I am assuming that with a power top, the ANC is easily switched off/on, as the electronics, if even by a simple switch, will know the status of the top. With a mechanical and fully removable top, I doubt such status will be readily available for the ANC. The mics may help shut it off at a certain decibel level, but that remains to be seen.My Mustang convertible has ANC, but it shuts down when the top is lowered. The volume and sound curve is also modified.
Some owners don't like the Mustang ANC. No off switch. But they did find that if they disabled all of the microphones scattered around the cabin...it didn't activate!
Totally passive, you do nothing, and it's active all of the time.So do you activate the noise cancellation system by a button or ut is already activated when you turn on the music or radio or it is already activated when youbswitch on the car whithout turning on sound system??
You can see the mics right behind the driver and passenger seats on the sport bar.I'm assuming they just use the mics to determine the various top status. While I'm guessing, I bet they have a background noise floor and ceiling since they aren't going to blast the speakers with the top down which would still fail to cancel the wind noise. There's all sorts of audio processing magic they could do.
The only way to effectively test the ANC is to do a side X side test with 2 JLs (one with and one without obviously) with a decibel meter and in similar various conditions.Does that mean there's no way to test its effectiveness by switching it on and off? I would be interested in knowing how effective it is.
