Singing noise
 

Singing noise
I just notice a new noise and was wondering if anyone else has heard it as well, at 70 mph there is a singing noise and I'm hoping it is but it sounds like it's coming from the hpfp. It only does it under light throttle. When you let off or give wot it goes away. I can just barely hear crickets at idle and really is not bad. It gets louder at 80 and higher. If it's not the hpfp I might really be sol.

what kind of singing? Celine Dion type or more like R Kelly?

wut?

"Singing noise?" What is a "singing noise?" Can you describe it better than that? It could be that your music is too loud.

I was thinking more of meatloaf, or Michael McDonald?

Op, please reply.

The noise is a high pitch whine or squeak but is not crickets, like a harmonic singing noise from a bearing or a pump. I would appreciate serious replies only. Thank you.

A high pitch harmonic singing noise, gotcha. Would you say from a female or male vocal?

Resonance from the door mirrors or something underhood.

I just remembered that my truck did something similar, I wouldn't worry about it.

Was messing with it on the freeway last night, it's not so much that mine 'goes away' under more throttle, it's covered up by the increased noise and throttle-off results in a decreased speed such that the noise doesn't occur anymore.

I think you're fine.

Thanks for the reply but I really think it's coming from the hpfp, I can control the noise with light throttle on and off at speeds 67mph and up. Just wondering if anyone else has heard it, I'm taking it into the dealer next but but I'm taking it on a trip this weekend. If it is the pump I should not have any issues since I have not heard of any of them failing yet just the noise issues, if it's not the pump I don't want to cause any progressive damage.

Someone a while back said they got resonance from their rear differential. Dealer diagnosis: replace the rear differential. Resonance gone.

But that was a different kind of singing. Probably barotone.

I've always noticed this at highway speeds. Always assumed it was the HPFP.

Is it at a specific speed, and does it go away under heavier throttle or deceleration?

Did you ever change your differential oil?

I used to have this "problem" with my Kaaz diff in my S13. It was a combination of the oil used + improperly set backlash.

Eagerly anticipating the new single coming out from your car. When is the expected release date?

I'm waiting to see who the FR-S relieves itself on first.

Singing noise, huh? Enter one of the singing shows, and let's see how good it is haha

There is just a bunch of trolls responding so might as well close it

I hear the same thing, a whine. I was worried on my way back from formula d.

I hear the noise in mine as well. Approx. 72 mph it makes a harmonic frequency that resonates. changes with throttle. No idea what causes it but I've heard it for about a month now. I always thought "Whine" described it. Heard it could be the diff before, but never thought anything of it. just got used to it since my g/f Toyota does the same thing.

Probably the rear diff. Sometimes at certain speeds and light throttle loads the sound can be induced.

Unless it gets worse really quickly, I wouldn't worry too much.

I've noticed something in my car as well. Usually at any cruising speed not under load or acceleration. But I feel like i hear it towards the front, around the transmission area.

Solution: turn my music back on and stop listening for noises.

You guys can all start a band together!

Perhaps a sound clip would have produced more useful replies.

To those who have this "singing" noise, do you have a trd intake as well? I've had this noise for a while now and it gets annoying sometimes. It's a high-pitched noise that appears under light throttle at highway speeds even on cruise control.

Mine does it as well although I feel like it's more toward the trans... Oh well, power train warranty.

I uploaded a video in hopes someone can identify the cause and a fix.

I let off the throttle here and there to turn it off and on.

Does anyone have this whining and not have a trd intake??

What about a non-stock tran/rear diff fluid?

I'm wondering if it might be the hpfp. It's pretty noticeable once you hear it, comes on around 70mph light throttle.

This noise is aggravating but not an issue. I know mine has done it since day one and I now have 37k miles and it's still doing it. I chalked it up to the car not liking 70mph so I run 72. Easiest fix EVER!!! You can hear it at 35mph as well if you listen close, leads me to believe it would blow your eardrums at 140mph :)

i can't seem to hear anything where in the video am i suppose to listen closely?

You might need to raise the volume a bit you can hear it throughout the entire video. It turns off at times when I let off the throttle.

HPFP? If you've got High-Performance Fragmentation Projectiles coming by, close enough to hear them sing; I suggest taking a different route.

I doubt it's the pump. The noise would show up at the same RPM no matter how fast you were going. The sound is speed related. I can't figure out what it is either.
