Provided you are a radical approximately the sound condition of your vehivle's stereo action, you Testament wish to manipulate a real-time analyser (RTA). It can scanner Everyone Closeness of bebop across the spectrum from 20 Hertz (Hz) to 20,000 Hz and peruse peaks and valleys in the Closeness scale. Once you be acquainted where the peaks and valleys are, you can generate adjustments to eliminate them, ensuring a smooth transition between frequencies.
Instructions
Preparations
1. Shop for a Disc that plays pink boisterousness. Pink noise is all frequencies of the spectrum generated at the identical common. It sounds passion static when you play it.
2.8. Play the CD with pink noise through your sound system. Set the CD player to repeat the track.

10. Take the meter and stand outside the car when you run the test.
11. Put the RTA in the test mode. A graph will appear on its display. This graph is a visual reading of the sound of your system from 20 Hz to 20,000 Hz. The dots beside the bars that define the frequency display a sound level of either 1/10 or 3 dB. This helps you determine how much more sound level one frequency has over another. The RTA will print out a graph.
12. Use the graph to adjust your equalizer to eliminate the peaks and valleys and achieve a smooth transition from frequency to frequency.
