Hit a microphone: causes and elimination

The microphone is a device that perceives the sound and transforming it into electromagnetic oscillations. Due to the large sensitivity, the device can capture third-party signals forming powerful interference. Hissing and interference in the microphone appear on a number of factors that are able to become a serious trouble when transmitting messages by voice or sound recording through the Internet. To remove noises in the microphone, you must first find out why it happens.

Main reasons

Microphones are applied on stage, home recording and when conversations on the Internet. In a certain situation there are third-party noise factors in the device. As a rule, such prerequisites for the occurrence of third-party sounds are considered.

  1. Damaged or low-quality device.
  2. Defects in the connecting cord.
  3. Fancy from the outside.
  4. Invalid configuration.
  5. Unsuitable by.

To get rid of hiss in the device, the microphone itself should be examined before. The damaged device is often the cause of hissing.

Basically in this version appear Powerful distortion when transmitting sound. Sometimes the poor quality device is capable of causeing third-party sound. If the receiver of the sound waves is connected via the cord and the connector, then it makes sense to change the audio channel for its testing. If distortion remains, you can talk about breaking the microphone. For high-quality recording, it is not necessary to use inexpensive devices. They are unreliable and often break.

Methods of elimination

Debugging operating system

Before carrying out any actions on setting up and removing problems, bring our own. For this you follow:

  • Install the drivers on the audio card;
  • if available, install the microphone drivers;
  • to restart a computer.

Keep in mind that Microphone software is not always available – As a rule, they are often not if the microphone is cheap. Expensive professional products have their own drivers. After installation, you can do everything that is indicated below. Do not forget to restart the computer. Without this, some drivers do not start work. This applies to all versions of Windows.

Preventive measure – Install the drivers for the entire equipment that is connected either on your computer. This applies not only to the microphone, but also any other peripheral devices. This will eliminate problems. In addition, it is necessary to ensure that the device and its software are compatible – someone downloads the drivers for the 32-bit version, despite the fact that the 64-bit system themselves – a similar bundle, of course, will not function.

Look at the same way, to be relevant. It is updated infrequently as OS, and yet with the release of the newest version of the driver, for example, for conversation or recording, you can meet with the trouble that your outdated drivers do not allow the device to be operated as before. Consequently – watch the updates and constantly put new versions.

Cord damage

The cord must be visually examined from the beginning to the end to the lips or other damage. There is a working method for checking the integrity of the cord:

  • Connect the PC microphone;
  • Run the Audacity audio file editor (after installing it on a PC) or a different sound recording program;
  • Start moving the microphone cord;
  • Watch for sound recordings.

    If without sounds from the outside on the microphone, you will notice that there are any oscillations and noises in the record, the cord on the line from the microphone to the computer is damaged. When the problem with the cord is necessary, it is necessary or repaired, or change the microphone. The restoration of an inexpensive microphone is inappropriate, Since the cost of repair work is comparable to the acquisition of a new device.

    Preventive measure – carefully contact the cord. You have the opportunity to prolong the life of devices for many years. Cords are out of order so often that this cause of extraneous noise in microphones is located on the 2nd place immediately after problems with the setting of the operating system.

    Try to analyze what is located near the computer. It may be not only your devices, but also the devices of the neighbors through the wall or even a big store below. When detecting a large consumer, try to connect it to another electrical outlet, and better – transfer the microphone itself to another room or computer. Preventive measure in this situation – follow the distance, never connect large devices to the same additional electric cord as your PC.

    External factors

    Often it happens that yesterday noise and distortion was not, and now appeared. What to do? The first thing that comes to the head is the microphone failed. But do not hurry to throw out the device, maybe the problem is in external factors. Powerful factor that strongly affects the microphone – other devices.

    For example, if the refrigerator is either a different large and powerful device connected to the same electrical outlet as your laptop or PC, then the risk that the microphone will begin to make noise, very high.

    Problems due to third-party software

    Often the problem is not because of third-party software as the fault of the software you use to work with the microphone. For example, if you wish to contact someone on Skype. In separate programs You need to manually make microphone settings. In certain utilities, there is also a specialized liquidation regime of problems that will allow you to open the cause of difficulties, and in some cases it will help to figure out how to cancel them. If you are worth a program, “Improving” computer work, it is also able to affect the operation of the microphone. It is worth disconnecting or deleted at all and see whether the situation has become better.

    Microphone output

    In the case of a complete failure of the device, you need to identify the problem. It can be both in the microphone and in the computer. For this you need to make such events.

    • Connect another microphone to PC – to experience whether there will be a hiss that does not hear the voices.
    • Connect a microphone to a computer in which there is definitely no interference – This will allow you to find out if the microphone will function correctly.

    After you have done you will understand what is the problem. If the hiss is available on 2 different computers, then the defect in the microphone. When the hiss only on your computer, and on the other it is not, then the problem is lurking in your computer. In addition, it can be in the settings of the operating system or the absence of drivers. How to resolve this task, said above.

    When the microphone does not function either hit on 2 devices, you can perform this test on the 3rd device, while it can be a cell phone.

    If the result is the same, then with a probability of 99% the problem in the microphone. Need to decide: repair it either change to a new.


    There are a number of minor “surprises”, which is faced by an unprepared user during the operation of the microphone.

    1. Instead of the sound of hissing, it may be due to the program, it may have an amplifier or incorrect setting. As a consequence, using Skype, TeamSpeak and other means to communicate, you need to experience the work of the device by a mansion from them. For example, in Skype by default there is auto-tuning, it must be removed.
    2. As mentioned above, it is necessary to record the cord, often low-quality options are simply transmitted or a piece of coating is shifted. You should visually check the cord, and more reliably change to another and try.
    3. Possible reason lies in the nests, they probably dug, clogged or faulty. In addition, you should not use the front connectors, the quality of the signal in them is usually worse. It must be stopped the plug to another connector – the problem may abide.
    4. Apply specialized noise suppression programs. They can improve sound quality, only sometimes with volume loss. Common and common applications need to highlight: Adaptive Noise Reduction, Hard Limiter.

    Noises when operating a microphone after said actions should abyss. Otherwise you can talk about the breakdown of the microphone itself, then it needs to be repaired or acquired a new.
