CD Read Errors--Rare?

In the latest issue of The Absolute Sound on p. 131, Robert Harley claims that errors in a CD player's bit stream are rare. His argument is that an error in the first bit in the sample would throw the amplitude off by half, resulting in "a very loud click." Since we don't hear loud clicks during playback, there must not be many first bit errors, which means there must not be many error at all.

Here is my question: Since the sample is only 1/44,100 of a second long, and speaker diaphrams do not react instantaneously to signal changes, would the "click" end up being inaudible?
It depends. There are a lot of effects going on. Nerve bundles in the ear fire slowly - less than 4 Khz. So one individual error may or may not be audible depending on when it occurred. Of course many errors would audible.
I don't remember if it was the latest TAS, but I recall Robert Hartley talking about potential CD read errors, and stating that they should be rare. I think the reasoning was much deeper than that we would hear clicks if there were read errors. There was a discussion of the error correction encoding and he detailed how many consecutive bits would have to be misread and/or unable to be read, to generate a genuine read error.

Reading off a CD for playback should be basically error free. Reading off a hard drive or out of RAM would be literally effor free. It just seems that the handling of digital files in the digital domain is a solved problem.
The error correcting code used for CD data is not a band-aid for the occasional read error. It is an essential part of the data storage and retrieval process. It permits the system to be operated at a much higher bandwidth than the hardware could manage if read errors could not be allowed to occur. Read errors are frequent, but a group of errors extensive enough to get through the error correcting code is rare.
What Robert was describing was a single bit error in the most significant bit (MSB) position. There could be single bit errors in the least significant bit (LSB) position and you would never know it. Of course, single bit errors, whether MSB or LSB will be corrected by the error correcting code. In the early days of CD players, they had Error LEDs that lit up when there were bit errors that could not be corrected.

I wonder why modern players or DACS don't have such LEDs?
Hartley's claim was that even though the sample is only 1/44100 of a second long, if the error occurred at a point where there was a major shift in the sound (my words) it would be translated as a click. The click would be audible. If that is the case, the question would be ... how often do your hear clicks on CD playback? I can't remember hearing even one anytime in recent memory.

It wasn't the single bit error he was concerned about if I remember correctly. It was the two bit error, which you can definetely hear, even on LPs.
Same argument applies to 2-bit errors that applies to 1-bit errors -- it depends on the bit positions as to whether they'll be audible. MSB positions having a much larger impact than LSB position. I'm pretty sure that the ECC can correct 2-bit errors as well. I believe that when the number of errors in a sample surpasses a threshold the output is muted.
