5 PowerEdge 14th generation (14G) acoustical performance and dependencies | Document ID | version (optional)
Overview
Dell EMC PowerEdge delivers sound quality and smooth transient response in addition to sound power levels
and sound pressure levels oriented to deployment environments. Sound quality describes how disturbing or
pleasing a person finds a sound, as a function of a variety of psychoacoustical metrics and thresholds. Tone
prominence is one such metric. Transient response refers to how sound changes with time. Sound power
level, sound pressure level, and loudness refer to amplitude of sound. A reference for comparison to sound
pressure levels and loudness for familiar noise sources is given in Table 1. A more extensive description of
Dell EMC PowerEdge acoustical design and metrics is available in the white paper, “Dell Enterprise
Acoustics”
