Choosing The Right Measurement Microphone For Accurate Sound Analysis
When it comes to accurately measuring and analyzing sound in Room EQ Wizard (REW), choosing the right measurement microphone is crucial. The microphone you use will directly impact the accuracy and reliability of your measurements.
First and foremost, it is important to understand the difference between measurement microphones and other types of microphones. Measurement microphones are specifically designed to provide a flat frequency response, meaning they capture sound equally across all frequencies. This ensures that the measurements you obtain are not colored or skewed by the microphone itself.
When looking for a measurement microphone, there are a few key factors to consider. One of the most important is the microphone’s frequency response range. It should be capable of capturing sound accurately from the lowest to the highest frequencies you plan to analyze.
Another important factor is the microphone’s sensitivity or signal-to-noise ratio. A high-quality measurement microphone will have a high sensitivity, allowing it to capture low-level sounds without introducing noise or distortion.
Lastly, consider the durability and build quality of the microphone. Ideally, it should be rugged and able to withstand the rigors of frequent measurement sessions.
By investing in a high-quality measurement microphone with a flat frequency response, you can ensure that your sound analysis in Room EQ Wizard is as accurate and reliable as possible.
