Hi all
Recently I was out in the Nationalpark Thy in Northern Denmark, to record a=
mbiences just after sunset, when I came across an extremely weak humming-so=
und. Barely audible without the recorder gain at max. It turned out to be h=
undreds of mosquitoes inside a small forest. I started recording, and then =
when I made the announcement into the mic, I noticed the mosquito-hum raisi=
ng in pitch for a short moment. I made different experiments, and it seemed=
they only reacted to my voice each time, and not any other sounds I made.
Has anyone come across that phenomenon? Is it a known fact that mosquitos c=
an "hear" humans, and distinguish them from other sounds? I've never heard =
of that.
I put up the recording on SoundCloud, but it probably requires some good he=
adphones to hear the phenomenon:

(I speak to the mosquitoes in danish, but don't bother. I'm not saying anyt=
hing very intelligent anyway. After all, they are only mosquitoes...)
