PowerDeWise Microphone: How to solve a smartphone buzzing sound problem

If you are experiencing a buzzing sound when you are using the microphone with your smartphone, relax, take a deep breath, then please note the following points: 

  1. Restart Your Device

An overloaded RAM or a slow and tired device could be giving out a high-pitched buzz. Restarting it will reset every function and start everything afresh. If what's causing the sound is an aberration in the system, it should stop after restarting.  

  1. Bad Connections

Ensure that the microphone properly plugged into the microphone jack.  A loose connection between the microphone and the audio device, like an amp, speaker or computer, could cause a buzz or hum. Try tightening the connections to ensure that they fit securely. A secure, tight connection will not cause interference and you can achieve this by pushing every male end into the female until you hear a “click” sound. If there’s no proper contact between the mic and the device, the connection will not work properly.  

  1. Microphone Distance and Positioning

Holding the microphone too close to the sound source while using it may cause buzzing or distortion. Hold the microphone slightly away from your mouth while using it to reduce any buzzing or humming noises.  Place the subject where you want him positioned in the camera frame. Position the mic about six to eight inches from the subject’s mouth. A spot on the person’s chest usually works best.

  1. Electrical Disruption

Sometimes, other electrical devices near the audio system can cause a buzzing sound because the microphone picks up the electrical output. Keep the microphone clear from other electrical devices and move the microphone wire away from other wires to reduce the buzzing noise. Avoid charging your device while using it with the microphone. 

  1. Dirty Microphone jack

If the plug of the connected external microphone is dirty it could also produce a buzzing or crackling sound.  So, try using a cotton bud or cotton swab to carefully clean the mic/headphone jack of your device. Wipe the microphone connector with an alcohol swab to have all the dirt and grease away and test
