Noise Level Rating
How loud is a location due to environmental noise
I’m a pen pal to a Southern California appraiser, who posted this message about Soundscore to a forum I read.
Here’s a site I found that provides some very useful information as to how loud a particular site or location might be. Type in an address and, voila! Their system comes back with a rating as to how much noise the site has from vehicle traffic, airline traffic, and local sources. It’s on a scale of 50 to 100, with 50 being very loud and 100 being very quiet.
This is a ‘free’ site to use.
I decided to test the site using my address, and 3 other addresses of distant properties I know of. In all cases, the relative noise levels reported by this ‘HowLoud’ web site appear to be realistic (based on their number ratings) for those property locations.
The site may have practical applications in terms of making a location adjustment – depending on comp locations. Appraisers will have to decide if it makes sense to do so, and then figure out a weighting procedure/process to give it validity. But if done this way, and documented in the report, it will have far more credibility than the typical PFA adjustments often made.
As an example, my address shows a “84” rating, or ‘Calm.’ My place is about ¼ mile from a freeway and an active railroad line close to the freeway. I then picked a different address of a home due east of my place immediately adjacent to the freeway and nearer the railroad. That property shows “62”, or ‘Busy’ which is correct due to the increased noise levels in that location.
This site can’t discern highly detailed differences if the properties are relatively close together. However, if a property is on a known active arterial-type road and others are not, it might. You will have to test it in your community to know for sure.
Try it out and see what you think.
