How do microphone Windshields work? 

How do microphone A windbreak is intended to prevent linear air movements that are generated by wind or other disturbing noises.  The windshield works by deflecting and redirecting the movement of the wind, but also by the structure of the mic windshield . If the windjammer is uneven in structure and has a large surface area where many small turbulences can form, it will block the wind. A fur windshield can provide even more protection against unwanted noise, since air movements are converted into mechanical energy by the fine hair of the fur.

How good can a windshield protect against background noise?

Different types of windshields provide different levels of protection. In addition, the manufacturer is also decisive when it comes to the quality of the wind protections.

However, it is possible to reduce wind noise by up to 70dB with extensive equipment without the desired audio frequency being damaged.

What are the disadvantages of a microphone windshield ?

The windshield can cause a slight loss of loudness in higher frequencies. But the original levels can any time be reproduced in their original dynamical range. It can also happen that the fine dynamics of the signal will be deteriorated. The windshield makes the microphone more conspicuous, larger, and also bulkier. So be careful and step a little closer to save audio dynamics.

Depending on the windshield , the microphone may only be able to be operated to a limited extent. It can also happen that settings or mute buttons are hardly accessible. A microphone windshield is not part of the standard equipment of a microphone and must be purchased separately.

Besides a microphone windshield, what other options are there to improve the sound quality?

​There are other ways to protect a microphone from wind noise, e.g., with a sock or piece of fabric as a substitute windshield.

However, these methods are not nearly as effective as using a real microphone windshield.

It might happen that the audio loses high frequencies, or a permanent rustling can be heard in the recording. 

Do you only need a windshield if you are recording outdoors?

No, microphone windshield can also be helpful indoors. Wind protection is necessary wherever strong air movements hit the microphone. Even when speaking directly into the microphone, breathing noises or simply a loud pronunciation can lead to popping, smacking and crackling noises.

In addition, a pop protection, another type of wind protection, can also be used for singing or voice recordings.

Finally, the microphone itself can also cause wind, when swiveling around on a boom pole or when passing a hand-held microphone. So always keep one eye on the mic and the other one on your levels. 

What must be considered when using a microphone windshield?

The wind force must be correctly estimated before recording, so check weather forecasts for your location for that day. It is better to estimate the wind force higher than lower.

It should be ensured that a suitable windshield is used, which is tailored for the microphone type, so that it fits properly.

Furthermore, it is particularly important to ensure correct installation and a good fit so that the windshield does not produce any accidental noise. You should also pay attention to all other types of background noise when recording outdoors.
