Anyone between East 9th street and East 10th street BTW 1st Ave and Ave A (back of the bulidings) know the source of this madness inducing wailing? (no nyu or woo hoo jokes please - sadly, this is a 'quality of life' related noise request) <br />311 has been of no help so far so I'd like to track down the source myself with the help of fellow Grievers.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5694390946037511355.post-48858422761038063942013-06-07T15:34:05.115-04:002013-06-07T15:34:05.115-04:00My smartphone has an application which acts like a...My smartphone has an application which acts like a spectrum analyzer. It will sample sounds using its microphone, do and FFT and plot frequency and amplitude. Using this I am able to pinpoint a high pitch noise in my office to a particular power supply which I'm now getting rid of.richardwhttps://www.blogger.com/profile/03451701312758121411noreply@blogger.comtag:blogger.com,1999:blog-5694390946037511355.post-25864654682910431722013-04-25T07:52:40.866-04:002013-04-25T07:52:40.866-04:00Happening right now.
