Perhaps Martin meant that nobody has been able to measure BM motion below 60 dB with dysfunctional outer hair cells? But that wouldn't be a proof there is no motion. In fact, it would be difficult to understand why there wouldn't be any motion below 60 dB, however small.

For many years now, the measurement sensitivity for BM excursions has been well below 1 nanometer. Now, if BM motion is < 1 nm at 60 dB, how big then can it be at 0 dB?

Please do the maths, and then come back. You can be sure that all readers of this thread will tremendously enjoy that figure.
