There are many types of microphones, depending on the application and purpose, but they all have almost the same parameters. One of them is the sensitivity of the microphone. Sometimes it is too high and creates an echo or "phonite" effect. For this, the sensitivity is specially degraded, both by software and hardware methods.
Instructions
Step 1
If the connection goes through a computer, run a special mixer program. It can be called differently in different operating systems, and it can be launched in different ways. Find the function of the microphone sensitivity regulator in the program. Use it to reduce the sensitivity to the required level.
Step 2
If you are connecting a microphone to a tape recorder, find a manual or automatic recording level switch on it. Use it to select a manual way to control the recording level. Reduce it with the appropriate regulator. It is impossible to do this by ear, so watch the indicator readings (almost all tape recorders, in which manual control of the recording level is provided, have it).
Step 3
When using a dynamic microphone, which is used in karaoke, but is not suitable for computers, connect through an attenuator, also made of a variable resistor. The microphone resistance should be ten times less than the value of this resistor. Connect the common cable of the cord that goes to the computer and the microphone to the left contact of the resistor, connect the microphone output to the right, and the sound card input to the middle.
Step 4
If the intermediary device is designed to work with a dynamic microphone, then it is possible to use such a microphone, the sensitivity of which selectively changes depending on the location of the sound source, and which is capable of acting on the microphone membrane on one side more strongly than on the other, or is generally located on removal and has the same effect on the membrane from both sides. In this case, sounds are practically not perceived by the microphone.
Step 5
The sensitivity can be reduced mechanically. To do this, wrap the microphone with a cloth (vary the number of layers according to the sound).
