[FEAT] I put a perforated metal shell on the board of the microphone array, and the microphone is fixed on the hole, which makes the positioning inaccurate. What could be the reason

In the world of audio engineering, microphone arrays are a crucial component in capturing high-quality sound. However, when a perforated metal shell is placed on the board of the microphone array, and the microphone is fixed on the hole, it can lead to inaccurate positioning. This issue can have significant consequences on the overall sound quality and performance of the microphone array. In this article, we will delve into the possible reasons behind this phenomenon and explore potential solutions.

The motivation behind this issue is to understand the underlying causes of inaccurate positioning when a perforated metal shell is used on the board of the microphone array. This knowledge can be invaluable in designing and optimizing microphone arrays for various applications, such as audio recording, live sound, and acoustic research.

When a perforated metal shell is placed on the board of the microphone array, and the microphone is fixed on the hole, it can lead to inaccurate positioning. This can result in a range of issues, including:

  • Distorted sound: The perforated metal shell can cause sound waves to be reflected and distorted, leading to a loss of clarity and accuracy.
  • Positioning errors: The microphone's position can be affected by the metal shell, resulting in inaccurate sound capture and potentially leading to issues with sound localization and spatial awareness.
  • Interference: The metal shell can also cause electromagnetic interference (EMI) and radio-frequency interference (RFI), which can further compromise the sound quality.

There are several possible reasons why a perforated metal shell on the board of the microphone array can lead to inaccurate positioning:

1. Sound Wave Reflection

When sound waves hit the perforated metal shell, they can be reflected and distorted, leading to a loss of clarity and accuracy. This can result in the microphone capturing sound waves that are not representative of the original sound source.

2. Microphone Positioning

The microphone's position can be affected by the metal shell, resulting in inaccurate sound capture. This can be due to the shell's shape, size, and material properties, which can cause the microphone to be positioned in a way that is not optimal for sound capture.

3. Electromagnetic Interference (EMI)

The metal shell can cause EMI, which can further compromise the sound quality. EMI can be caused by the shell's material properties, such as its conductivity and permeability, which can interact with the microphone's electronics and cause interference.

4. Radio-Frequency Interference (RFI)

The metal shell can also cause RFI, which can further compromise the sound quality. RFI can be caused by the shell's material properties, such as its conductivity and permeability, which can interact with the microphone's electronics and cause interference.

5. Acoustic Coupling

The perforated metal shell can cause acoustic coupling, which can result in the microphone capturing sound waves that are not representative of the original sound source. Acoustic coupling can be caused by the shell's shape, size, and material properties, which can cause the microphone to be positioned in a way that is not optimal for sound capture.

To mitigate the issues caused by a perforated metal shell on the board of the microphone array, the following proposals can be considered:

1. Use a Different Material

Using a different material for the metal shell, such as a non-conductive material, can help to reduce EMI and RFI. This can result in improved sound quality and reduced interference.

2. Optimize the Shell's Shape and Size

Optimizing the shell's shape and size can help to reduce sound wave reflection and improve acoustic coupling. This can result in improved sound quality and reduced positioning errors.

3. Use a Different Microphone Positioning Method

Using a different microphone positioning method, such as a fixed or adjustable mount, can help to improve sound capture and reduce positioning errors. This can result in improved sound quality and reduced interference.

4. Add a Shielding Material

Adding a shielding material, such as a metal mesh or a conductive fabric, can help to reduce EMI and RFI. This can result in improved sound quality and reduced interference.

In conclusion, the use of a perforated metal shell on the board of the microphone array can lead to inaccurate positioning, which can result in a range of issues, including distorted sound, positioning errors, and interference. By understanding the possible reasons behind this phenomenon and exploring potential solutions, we can design and optimize microphone arrays for various applications. The proposals outlined in this article can be used to mitigate the issues caused by a perforated metal shell and improve the overall sound quality and performance of the microphone array.

Based on the analysis and proposals outlined in this article, the following recommendations can be made:

  • Use a different material for the metal shell, such as a non-conductive material, to reduce EMI and RFI.
  • Optimize the shell's shape and size to reduce sound wave reflection and improve acoustic coupling.
  • Use a different microphone positioning method, such as a fixed or adjustable mount, to improve sound capture and reduce positioning errors.
  • Add a shielding material, such as a metal mesh or a conductive fabric, to reduce EMI and RFI.

By following these recommendations, we can improve the sound quality and performance of the microphone array and mitigate the issues caused by a perforated metal shell.
