Can you hear that a rear wheel is not true?

On a recent 30 mph descent, the ticking of the rear hub was not even but had a steady pulsing pitch change with each revolution. Sure enough, the rear wheel was no longer true. Is it common to 'hear' that your rear wheel is not true?

If you are referring to the singing sound that the spokes make from the road vibrations, then yes, it can vary with spoke tension.

You'll probably find that the wheel sounds the same on descents after truing.

30 mph? I say yes depending on how out of true it is, how hard of hearing you are, and wind speed and direction. Definitely while braking.

How often do you make descents at that speed? Could it have been that the wheel is actually slightly out of balance rather than out or true? Which presumably would always be present unlike the out of true wheel. Or, perhaps was it the untrue wheel slightly rubbing on the brake pads?

I could feel the rim hit one of the brake pads, when I broke 1 spoke on the rear, (out of 48)

..... at my typical touring speed which is way less than 30 mph.

You can hear or feel a flat spot on the rim. Same with a bulging tire.

I agree with the guy who said the sound will still be there after truing.

An out of round tire may give a similar sound.
The hub/bearings would be slightly loaded/unloaded every revolution.

If it's a 36 hole rim, you need to check your spokes. I had the same deal recently. Spoke was broken & I didn't even know it till I started checking tension on each one individually. Spoke was broken at the hole in hub & appeared OK. I think I rode bike about three or four times before I figured it out.
