Playing low frequency noise to disrupt hard-drives: denial of service for CCTVs, data-centers, and other computing environments

The farthest successfully performed attack was at the distance of 71 cm (92.8 dBA) for the 1 TB HDD at 9.1 kHz frequency, and 44 cm (102.6 dbA) for the 4 TB HDD at 8.5 kHz.

9.1kHz and 8.5 kHz? I thought it said low frequency. For audible sound, this pretty high.
