Cast or forged metal enclosure for mitigating noise coming from air sources for use in A dynamic air surface

The present disclosure relates generally to a noise dampening device. More specifically, but not exclusively, the disclosure relates to­­­­­­­ a cast or a forged metal enclosure for mitigating noise generated by active air movers.

 Hospital rooms can have multiple equipments and medical devices such as, compressors, blowers, suction equipment etc. that can generate noise while operating. Generally, active air movers that force air outside of the rooms and devices having vibrating surfaces can generate the most noise. Various techniques and methods have been devised to reduce the noise generated by such devices. In general such equipments were placed at far off places. However, keeping such equipment at far off places is always not feasible and can increase the structural cost. There is still room for improvement in the present noise dampening to make it usable in hospital rooms. Thus, a need persists for further contributions in this area of technology.

The disclosure provides a cast or a forged metal enclosure or housing assembly that can be used to surround air moving parts in a hospital room. The enclosure can attenuate the sound that these parts generate when operating. In accordance with the disclosure, the metal enclosure can be used with all active air movers that force air outside of a confined space, but is not limited by the direction of the air. The enclosure can include a rigid open framework and a base. The framework can be pivotally attached with the base. The framework can have two layers, an inner layer and an outer layer that can be separated by an empty space. The framework can be made of the cast or forged metal.

A hosing assembly of the cast metal enclosure according to the disclosure is represented in Fig. 1. A cast metal enclosure 102 or a housing assembly 102 housing a noise generating device 108 according to one embodiment of the disclosure is shown in Fig. 1a. The cast metal enclosure 102 can be in an open position. The cast metal enclosure 102 can be hinged to a base plate 104 at a first joint 106. The base plate 104 can hold the noise generating device 108. According to one example, when a user wants to operate the noise generating device 108, the user can completely enveloping  the noise generating device 108 by rotating the metal enclosure 102 about the first joint 106 to a closed position as shown in Fig. 1b. The metal enclosure 102 can be further provided with an opening for electrical wiring 110 and a connector 112 that can provide power to the noise generating device 108. The disclosure is not limited to a single type of noise generating device. According to an example provided in the disclosure, the noise generating device may be any pneumatic device such as a...
