Ultrasound tracking

Some background https://www.bleepingcomputer.com/news/s … tor-users/

I think ultrasound (or the way it's used by advertisers) is very worrying. It can be used for tracking people. Even if you're using VPN or Tor.

However there are some easy things to do to make your everyday computing at least a little safer.  For Google Chrome there's an extension to block ultrasounds from websites. http://ubeacsec.org/

Disable flash from your browser.

Disable microphone from your computers when you're not using them.

There are also ways to remove microphone from mobile phones, but it's much more complicated so I'm not going to go through that in here.

By disabling microphones, you ensure (at least to some extent) that your devices are not receiving ultrasounds. An interesting idea would be to write a sound firewall for PC.
