2.10Acoustics emissions

Drive emission of sound is measured consistent with the ECMA-74 and its referenced standards. Testing is con- ducted at room temperature (approximately 25 degrees C). Emission levels are reported as the total A-weighted sound power levels for, steady state, idle and active (seek) modes of operations.

[1]During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels.

Test for Prominent Discrete Tones (PDTs)

Seagate follows the ECMA-74 standards for measurement and identification of PDTs. An exception to this process is the use of the absolute threshold of hearing. Seagate uses the lower limit for the threshold curve* to discern tone audibility and to compensate for the inaudible components of sound prior to computation of tone ratios according to Annex D of the ECMA-74 standards.

* Defined as the median curve given by ISO 389-7 (Tf curve) minus 10dB at all frequencies.
