Publication number: 20230237984Abstract: A system for protecting a hard disc drive (HDD) from acoustic energy in a chassis comprises a set of foam strips formed from acoustically absorptive material. Each foam strip has a thickness such that, when the HDD is installed in a chassis, the acoustically absorptive material is in a substantially uncompressed state. Foam strips are separated by an airflow path width, wherein two foam strips, a first surface of an HDD and a second surface form an airflow path. The second surface may be a surface of an adjacent HDD or a wall of the chassis. Each foam strip has a width and length configured for absorbing acoustic energy that would otherwise propagate through the airflow path.Type: ApplicationFiled: January 25, 2022Publication date: July 27, 2023Inventors: Jean Marie Doglio, Evangelos Konstantinos Koutsavdis, Chris E. Peterson, Paul Allen Waters

Patent number: 9671839Abstract: Acoustics management at an information handling system provides reduced acoustic noise with limited performance impact by dynamically changing power dissipation as a function of cooling fan speed and ambient temperature so that preemptive power restrictions prevent excessive thermal conditions that lead to excessive cooling fan speeds and associated acoustics. A maximum cooling fan speed of less than an available maximum is set and maintained by reducing power dissipation unless power dissipation reaches a minimum, after which the minimum power dissipation is maintained and cooling fan speed is allowed to increase.Type: GrantFiled: March 15, 2013Date of Patent: June 6, 2017Assignee: Dell Products L.P.Inventors: Chris E.
