INTRODUCTION
Background
The sound is due to periodic fluctuations in air pressure around the atmospheric pressure in the form of local and regional meetings tenuous. Meetings because the pressure is greater than atmospheric pressure and the tenuous because the pressure is lower than atmospheric pressure. Fluctuations are transmitted through the medium of air and into the ear and the eardrum vibrates, so that voice.
The voice we hear coming from various sources. Source of the sound that is the distribution centers known as the voice of the sound. The voice that came out of the sound source can be recorded and stored for different purposes, eg for research purposes.
This requires an instrument that can be used to record sound. One of the tools required in the sound recording is a sensor that can change the sound into electrical signals, and then processed using a computer in the form of digital signals. Sensor or tranducher used to convert sounds into the microphone electric signal.
Most microphones in general have a frequency response range between 20 Hz to 20 KHz, but the usage is usually adjusted to used. For a variety of different purposes, microphone built into several types. Each type of microphone has a characteristic and different responses.
We have several types of commonly used microphone Condenser microphone namely, dynamic microphone, carbon microphone and the piezoelectric microphone. Condensor microphone is a microphone that works on the principle of equal chip capacitors, dynamic microphone works with the principle of electromagnetic induction, c Arbon microphone works with the principle of change resistance piezoelektric microphone while working on the principle of pressure changes. Each type of microphone has a sensitivity varying depending of the sensor sensitivity and the quality of the compiled materials.
Microphone has a characteristic or particular patterns of response or capture sound waves coming. This pattern is associated with the frequency of the sound issued by the sound source. This pattern will then be referred to as directivitas or polar pattern microphone. If the voice coming out of low-frequency sound source, then the microphone will have a uniform response at each point the same distance from its center. Conversely, the higher the frequency of the sound source, the microphone has a more focused response on a particular point.
In a variety of purposes, especially for audio recording, microphone laying position is very influential to the quality and characteristics of the resulting sound. Sound recordings produced by a good microphone will sound even less than the maximum if placed arbitrarily. Eg microphone placed opposite to the direction of the sound, the microphone captured the sound will seem less maximal. Others as appropriate if the microphone is placed facing the direction of the sound.
To get the position of laying the proper microphone, so that the quality and character produced maximum sound as necessary, then the first note the characteristics of the microphone direktivitas pattern that will be used. This research was conducted to answer whether it was true that the frequency of the sound issued by the source of the noise impact on direktivitas pattern microphone
