Installing Microphone Windscreens
Windscreens should be installed on SMM-U1 microphones for long-term
deployments in all areas susceptible to heavy wind driven rain. This could result in
permanent damage to the microphone element due to water penetration. The
risk is greater when deployed with the ultrasonic horn attachment. For short-term
deployments with predictions of less severe weather and in dry climates, you can
avoid using windscreens.
The windscreens will attenuate ultrasound by only a few dB when dry. However,
they will block most ultrasound when soaked with water, until they dry. Drying
time can vary significantly based on temperature, humidity and wind.
Secure the windscreens for the SMM-U1 microphone with the included C-clip.
Make sure there is an air gap between the windscreen and the microphone as
shown below. (Do not pull the windscreen down tightly).
For the SMX-Horn directional attachment, secure the large windscreen with the
included zip-tie as shown below. Exact positioning is not important.
