Well, it was a neat surprise to me when I discovered that a newly purchased - not Seagate which I almost always used - drive has all the acoustic stuff in place.
ATA device, with non-removable media Model Number: Hitachi HUA721050KLA330 Firmware Revision: GK6OA70M Recommended acoustic management value: 128, current value: 128 * Automatic Acoustic Management feature set ...
And it's indeed more quiet when seeking if acoustic management value is set to 128, and quite more load when set to 255. Speed decreases a bit (I didn't do any measurements), but not much.
Western Digital drives also has acoustic management in place. At least some of them. But I never heard of this stuff present for Seagate drives - my guess is that those are in a "good" compromise between speed and loudness already :)
