Example implementations relate to generating a performance index of an electrical device. An example implementation includes determining an acoustical contour of a soundscape within a computing enclosure for housing the electrical device. A performance response of the electrical device when subjected to the soundscape within the computing enclosure may be determined. Specifically, a soundscape may be generated within a test chamber that replicates the acoustical contour of the soundscape within the computing enclosure. A performance index of the electrical device may be generated upon being subjected to the generated soundscape.

Replicating contours of soundscapes within computing enclosures

In some examples herein relate to a system for testing an axial fan, the system comprising a V-shaped seat to allocate the axial fan, the V-shaped seat comprises a first surface established on a top side of the V-shaped set, a second surface established on the top side of the V-shaped set. An intersection between the first surface and the second surface forms a V-shaped surface of 90 degrees to allocate the axial fan on the V-shaped seat and the V-shaped surface has sticky and resilient properties to fix the axial fan on the V-shaped surface.

Devices for testing axial fans

A vibration attenuation method comprising identifying a hard drive disposed on an electronic device and, based on the identity of the hard drive, attenuating an output of at least one operation of the electronic device.

Vibration identification and attenuation system and method

Embodiments of the present invention relate to a system and method for noise suppression. Specifically, embodiments of the present invention include a resonator configured to suppress noise from an electric fan. The resonator may comprise an enclosure having an outer perimeter, a major opening through the enclosure and defining an inner perimeter of the enclosure, a minor opening disposed along the inner perimeter, and a chamber coupled to the minor opening within the enclosure between the inner and outer perimeters.

System and method for noise suppression

Embodiments of the present invention relate to a computer system. In one embodiment, the computer system comprises a fan and a muffler configured to suppress noise from the fan. The muffler may comprise a plurality of acoustic absorption sheets, wherein the acoustic absorption sheets each have a hole at least generally aligned with a flow area of the fan.

An apparatus comprises a housing comprising an air inlet, an air outlet and a divider that divides the housing into first and second air passages. The housing comprises a resonance chamber for each air passage. Each resonance chamber comprises a port, and air waves enter each such resonance chamber through such port and resonate.
