Now, I think a professional way to do this would be using an audio analyzer tool like ones offered by Audio Precision. Shop quality True Audio TrueRTA Audio Spectrum Analyzer Software at wholesale price, with real time product reviews. Another way would be to use a data acquisition tool to do this automatically. You can test as many different frequencies as you would like, 15, 30, 60.Ī DIY way to do this would be to measure RMS voltage with a o-scope and record the values at each frequency. Ideally you would want to test all the speakers frequency response to see what you have. Then you can plot these in X-Y to see what the frequency response looks like.
Each time you play a different frequency sine wave, you will record a different RMS voltage and then you can build a simple table with frequency vs. Then you need to measure the RMS voltage across the resistor while you play sine waves at different frequencies into the resistor. You need to hold the load constant so it doesn't vary with output frequency like a speaker does. You just need to disconnect a speaker and insert a resistive load in its place (8 ohm non-inductive resistor would do the trick). From my experience, Ford does apply equalization to the electrical output on the Sync system. I can share my results with you and the procedure I used. As the acoustic measuring tools, REW (Room EQ Wizard) and TrueRTA (RealTime Audio Spectrum Analyzer) are compared on the frequency response ofthe SPL (Sound Pressure Level) and the 2nd Harmonic Distortion(2nd HD)and the 3rd Harmonic Distortion (3rd HD). I had a great time doing it & learned a lot. I have done this type of testing on my 2011 Ford Mustang GT with Sync. That's the reason I'd just as soon pay for the one-time measurement by someone already equipped for the job if it isn't cost prohibitive.Ĭlick to expand.This is an awesome question. Could be solved with purchase of an external soundcard/pre-in but it starts to add-up and I don't see any other future use for the setup. Somewhat complicated by my Dell laptop's single-jack mic/headphone connector (why I went with the USB UMIK-1 calibrated mic) with no spec found for its acceptable input voltage range to enter into the voltage divider calc. It'll take a lot more research to come up with the DIY tools to measure as described in the linked ERIN H post. Ford touts it is 'tuned for the application' so it's reasonable to expect the built-in response curve would differ between the Escape and the Focus (the replacement PN's are different for the 'same' component). If you built a piece of audio gear and want to test for frequency response and THD, it's *almost* perfect.Click to expand.Yeah, I've not been able to find any OEM specs or test data on the specific HU I have, used on certain Focus & Escape models for '13-'15 (not the unit mentioned by DDfusion). Not perfect, but with some simple considerations, you can get really professional measurements at little cost this way. Also watch out for ground loops, it's easy to show mains hum down a ways if you don't keep that in mind, especially testing unbalanced signals. I/O is generally balanced, although unbalanced operation is easy. Also the input impedance is great for line level signals but probably not for high impedance work, so that's something to keep in mind. Also some traps: These have minimal input protection and can handle +4dBu signal levels but not much more. 4) Room EQ Wizard- REW is free room acoustics analysis software for measuring and analysing room and loudspeaker responses.
TrueRTA runs under Windows Vista, 7, 8 and 10.

Even a basic $200 interface will outperform most scopes in this regard. TrueRTA turns your PC into a powerful audio test system normally seen only in better audio research and design laboratories. It's not about the bandwidth, its about the dynamic range and linearity. Obviously bandwidth gets questionable below 20hz, but usually can do down to 5hz depending on the interface. You can see harmonics way down in the noise if needed. Most of these soundcards show a noise floor below 120dB FS, I usually set the graph to show 140 dB range.

Also includes a great signal generator (pink noise, white noise, sine wave, lock sine to FFT, sweeps, etc). This program does in-depth realtime FFT analysis and can quickly output frequency response plots, and will tell you THD, THD+N, etc.
There is a free program over on the Home Theater Shack forum called "REW: Room EQ Wizard" (requires forum membership). You will get a very linear 24 bit dynamic range as standard, and some have sample rates as high as 192k.

I would recommend checking out any pro/semi pro music supply (guitar center, sweetwater, etc.) and getting a 96k sample rate or better audio interface.
