How to use Pink Noise?
For an objective test of the speaker’s response, you will need a metering system. This consists of a device that can measure the spectral output of the loudspeaker in real time and a source of pink noise that can be played back through the loudspeakers.
We have created an iOS app with these tools built in so you can quickly test and calibrate your LYD speakers using your iPhone, iPad or iPod touch. In the Apple App Store, search for “Dynaudio Meter” to locate and download this free app.
You can connect the device directly to the speakers using a conventional headphone to RCA adapter. Play the pink noise from the Dynaudio Meter and adjust the level for a reasonable playback volume. If you wish to play pink noise from your computer workstation, a WAV file containing pink noise is available at the bottom of this page.
Play the pink noise through one speaker at a time at a reasonable level (~80-85dBA) and place the iPhone or iPad at the listening position. Change the Sound Balance filter to see how the response changes the response curve in the RTA. Pink noise is a balanced level of noise across the entire spectrum. In the RTA display, the reading should be as level and even as possible.
If you notice excessive levels in the low frequencies, try setting the Sound Balance filter to Bright (B) and check the results. If the spectrum analyzer shows a greater degree of high frequencies, set the tilt filter to dark (D) and check the results.
Once you have the tilt filter set for the flattest response curve in the RTA, return to your reference material to see how it sounds. Through this process of objective tests with the RTA and subjective listening tests with your ears, you will arrive at the best setting for your Dynaudio loudspeakers.
