IOA in plea to NPL to reverse airborne acoustics decision

Senior IOA members are to meet National Physical Laboratory (NPL) representatives to express the Institute’s concern at its decision to cease providing services in airborne acoustics. One of the potential consequences of this decision would be the loss to the UK of the primary acoustic standard that provides traceability for microphones and calibrators (in the range 1Hz to 20 kHz). This standard is disseminated primarily via UKAS-accredited laboratories and this change would potentially affect every organisation that uses a sound level meter. The IOA is very concerned about this possible outcome and discussions have been held at Council and at a recent Measurement & Instrumentation Group committee meeting. As a result the President Jo Webb has written to the NPL seeking an urgent meeting. A positive response has been received and that meeting is expected to occur with the next week or so.
