing features in combination with strategic landscaping can enhance the effect. This setup may confuse drivers by amplifying the sound of their own honking, encouraging them to reduce noise levels. However, consider local noise regulations and community feedback before implementing such measures.
