The financial value of a residence or business located in tall buildings is often thought to be determined by its views. Scenic vistas usually fetch bigger rents. Noise pollution, on the other hand, decreases the value of a residence or office. Listening to sounds over 65+ decibels for long periods makes people anxious, edgy nervous. Even white noise–like wind or large fans cuts down on worker’s or tenants satisfaction. It also impedes the ability to clearly hear and enjoy soft discussions or music. For these reasons DDIS measures and communicates noises at various altitudes. We record the existing sound at elevation and combine it with the proposed viewshed you would get from a specific balcony, amenity deck or rooftop garden. Architects and sound engineers can use our data to locate problem areas and mitigate them with techniques, such as triple-paned glass and noise walls. DDIS simulations use visual and audio data to help advise potential tenants about the potential ‘feel’ of a new unit before purchasing.
