Abstract

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for adjusting acoustic parameters. In one aspect, a method includes receiving an identifier associated with an enclosure for a computing device, transmitting data identifying the identifier associated with the enclosure for the computing device, and receiving one or more physical parameters of the enclosure for the computing device. The method also includes based on the one or more physical parameters of the enclosure for the computing device, determining, one or more acoustic parameter adjustments of the computing device in the enclosure, the one or more acoustic parameter adjustments being configured to preserve one or more acoustic characteristics of the computing device out of the enclosure while the computing device is in the enclosure, and based on the one or more acoustic parameter adjustments, adjusting the one or more acoustic parameters of the computing device.
