In outdoor-recording, high wind and rain are generally a problem as this causes unwanted noise in the microphone signal. In order to prevent noise, the microphones can be protected from the weather by using windjammers, windscreens, etc. However, the effectiveness of these products varies significantly and full specifications characterizing maximum wind speed permitted, wind attenuation, spectral damping, influence by rain etc., are seldom given. In this paper an overview of the problems involved in outdoor recording is presented. It also presents measurement methods that provide more informative and useful specifications.
