MP3 file of mosquito sounds of flying

Just listening makes me feel uncomfortable and itchy. But this sound, according to an experiment by a researcher in the UK, when preparing female and male mosquitoes, they respond with each other with this feather sound so that the speed and height of the sound are aligned.

An MP3 file of mosquito-jumping sound that may be used for something is from the following.

You can listen by clicking the button labeled "MP3" on the page. Indeed it will be a similar tone with a single point as a boundary that was different halfway through.

Or, if you let this sound at a loud volume it is only harassing.
