I agree. For several years I have been looking on and off for a layman way to locate a source of a sound, but haven't found anything.
A solution like this could resolve many of the lingering "hum" cases. Often they are only heard by a few people, and those in charge of environmental control don't tend to take it seriously because "they don't hear it", or because they or the higher-ups are hiding something.
Acoustic consultants are extremely expensive, may require many hours if the sound is only apparent during random hours, and even then may come up with nothing.
An app that would at least be able to give a good estimate of the direction from where a sound is coming would be extremely helpful.
