may make you less critical of Neumann’s mark-up, but it’s worth it.


Two of these tiny mikes attached to a pair of headphones make a great binaural
recording set-up. Mount one at the focus of a parabolic reflector (a satellite dish
or kid’s snow-saucer) for a hyper-directional mike for wildlife sound recording.
These mikes are cheap enough to embed in musical instruments -- they’re great
inside accordions and melodicas and in mutes for trumpets and trombones.


Even the least expensive of electret microphone elements has a surprisingly
extended bass response -- often extending down to 20Hz or so. They are very
susceptible to wind noise and breath pops, and you may need to roll off the bass
to avoid overloading your recorder input under certain circumstances. But this
also makes them excellent for picking up subsonic pressure waves, such as those
produced by opening and closing doors, wind gusts and some weather changes -



  • in this case roll off everything above 50Hz and the remainder is your weather.
