Abstract: The present invention is a noise reducing aspirator which is used to carry away air, water, saliva, dental debris from the mouth of a patient or surgical debris. The present invention comprises an open-ended large solid tubular housing having one end adapted to be connected to a source of suction and the other end adapted to be connected to an aspirator tip which will collect air, water, saliva and dental debris. The housing has a sufficient internal ejecting tubular passageway between the ends to accommodate rapid flow of air, water, saliva and dental debris therethrough. The housing includes chamfered pressure venting tubes of equal diameter circularly distributed around, and connecting to, a main suction tube via slanted pathways. The pressure venting tubes reduce and harmonize the noise level of the aspirator and avoid discomforting suction to the patient's tissue. The ends of the housing are designed to secure an aspirator tip or to a source of suction and are designed for easy removal and replacement.
