Abstract
An acoustical enclosure for isolating high-frequency noise produced by automatic business machines, such as typewriters and teletypes. A top paper-feed housing is removable and a midsection is hinged to permit access to the enclosed machine. An exhaust fan removes heated air from the enclosure and an air-intake lip at the front of the enclosure permits ambient-temperature air to be taken into the enclosure.
