Automatic acoustic management

Automatic Acoustic Management, AAM short, is a technique that allows an adjustment of the noise level of a computer hard disk.

Overview

The read-write head mechanism is either faster and thus increase or - positioned quieter and slower - by implication. AAM order is limited to the access noise, to have no effect on the idle acoustics. The adjustment is made by special software in the hard disk itself, and persists until it is changed permanently. Typically, you can already achieve significant noise reduction with little loss in performance.

AAM was introduced with the ATA -6 standard as an optional feature in 2002. Some current models do without for cost reasons or legal reasons it. Certain of AAM relevant techniques are protected by patents of the company Convolve (U.S. 6,314,473 ) and Seagate (U.S. 6,704,159 ).

AAM was in the ATA ACS-2 standard ( T13/2015-D ) Revision 4a explains the December 2010 obsolete.
