The calibration and testing of acoustical instruments by a manufacturer is primarily a quality control function. Design parameters are differentiated from production test parameters during the design phase. Design parameters are inherent in the final product and may or may not be tested during production. Production testing is performed to ensure product uniformity within tolerances set by the manufacturer, many of which are dictated by national and international standards. Type testing by a third party is often used as a means of verifying compliance to standards, often at the request of customers. Independent testing is also beneficial as a means of verifying in‐house test procedures. |
