A device placed over a microphone that reduces the effect of wind noise on the microphone. There are two main types of windshields, modular systems and integral slip-on systems. A modular system (often called a blimp or zeppelin) consists of a flexible grey plastic netting tube (thus the name) with a screening material and a suspension system for the microphone (e.g. Rycote Modular Windshield). A furry synthetic fur cover, often called a windjammer, can be placed over the zeppelin for additional wind noise attenuation. In documentary and ENG applications one-piece slip on windshields consisting of a cellular foam base surrounded by synthetic fur are quite popular (e.g. Rycote Softie Windshield). The foam wind screen that comes with most microphones is only good to prevent wind noise due to movement of the microphone, outdoor shooting requires a windshield. Furry slip on systems or windjammers are sometimes called a dead cat. Some folks refer to a blimps windjammer attachment as a Wookie since they are typically larger than dead cats.
