Did anyone's "chime" sounds change recently?

[threeonone]

Today I noticed my chime sounds in the vehicle are different. For when you start up the vehicle as well as the proximity sensor warning chimes have a different sound. I assume it's from an over the air software update, but I can't find any info on it in the app.

I liked the old sounds better. Odd.

Covid Ear?...... too soon?

This happened to me awhile ago. The sensor sound sounded different for a few days, then went back to normal. No idea why.

I think it may have been making the same sound, just playing from a different location or different speaker or something. No idea what was going on.

I have experienced this exact thing in a couple other Fords, but it's been a while and I don't remember the details.

Happens once a week in my 2020 Raptor. I think it happened once in my Bronco so far. 1400 miles. I think it has to do with the audio boot up in SYNC. I can't diagnose under what conditions it happens, Totally random.

Is the sound coming from your speakers or the instrument panel

I think when it sounded weird for me for a few days it came from the instrument panel or nearby. Normally it seems to be spatially appropriate to which sensor is alarming, via the normal sound system?

I think it’s a software glitch with the sound system not turning on. When I adjustment my rear speakers to full range in forscan it make my speaker BLAST the tone. So I changed it to go to the instrument panel and it’s a similar sound but different. I prefer it

Do you have a guide for the full range speakers?

Do you have a guide for the full range speakers?

There are a few threads on it. Search forscan full range rear

This happens when the specific barometric pressure goes below 20 CFMC. It so happens that the pitch of Ford's programmed chimes will be altered by the lower barometric pressure ever so slightly, but enough to hear the difference. This effect is influenced by the Williamson Cationic Curve, which is well known by Air Force and Navy pilots, who in WWII experienced missing instrument ques when audible warning chimes sounded different at varying altitudes . . . due to the changing barometric pressure. Therefore if your chimes sound different for a period of time, it is only because you were experiencing a temporary change in barometric pressure. If you were to use a Williamson Cationic Curve conversion chart ($20 on Amazon) and the Williamson App on your phone, you will be able to see the degree by which you need to change your barometric pressure to hear the chime in its intended tone again. In most cases you can do that by rolling up all the windows and blasting the AC on full for 5 minutes, followed by immediately changing to full heat for about a minute. The sudden change in temperature will balance the barometric pressure and the chime will sound normal again.

But it's possible this is just a bunch of malarkey I made up because I'm bored tonight.

Just when you thought you were smart this guy shows up! Lol. I knew the speed of sound “down here” was 760mph and at FL 410 it is 660mph. But you just took it to another level of wisdom.

If this isn't really a thing, it should be. Yeah, I could Google it and see if you're pulling our leg with clever BS. Nah, I don't care. It sounds brilliant, so it is. .

Now if you could offer some help with my deafening tinnitus. Or help me tune it ....

I like it

I've noticed it will switch between the speakers and the cluster, I haven't quite figured out the conditions that cause it to switch.
