Acoustics
Acoustical design
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 psycho-acoustical
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 the table below.

in Dell Enterprise Products.
PowerEdge acoustical specifications
For more information on acoustical specifications, see ENG0019663. (See the category definitions.)
Dell typically categorizes servers in five categories of acoustically acceptable usage:
● Category 1: Table-top in Office Environment
● Category 2: Floor-standing in Office Environment
● Category 3: General Use Space
● Category 4: Attended Data Center
● Category 5: Unattended Data Center
Category 1: Floor-standing in Office Environment
When Dell determines that a specific Enterprise product is to be used on a table-top in office environment, for example, on
a desk around a seated user’s head height, then the acoustical specification of the following table applies. Small, light-weight
towers are examples of these types of products.
