Re: Surf noise spectrum

[lamprophis1963]

I agree.  I filtered out the intermediate bird sounds and
listened to just the lower and higher frequency sounds by
themselves and I think a lot of the sound between 2700 and 4000
is a distant chorus of insects.

Hi Peter,
I think that band is primarily insects not surf - a dense
background chorus of tree crickets, cicadas or something.

This recording was made about 4km inland at Wilsons Promontory in
Victoria, Australia. There was a strong swell and there's a lot
of surf noise in the background as I expected, but I didn't
expect to see it concentrated between 2700 and 4000Hz on the
spectrogram. Is that usual? Why so high?
