Types of directional microphones
The parabolic microphones are very directional microphones, as they allow us to pick up sound several meters from the source, are microphones that are often used to record natural sounds, or as spy microphones, but to get quality sounds at a distance, we will have to scratch our pocket.
In addition to knowing what is a directional microphone, you must identify the main features to consider when buying a directional microphone or boom microphone, which are as follows:
This feature is what differentiates a true directional microphone, of those that seem it. It is common to find mixed patterns in addition to Supercardioid, Hypercardioid, and Lobar in this type of microphones as: Supercardioid / Lobar or Line + Gradient, the optimal pattern would be the Lobar, but we must investigate each brand to find out which has the axis of more closed pickup, as this feature greatly influences the budget.
In English it is literally called Dead Cat, and it looks like it when we carry it in our microphone suitcase, this singular object protects us from the strongest winds, achieving incredible results, you only have to put it as a coat of your Zeppelin and you will stop listening to the wind, even if it blows hard.

We have made the decision to get a hearing aid to improve our hearing, but where do we start? We recommend you to use our hearing aid recommender that, depending on your preferences and daily needs, will recommend you different hearing aids and you will be able to compare their prices and characteristics before going to a quality hearing center.
It is important to know the product before buying it. Audiotek, hearing centers located in the province of Barcelona, place special emphasis on knowing how to differentiate between sound amplifiers and hearing aids.
Hearing aids can operate all their components thanks to rechargeable batteries or batteries. In the case of batteries, they are usually zinc batteries with oxygen components. They usually have an average life of between 3 and 14 days, depending on the power required to supply the user’s hearing deficit.
In the case of some hearing aids, one of the parts most valued by users is the earmold. The earmold is made to fit the user’s ear and helps to fix the hearing aid so that it does not move. In addition, it also has other functions:
However, the omnidirectional microphone becomes more directional when exposed to high frequencies. If the device is picking up sound sources from the entire angle of coverage, sounds emitted at high frequencies will be privileged from the front and rear of the capsule.
Do not confuse the training standard with the transduction mechanism of the microphone. The second category refers to the sensitivity of the device membrane. We have the dynamic microphone, the condenser and the ribbon microphone. The traditional ribbon microphone has a bidirectional pickup standard (Figure 8), but nowadays there are already ribbons with variable standards. Dynamic and condenser mics vary between different standards, many of them omnidirectional.
Also known as boominess, this is very evident in directional microphones. The closer the sound source is to the capsule, the higher the bass frequencies. Extreme focus can even produce distortion in the recorded audio.

Knowing how to choose the best microphone for you means knowing exactly what you need it for. Microphones, as we all know, vary in many of their characteristics, and it is your personal obligation to maximize those advantages for your own benefit. A live vocalist’s microphone is not the same as a microphone used for PC activities. Both cases can be excellent microphones and can be unidirectional, each oriented for different conditions. In this post we will detail the best unidirectional microphones, and where we can use them.
Unidirectional microphones are those that capture the sound frontally, obviating or minimizing the side sounds and sounds that are behind the microphone. This feature has many application advantages, which we will see in the course of our article.
