Array microphone: How it works, advantages and areas of application

An array microphone consists of several microphone capsules that are placed in a geometric arrangement and together precisely capture audio signals. These microphones use digital signal processing to accurately detect sound sources, reduce background noise and improve speech quality. They are used in various applications, from everyday devices such as laptops to professional audio devices.

As an experienced provider of comprehensive media technology services and a specialist in the field of audio technology, ComPeri is your expert partner for array microphones. We will provide you with comprehensive information on the functionality, areas of application and the numerous advantages of these modern microphone solutions.


How an array microphone works

An array microphone consists of several microphone capsules that are connected to each other – sometimes up to a hundred pieces. These capsules work together to capture sound signals, which are then processed by a digital signal processor (DSP).

This process makes it possible to specifically control the recording direction of the microphone array. With the help of digital technology (matrixing), the system can acoustically scan certain areas of the room and focus flexibly on them. For example, the array can be automatically aligned to a person who is speaking, even if they are moving. Alternatively, the array can be set so that it has a fixed, freely selectable recording characteristic. This means it can either record sounds from all directions (360 degrees) or focus on a specific direction - depending on the requirements of the situation.


Application areas of array microphones

Array microphones can be found in both everyday and professional environments:

  • A common example is the Array Microphone Laptop, which is used in modern laptops for voice recording during video conferences or speech recognition software.
  • Another example is the dual array microphone in the notebook, which optimizes voice quality by using multiple microphones and reduces noisy background noise.

Array microphones are also indispensable in audio recording studios and in conference room technology. Thanks to their special arrangement and ability to pick up multiple sound sources simultaneously, they can be used flexibly in conference rooms, auditoriums or meeting rooms without compromising the aesthetics or functionality of the room. Array microphones also minimize the risk of interference between different microphones as they offer an integrated solution for sound pick-up.

 

Array microphones: the technical advantages

An array microphone offers numerous advantages that make it an ideal choice for a wide range of applications:

  • Precise voice pickup for clear communication
  • Effective suppression of ambient noise
  • Improved voice intelligibility in laptops and notebooks, ideal for video conferencing and online meetings
  • Possibility to target sound sources from specific directions capture


How are array microphones used in audio technology?

In lecture situations, microphones such as desk microphones, handheld microphones or clip-on and headset microphones are often used. These microphones offer reliable audio recording, but have one common feature: they are visible. Although many of these microphones are designed to be aesthetically pleasing, there are situations where the visibility of a microphone can be disruptive - especially in large conferences with multiple participants.


If several speakers need to be recorded in a room, the use of multiple desk microphones can quickly lead to visual overload. The room appears cluttered and unclear due to the many visible microphones.


In such scenarios, array microphones offer an excellent alternative. They enable high-performance yet unobtrusive miking, as they do not need to be installed visibly. Array microphones can be inconspicuously integrated into the ceiling or into conference tables, depending on the room size and acoustics.
