Windproof is an accessory for a microphone, which is necessary in the work of any sound engineer. Without it, it is not necessary for any recording studios, nor on street “living” performances of performers, nor on direct broadcasts of various kinds, where singers, musicians, speakers can act.
Main appointment windproof – Filtering of sound interference. This inexpensive addition to the microphone largely ensures the purity of the sound, even if the equipment is very expensive. Without windproofs, it is impossible to get a clean living sound in the open air or make professional sound recording of high-quality sound.
Sensitive microphone diaphragm exposed to sharp wind gusts. Air flows hit the solid edges of the input channels of an unprotected operating microphone and create a swirl. There is a characteristic noise, whistling, “Will”, the sound is distorted. With strong wind, if the microphone operates for a long time, damage to the equipment.
Protective covers “inhibit” air in front of the microphone and “take a blow to ourselves”.
The microphone windproof is necessary when working in the premises. In professional studios during recording, the sharp breath of the performers during the pronunciation of some “explosive” consonants, primarily “B” and “P”, creates a sound blow to the diaphragm of the device. The quality of the recording is reduced, the negative effect is interferes with the listeners. The use of protection avoids such troubles.
It is worth noting that the details of expensive studio equipment must be protected not only from air. When working in a voice from the artist, an insignificant amount of the smallest drops of saliva involuntarily splashes, the composition of which is not harmless to highly sensitive elements of the microphone. With this problem help to cope with simple devices, which are called pop filters. They are subtle nylon overlays on the microphone, they are used in the premises From the wind do not save, but the sound quality increases and extends the service life of the equipment.
During the production of windproof cases for microphones, sound-permeable materials are used, allowing filtering outsiders and save beneficial sound signals without frequency distortion and without changing voice. Most often it is foam and artificial fur.
This is the most common universal version. Acoustic pores in the material provide original sound, reduce the noise level and do not allow frequency distortion. The nozzle from the foam rubber is ideal for premises, but when writing on the street does not cope with strong wind gusts. The disadvantage is considered Relative short-life, Since the foam sponge with time begins to crumble.
Natural fur does not fit, since he has a low-speed leather basis capable of drowning sound signals. Used naval artificial fur with a loose basis. Static electricity of artificial fur does not allow vilns to join each other and retains them “fluffiness”. Fur windproof effectively protects the microphone from strong air flows in the open space. I must say that When a beautiful fur case is put on the microphone, the accessory acquires additional aesthetics.
Sometimes in studios, protection from fine metal mesh is used, but such an accessory protects mainly from mechanical damage, and for high-quality conservation of speech and vocal characteristics on the microphone, the covers of foam rubber or fur are put on the microphone.
Features of use
To get the maximum effect from windproof, We must consider the specifications of a specific model, where it will be used (indoors or on the street), which will be recorded (speech, vocals, music). Accessory needed almost on all types of microphones: dynamic, studio, petrolery, vocal, microphones, guns and others. The case must be selected proportionally the diameter of the microphone, to fit tightly to the device and close the membrane, otherwise there will be no effective protection against extraneous sounds. Cover walls should not exceed 1.5 – 2 cm in thickness.
Windproof designed for street conditions, Ideally should have a water-repellent impregnation with a special composition. The operation of the microphone with such a cover will not worsen, even if during the performance suddenly it will rain or wet snow. In addition to direct destination, windproofs on microphones are often used for promotional purposes – it is convenient to depict all sorts of logos of goods, companies, hits and T. NS. This advertisement will simultaneously see a considerable audience. Microphone windproofs are needed not only by professional sound engineers. In modern life, amateur records became one of the favorite entertainment. Record concerts, corporate parties, family celebrations, activities in nature, while there are a lot of attention and the quality of the image, and the purity of the sound. The windshield of microphones in this process belongs not the last role.
