10.2.8 Advanced - Acoustic Management Configuration

Note:

Automatic acoustic management (AAM) is a method for reducing acoustic emanations in AT Attachment

(ATA) mass storage devices, such as ATA hard disk drives and ATAPI optical disc drives. AAM is an

optional feature set for ATA/ATAPI devices; when a device supports AAM, the acoustic management

parameters are adjustable through a software or firmware user interface.

The ATA/ATAPI sub-command for setting the level of AAM operation is an 8-bit value from 0 to 255.

Most modern drives ship with the vendor-defined value of 0x00 in the acoustic management setting.

This often translates to the max-performance value of 254 stated in the standard. Values between 128

and 254 (0x80 - 0xFE) enable the feature and select most-quiet to most-performance settings along that

range. Though hard drive manufacturers may support the whole range of values, the settings are

allowed to be banded so many values could provide the same acoustic performance.
