Recalibrate audio after sound proofing

Damn! It's a shame, but AFAIK there's no EQ settings in BYD's. I don't know if maybe some DiLink 5 cars may. Maybe tuning the EQ at the source? Like the Spotify EQ or something like that?

When i do the other doors tomorrow i am going to look through the service menues. I remember seeing something about mic calibration so maybe that is it. Or maybe it is just calibration of the build in mics for voice control.

What kind of material did you use? Is it ventilated? I think with things like this, it's especially important to make sure no airlock forms, condensation doesn't occur, and the risk of mold growth is avoided. I have a Seal U DMi myself, but it's still interesting to see what others are struggling with on their models. Good luck!

i have a calibrated mic (umik-1) for my hifi in my living room. So this is very interesting

The measurement-mic is only a small part of the equation. I'm pretty sure you cannot update any DSP directly without a lot of hacking around. Without knowing what electronics/dsp are used its gonna be difficult. Perhaps you can insert some MiniDSP in the audio-chain along the way (either in the analog of digital domain) and apply corrections at that point. Using REW and you Umic you can measure and make corrections where needed.

They use Dirac Live in the ones with the Dynaudio speakers. But i doubt i can access it. Dont know if dirac has some car software that can be used. I think i will research that, could be. But I imagine that it is not accessible.

Yep, most certainly for the mic-array in the ceiling for voice-control over the different quadrants of the car. I don't even think the audio is really "calibrated" anyway. A car is typically considered a very small room. In our HT/Cinema rooms where we employ Dirac or Audyssey (Pro) it is because larger rooms are much more challenging to get things rights Not sure if there if active correction (eg. microphone would measure various noises like wind/tires etc and apply corrections on this) like active noise cancelling or something.

They do use dirac automotive. But it is probably something completely different than dirac live, having to deal with a whole different environment than your living room. So come to think of it you probably cant just remeasure it, there other factors in play. They do actually use ANC to reduce specific frequencies. But I think they do it as a way of saving money on actual sound proofing of the car rather than something to make the car better. And it is definitely not working that well, just got winter tyres on it and they are super loud. And that could be the ANC not configured for that type of noise.

And I agree with the amount of speakers they put in cars these days (eg. 9 -> 25!! yes really) it is also a challenge to get the sound "right" on different listening positions especially with the absence of "masking" engine noises that we have been used to for decades.

Wait. You sound proofed your car? I was thinking I was crazy with the noise the car makes I have a seal u dm-i. The car is quiet but driving long distances when the engine kicks in it's very noisy. Never thought of what you are doing. Well done

Yeah, BYD is really sloppy with that. It all started when i was standing outside my car while the stereo was playing. So much noise getting out. So i took the doorside apart and there was absolutely no sound proofing at all. And then when i got winter tyres on the tire noise really broke through. Whole orhe frequency of noise than the summer tires. So I am trying this, i expect quite the difference since it was not done at all. But it went with vibration dampening and sound dampening rather than sound proofing. When sound proofing you have to go over every surface and make it very tight as it is supposed to keep noise out. With dampening you are adding material to absorb noise instead and that is a lot easier and effective to a surden degree.

what you are doin is commendable. I should do the same. I resort to use earloops on long trips. when the ICE turns up it's really noisy. I know this makes no sense in a new car
