Routine Maintenance
We want to minimise your downtime so all our engineers, field or lab-based, will carry out minor repairs (such as replacing headphone leads, cushions, batteries, etc.) as part of the calibration process.

Laboratory Repair
Before you decide to replace your existing instrument talk to us. We are able to repair most manufacturers’ models and get your tried and trusted device up and running again. All repairs which involve dis-assembly of the instrument or the replacement of a faulty transducer will be carried out in the laboratory

Prior to using the visiting service provided by AML, we were forced to ship our instruments to Dublin or the UK for service and calibration. Invariably this meant suspending our service during the shipping process and sometimes resulted in damage to our instruments during transportation. The on-site service and calibration offered by AML is much more convenient for us resulting in less downtime and lower costs. It's good to know that our instruments are calibrated and certified to the highest standards.- Cathal McGurgan, Sligo University Hospital, Ireland
We've worked with Acoustic Metrology for many years now and consider them an extremely reliable and responsive partner who understands us well and how we work. I'd have no hesitation recommending them as a calibration and repair company for audiological equipment given our past, current and hopefully future relationship.- Adrian Carragher, Head of Audiology Service, NHS Ayrshire and Arran
Calibration quick email. It was responded to straight away and within the space of 20 minutes we had booked that calibration in. And that's key not just to me but for all of my colleagues throughout Specsavers the annual calibration of equipment. Historically you send it away you haven't got it. So you have to have equipment there to cover. Very quick easy email, we've got an engineer coming round within a week who will calibrate two units at once in the same day and I haven't got to worry about it.- Mike Walker, Director of Hearing Services, Specsavers Worcester
