www.seagate.com Drive Specifications 2.8.1 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 this threshold curve (originated in ISO 389- 7) 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. 2.9 Electromagnetic immunit
