Samsung has announced 80GB and 160GB flavours of its new 3.5” SpinPoint S166 Series of ultra silent and high-speed hard disk drives. The S166 Series has a spindle speed of 7,200RPM, provides an 8MB buffer, features the SATA 3.0Gbps interface (PATA interface also available) and includes Native Command Queuing. The new SpinPoint S Series of hard drives offer upgraded versions of Samsung’s proprietary SilentSeek and NoiseGuard technologies. Benchmarking results presented by Samsung show competing hard drives generate on average 2.8 bel (1 bel = 10 decibels) in idle mode and 3.2 bel in seek mode, while Samsung’s S166 series generate just 2.4 bel and 2.75 bel respectively. Samsung claims the 15% noise-level reduction is “significant”.
“Samsung is constantly pushing the technology envelope with the introduction of new and innovative products that meet the computing needs of today’s most demanding customers and operating environments. This latest technology development by Samsung in the new SpinPoint S166 Series makes our high-end, award-winning hard drive products attractive to a wider audience by even further reducing acoustic noise and improving disk data transfer speed,” states TJ Lee, vice president of sales & marketing at Samsung Electronics’ Storage System Division.

Based upon the decibals, it is a 15% reduction. And decibals correspond to the noise. The ACTUAL noise rather than the numbers is maybe more than 15%.
At least this is the explaination Samsung would give
The way it works out in the real world is that for every 3db of difference in measured sound level, there's 100% perceived difference in loudness. So 24db sound is twice as loud as 21db sound.
In the case of Samsung drives above we are talking about 0.47db difference, which in fact is close enough to the quoted 15% noise-reduction.
Agreed, after adding water cooling to my setup there was still a lot of case noise/vibration which was solely due to the HDD's. I fixed it in the end, but it was very noticeable at the time.
