In video production, it should be stated that mixing and recording in an art. It involves achieving the right balance between attaining precise and direct speech. Also, there should not be too much background sound. The Speech-to-noise ratio is an important factor to consider when recording video content.
What is Speech-to-Nose Ratio?
Speech-to-Noise Ratio is often referred to as SNR. It is nothing but the evaluation of the level of background noise relative to speech in an audio stream. This ratio plays a crucial role in how well people can understand the content discussed in your videos that are recorded in noisy atmospheres.
You can follow different techniques to raise the speech-to-noise ratio in video production. Here are a few methods you can follow:
Ways To Reduce Background Noise In Videos
Reduce Distance
Bringing down the distance between the microphone and the subject is the most effective technique to enhance the speech-to-noise ratio. When you capture videos in noisy settings, you can use Lavalier Microphones. The microphones from this brand are known to record videos and give the best outcomes. Many reputed camera shops can have microphones from this brand. Indeed, you can buy online as well.
Use Directional Microphones
You can opt for super-cardioid pattern microphones. Also, signals not in the off-axis or pickup audio are relatively less sensitive to super-cardioid mics. The same rule applies to shotgun and cardioid mics. With the best quality mics, you can cut out background noise right at the recording stage itself. You need not have to search for a video editing tool that can help get rid of background noise.
Use A Sturdy Mic Stand
Using a sturdy microphone stand is yet another technique you can follow during the video production process. When the mic stands in a constant state, you can ask the subject to stand in a particular position close to the mic. By following this technique, background noises can be reduced to a great extent.
Use Pop Filters
For blocking out plosives, you can use pop filters when recording videos. A pop filter is nothing but a thin membrane of fabric. It will help block the popping sounds that some consonants like plosives create. When you are close to the microphone, you can apparently hear these gusts of air in your videos. To avoid this, you can clip a pop filter to your mic stand. It will let air hover right between your mic and the subject.
Use Dynamic Mics in Noisy Atmospheres
You might have heard about condenser and dynamic microphones used in video production. Both of them have their benefits. In comparison with an average condenser mic, an average dynamic mic is less sensitive. It means that dynamic mics gain a better edge in handling noisy atmospheres. With these mics, you can enhance your speech-to-noise ratio.
In addition to the tips mentioned above, you can record your videos as much as possible in a quiet room. Also, using clean electrical sources and ensuring the proper plugging of plugs can help enhance the speech-to-noise ratio.
